PHP 8.2.x < 8.2.20 Multiple Vulnerabilities

critical Nessus Plugin ID 200162

Synopsis

The version PHP running on the remote web server is affected by multiple vulnerabilities.

Description

The version of PHP installed on the remote host is prior to 8.2.20. It is, therefore, affected by multiple vulnerabilities as referenced in the Version 8.2.20 advisory.

 - In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, when using Apache and PHP- CGI on Windows, if the system is set up to use certain code pages, Windows may use Best-Fit behavior to replace characters in command line given to Win32 API functions. PHP CGI module may misinterpret those characters as PHP options, which may allow a malicious user to pass options to PHP binary being run, and thus reveal the source code of scripts, run arbitrary PHP code on the server, etc. (CVE-2024-4577)

 - In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, due to a code logic error, filtering functions such as filter_var when validating URLs (FILTER_VALIDATE_URL) for certain types of URLs the function will result in invalid user information (username + password part of URLs) being treated as valid user information. This may lead to the downstream code accepting invalid URLs as valid and parsing them incorrectly. (CVE-2024-5458)

 - In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, the fix for CVE-2024-1874 does not work if the command name includes trailing spaces. Original issue: when using proc_open() command with array syntax, due to insufficient escaping, if the arguments of the executed command are controlled by a malicious user, the user can supply arguments that would execute arbitrary commands in Windows shell.
 (CVE-2024-5585)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 8.2.20 or later.
