The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-6053-1 advisory.

  • In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, password_verify() function may accept some invalid Blowfish hashes as valid. If such invalid hash ever ends up in the password database, it may lead to an application allowing any password for this entry as valid. (CVE-2023-0567)

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