In Cacti through 1.2.6, authenticated users may bypass authorization checks (for viewing a graph) via a direct graph_json.php request with a modified local_graph_id parameter.

Cacti through 1.2.7 is affected by a graphs.php?template_id= SQL injection vulnerability affecting how template identifiers are handled when a string and id composite value are used to identify the template type and id. An authenticated attacker can exploit this to extract data from the database, or an unauthenticated remote attacker could exploit this via Cross-Site Request Forgery.

Cacti through 1.2.7 is affected by multiple instances of lib/functions.php unsafe deserialization of user-controlled data to populate arrays. An authenticated attacker could use this to influence object data values and control actions taken by Cacti or potentially cause memory corruption in the PHP module.

In Cacti before 1.2.11, disabling a user account does not immediately invalidate any permissions granted to that account (e.g., permission to view logs).

In Cacti before 1.2.11, auth_profile.php?action=edit allows CSRF for an admin email change.

Cacti before 1.2.18 allows remote attackers to trigger XSS via template import for the midwinter theme.

An issue was discovered in Cacti 1.2.x through 1.2.16. A SQL injection vulnerability in data_debug.php allows remote authenticated attackers to execute arbitrary SQL commands via the site_id parameter. This can lead to remote code execution.

Cacti 1.2.8 has stored XSS in data_sources.php, color_templates_item.php, graphs.php, graph_items.php, lib/api_automation.php, user_admin.php, and user_group_admin.php, as demonstrated by the description parameter in data_sources.php (a raw string from the database that is displayed by $header to trigger the XSS).

Cacti 1.2.8 allows Remote Code Execution (by privileged users) via shell metacharacters in the Performance Boost Debug Log field of poller_automation.php. OS commands are executed when a new poller cycle begins. The attacker must be authenticated, and must have access to modify the Performance Settings of the product.

graph_realtime.php in Cacti 1.2.8 allows remote attackers to execute arbitrary OS commands via shell metacharacters in a cookie, if a guest user has the graph real-time privilege.

Cacti is an open source platform which provides a robust and extensible operational monitoring and fault management framework for users. In affected versions a command injection vulnerability allows an unauthenticated user to execute arbitrary code on a server running Cacti, if a specific data source was selected for any monitored device. The vulnerability resides in the `remote_agent.php` file. This file can be accessed without authentication. This function retrieves the IP address of the client via `get_client_addr` and resolves this IP address to the corresponding hostname via `gethostbyaddr`. After this, it is verified that an entry within the `poller` table exists, where the hostname corresponds to the resolved hostname. If such an entry was found, the function returns `true` and the client is authorized. This authorization can be bypassed due to the implementation of the `get_client_addr` function. The function is defined in the file `lib/functions.php` and checks serval `$_SERVER` variables to determine the IP address of the client. The variables beginning with `HTTP_` can be arbitrarily set by an attacker. Since there is a default entry in the `poller` table with the hostname of the server running Cacti, an attacker can bypass the authentication e.g. by providing the header `Forwarded-For: `. This way the function `get_client_addr` returns the IP address of the server running Cacti. The following call to `gethostbyaddr` will resolve this IP address to the hostname of the server, which will pass the `poller` hostname check because of the default entry. After the authorization of the `remote_agent.php` file is bypassed, an attacker can trigger different actions. One of these actions is called `polldata`. The called function `poll_for_data` retrieves a few request parameters and loads the corresponding `poller_item` entries from the database. If the `action` of a `poller_item` equals `POLLER_ACTION_SCRIPT_PHP`, the function `proc_open` is used to execute a PHP script. The attacker-controlled parameter `$poller_id` is retrieved via the function `get_nfilter_request_var`, which allows arbitrary strings. This variable is later inserted into the string passed to `proc_open`, which leads to a command injection vulnerability. By e.g. providing the `poller_id=;id` the `id` command is executed. In order to reach the vulnerable call, the attacker must provide a `host_id` and `local_data_id`, where the `action` of the corresponding `poller_item` is set to `POLLER_ACTION_SCRIPT_PHP`. Both of these ids (`host_id` and `local_data_id`) can easily be bruteforced. The only requirement is that a `poller_item` with an `POLLER_ACTION_SCRIPT_PHP` action exists. This is very likely on a productive instance because this action is added by some predefined templates like `Device - Uptime` or `Device - Polling Time`. This command injection vulnerability allows an unauthenticated user to execute arbitrary commands if a `poller_item` with the `action` type `POLLER_ACTION_SCRIPT_PHP` (`2`) is configured. The authorization bypass should be prevented by not allowing an attacker to make `get_client_addr` (file `lib/functions.php`) return an arbitrary IP address. This could be done by not honoring the `HTTP_...` `$_SERVER` variables. If these should be kept for compatibility reasons it should at least be prevented to fake the IP address of the server running Cacti. This vulnerability has been addressed in both the 1.2.x and 1.3.x release branches with `1.2.23` being the first release containing the patch.

