"The version of php installed on the remote host is prior to 8.0.24-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2PHP8.0-2023-005 advisory.

  - In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the phar uncompressor code would recursively uncompress
    quines gzip files, resulting in an infinite loop. (CVE-2022-31628)

  - 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.");
