Researchers disclose a critical severity vulnerability affecting PHP installations and provide proof-of-concept exploit code, which could lead to remote code execution.

CVE-2024-4577: Proof of Concept Available for PHP-CGI Argument Injection Vulnerability

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.

Researchers say there is widespread exploitation of this known vulnerability across various regions. Organizations are advised to patch this flaw if they have not yet done so.

In-the-wild exploitation of this flaw by TellYouThePass ransomware has been detected. Patching is strongly advised.

Due to the widespread use of PHP and XAMPP for Windows being impacted by default, we recommend prioritizing patching of this RCE.

The version of PHP: Hypertext Preprocessor detected on the remote Windows host is 8.1.x prior to 8.1.29, 8.2.x prior to 8.2.20, or 8.3.x prior to 8.3.8. It is, therefore, affected by an arbitrary code execution vulnerability:

  - 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)

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

The remote Fedora 41 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-a03b06dbd0 advisory.

    **OpenSSL:**

    * The openssl_private_decrypt function in PHP, when using PKCS1 padding (OPENSSL_PKCS1_PADDING, which is     the default), is vulnerable to the Marvin Attack unless it is used with an OpenSSL version that includes     the changes from this pull request: https://github.com/openssl/openssl/pull/13817     (rsa_pkcs1_implicit_rejection). These changes are part of OpenSSL 3.2 and have also been backported to     stable versions of various Linux distributions, as well as to the PHP builds provided for Windows since     the previous release. All distributors and builders should ensure that this version is used to prevent PHP     from being vulnerable. (**CVE-2024-2408**)

    **Standard:**

    * Fixed bug [GHSA-9fcc-425m-g385](https://github.com/php/php-src/security/advisories/GHSA-9fcc-425m-g385)     (Bypass of CVE-2024-1874). (CVE-2024-5585) (nielsdos)

    **XML:**

    * Fixed bug [GH-14124](https://github.com/php/php-src/issues/14124) (Segmentation fault with XML extension     under certain memory limit). (nielsdos)

    **XMLReader:**

    * Fixed bug [GH-14183](https://github.com/php/php-src/issues/14183) (XMLReader::open() can't be     overridden). (nielsdos)


Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

According to its self-reported version number, the version of PHP installed on the remote host is 8.1.x prior to 8.1.29, 8.2.x prior to 8.2.20, or 8.3.x prior to 8.3.8. It is, therefore, affected by multiple vulnerabilities:

 - An argument Injection in PHP-CGI with a bypass of CVE-2012-1823. (CVE-2024-4577)

 - A filter bypass in filter_var FILTER_VALIDATE_URL. (CVE-2024-5458)

 - A bypass of CVE-2024-1874. (CVE-2024-5585)

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

The version of php81 installed on the remote host is prior to 8.1.29 / 8.3.8. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2024-158-01 advisory.

    New php packages are available for Slackware 15.0 and -current to fix security issues.

Tenable has extracted the preceding description block directly from the php81 security advisory.

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

The version of PHP installed on the remote host is prior to 8.1.29. It is, therefore, affected by multiple vulnerabilities as referenced in the Version 8.1.29 advisory.

  - sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before 5.4.2, when configured as a CGI script (aka php-     cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote     attackers to execute arbitrary code by placing command-line options in the query string, related to lack     of skipping a certain php_getopt for the 'd' case. (CVE-2012-1823)

  - In PHP versions 8.1.* before 8.1.28, 8.2.* before 8.2.18, 8.3.* before 8.3.5, 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-2024-1874)

  - 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.

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.