Cacti is an open source operational monitoring and fault management framework. There are two instances of insecure deserialization in Cacti version 1.2.24. While a viable gadget chain exists in Cacti’s vendor directory (phpseclib), the necessary gadgets are not included, making them inaccessible and the insecure deserializations not exploitable. Each instance of insecure deserialization is due to using the unserialize function without sanitizing the user input. Cacti has a “safe” deserialization that attempts to sanitize the content and check for specific values before calling unserialize, but it isn’t used in these instances. The vulnerable code lies in graphs_new.php, specifically within the host_new_graphs_save function. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti before 1.2.6 allows IDOR (Insecure Direct Object Reference) for accessing any graph via a modified local_graph_id parameter to graph_xport.php. This is a different vulnerability than CVE-2019-16723.

Cacti is an open source operational monitoring and fault management framework. An authenticated SQL injection vulnerability was discovered which allows authenticated users to perform privilege escalation and remote code execution. The vulnerability resides in the `reports_user.php` file. In `ajax_get_branches`, the `tree_id` parameter is passed to the `reports_get_branch_select` function without any validation. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti is an open source operational monitoring and fault management framework. An authenticated SQL injection vulnerability was discovered which allows authenticated users to perform privilege escalation and remote code execution. The vulnerability resides in the `graphs.php` file. When dealing with the cases of ajax_hosts and ajax_hosts_noany, if the `site_id` parameter is greater than 0, it is directly reflected in the WHERE clause of the SQL statement. This creates an SQL injection vulnerability. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti is an open source operational monitoring and fault management framework. In Cacti 1.2.24, under certain conditions, an authenticated privileged user, can use a malicious string in the SNMP options of a Device, performing command injection and obtaining remote code execution on the underlying server. The `lib/snmp.php` file has a set of functions, with similar behavior, that accept in input some variables and place them into an `exec` call without a proper escape or validation. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti is an open source operational monitoring and fault management framework. Issues with Cacti Regular Expression validation combined with the external links feature can lead to limited SQL Injections and subsequent data leakage. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti provides an operational monitoring and fault management framework. In versions 1.2.25 and prior, it is possible to execute arbitrary SQL code through the `pollers.php` script. An authorized user may be able to execute arbitrary SQL code. The vulnerable component is the `pollers.php`. Impact of the vulnerability - arbitrary SQL code execution. As of time of publication, a patch does not appear to exist.

Cacti is an open source operational monitoring and fault management framework. The fix applied for CVE-2023-39515 in version 1.2.25 is incomplete as it enables an adversary to have a victim browser execute malicious code when a victim user hovers their mouse over the malicious data source path in `data_debug.php`. To perform the cross-site scripting attack, the adversary needs to be an authorized cacti user with the following permissions: `General Administration>Sites/Devices/Data`. The victim of this attack could be any account with permissions to view `http:///cacti/data_debug.php`. As of time of publication, no complete fix has been included in Cacti.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, an arbitrary file write vulnerability, exploitable through the "Package Import" feature, allows authenticated users having the "Import Templates" permission to execute arbitrary PHP code on the web server. The vulnerability is located within the `import_package()` function defined into the `/lib/import.php` script. The function blindly trusts the filename and file content provided within the XML data, and writes such files into the Cacti base path (or even outside, since path traversal sequences are not filtered). This can be exploited to write or overwrite arbitrary files on the web server, leading to execution of arbitrary PHP code or other security impacts. Version 1.2.27 contains a patch for this issue.

Cacti provides an operational monitoring and fault management framework. Versions of Cacti prior to 1.2.27 are vulnerable to stored cross-site scripting, a type of cross-site scripting where malicious scripts are permanently stored on a target server and served to users who access a particular page. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Versions of Cacti prior to 1.2.27 contain a residual cross-site scripting vulnerability caused by an incomplete fix for CVE-2023-50250. `raise_message_javascript` from `lib/functions.php` now uses purify.js to fix CVE-2023-50250 (among others). However, it still generates the code out of unescaped PHP variables `$title` and `$header`. If those variables contain single quotes, they can be used to inject JavaScript code. An attacker exploiting this vulnerability could execute actions on behalf of other users. This ability to impersonate users could lead to unauthorized changes to settings. Version 1.2.27 fixes this issue.

