In PHP 8.3.* before 8.3.5, function mb_encode_mimeheader() runs endlessly for some inputs that contain long strings of non-space characters followed by a space. This could lead to a potential DoS attack if a hostile user sends data to an application that uses this function.

The remote host is affected by the vulnerability described in GLSA-202408-32 (PHP: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the CVE identifiers referenced below     for details.

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

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

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 8.1.28, 8.2.x prior to 8.2.18, or 8.3.x prior to 8.3.6. It is, therefore, affected by multiple vulnerabilities:

 - A command injection via array-ish $command parameter of proc_open. (CVE-2024-1874)

 - __Host-/__Secure- cookie bypass due to partial CVE-2022-31629 fix. (CVE-2024-2756)

 - password_verify can erroneously return true, opening ATO risk. (CVE-2024-3096)

 - mb_encode_mimeheader runs endlessly for some inputs. (CVE-2024-2757)

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 FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 6d82c5e9-fc24-11ee-a689-04421a1baf97 advisory.

  - This update includes 3 security fixes: (CVE-2024-1874, CVE-2024-2756, CVE-2024-2757, CVE-2024-3096)

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 8.3.6. It is, therefore, affected by multiple vulnerabilities as referenced in the Version 8.3.6 advisory.

  - In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site     attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or     `__Secure-` cookie by PHP applications. (CVE-2022-31629)

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