Уязвимость компонента beh (Backend Error Handler) пакета для печати cups-filters, позволяющая нарушителю выполнить произвольные команды на сервере печати
Modified: 2024-11-21
CVE-2023-24805
cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. If you use the Backend Error Handler (beh) to create an accessible network printer, this security vulnerability can cause remote code execution. `beh.c` contains the line `retval = system(cmdline) >> 8;` which calls the `system` command with the operand `cmdline`. `cmdline` contains multiple user controlled, unsanitized values. As a result an attacker with network access to the hosted print server can exploit this vulnerability to inject system commands which are executed in the context of the running server. This issue has been addressed in commit `8f2740357` and is expected to be bundled in the next release. Users are advised to upgrade when possible and to restrict access to network printers in the meantime.

Уязвимость модуля mod_proxy веб-сервера Apache HTTP Server, позволяющая нарушителю отправить скрытый HTTP-запрос (атака типа HTTP Request Smuggling)
BDU:2023-02021
Уязвимость компонента mod_proxy_uwsgi веб-сервера Apache HTTP Server связанная с недостатками обработки HTTP-запросов, позволяющая нарушителю выполнять атаку "контрабанда HTTP-запросов"

CVE-2023-25690
Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. For example, something like: RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/ Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server.