Cacti provides an operational monitoring and fault management framework. Prior to 1.2.27, some of the data stored in `form_save()` function in `data_queries.php` is not thoroughly checked and is used to concatenate the HTML statement in `grow_right_pane_tree()` function from `lib/html.php` , finally resulting in cross-site scripting. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, some of the data stored in `automation_tree_rules_form_save()` function in `automation_tree_rules.php` is not thoroughly checked and is used to concatenate the HTML statement in `form_confirm()` function from `lib/html.php` , finally resulting in cross-site scripting. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, a SQL injection vulnerability in `automation_get_new_graphs_sql` function of `api_automation.php` allows authenticated users to exploit these SQL injection vulnerabilities to perform privilege escalation and remote code execution. In `api_automation.php` line 856, the `get_request_var('filter')` is being concatenated into the SQL statement without any sanitization. In `api_automation.php` line 717, The filter of `'filter'` is `FILTER_DEFAULT`, which means there is no filter for it. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, some of the data stored in `form_save()` function in `graph_template_inputs.php` is not thoroughly checked and is used to concatenate the SQL statement in `draw_nontemplated_fields_graph_item()` function from `lib/html_form_templates.php` , finally resulting in SQL injection. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, there is a file inclusion issue in the `lib/plugin.php` file. Combined with SQL injection vulnerabilities, remote code execution can be implemented. There is a file inclusion issue with the `api_plugin_hook()` function in the `lib/plugin.php` file, which reads the plugin_hooks and plugin_config tables in database. The read data is directly used to concatenate the file path which is used for file inclusion. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, some of the data stored in `automation_tree_rules.php` is not thoroughly checked and is used to concatenate the SQL statement in `create_all_header_nodes()` function from `lib/api_automation.php` , finally resulting in SQL injection. Using SQL based secondary injection technology, attackers can modify the contents of the Cacti database, and based on the modified content, it may be possible to achieve further impact, such as arbitrary file reading, and even remote code execution through arbitrary file writing. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, Cacti calls `compat_password_hash` when users set their password. `compat_password_hash` use `password_hash` if there is it, else use `md5`. When verifying password, it calls `compat_password_verify`. In `compat_password_verify`, `password_verify` is called if there is it, else use `md5`. `password_verify` and `password_hash` are supported on PHP < 5.5.0, following PHP manual. The vulnerability is in `compat_password_verify`. Md5-hashed user input is compared with correct password in database by `$md5 == $hash`. It is a loose comparison, not `===`. It is a type juggling vulnerability. Version 1.2.27 contains a patch for the issue.

Cacti is an open source performance and fault management framework. The `fileurl` parameter is not properly sanitized when saving external links in `links.php` . Morever, the said fileurl is placed in some html code which is passed to the `print` function in `link.php` and `index.php`, finally leading to stored XSS. Users with the privilege to create external links can manipulate the `fileurl` parameter in the http post request while creating external links to perform stored XSS attacks. The vulnerability known as XSS (Cross-Site Scripting) occurs when an application allows untrusted user input to be displayed on a web page without proper validation or escaping. This issue has been addressed in release version 1.2.28. All users are advised to upgrade. There are no known workarounds for this issue.

Cacti is an open source performance and fault management framework. An admin user can create a device with a malicious hostname containing php code and repeat the installation process (completing only step 5 of the installation process is enough, no need to complete the steps before or after it) to use a php file as the cacti log file. After having the malicious hostname end up in the logs (log poisoning), one can simply go to the log file url to execute commands to achieve RCE. This issue has been addressed in version 1.2.28 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti is an open source performance and fault management framework. The `title` parameter is not properly sanitized when saving external links in links.php . Morever, the said title parameter is stored in the database and reflected back to user in index.php, finally leading to stored XSS. Users with the privilege to create external links can manipulate the `title` parameter in the http post request while creating external links to perform stored XSS attacks. The vulnerability known as XSS (Cross-Site Scripting) occurs when an application allows untrusted user input to be displayed on a web page without proper validation or escaping. This issue has been addressed in release version 1.2.28. All users are advised to upgrade. There are no known workarounds for this vulnerability.
