"The version of php installed on the remote host is prior to 7.4.33. It is, therefore, affected by multiple
vulnerabilities as referenced in the SSA:2022-314-01 advisory.

  - The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer
    overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties.
    This occurs in the sponge function interface. (CVE-2022-37454)

  - The vulnerability exists due to a boundary condition within the imageloadfont() function. A remote
    attacker can pass specially crafted data to the web application, trigger an out-of-bounds read error and
    read contents of memory on the system. (CVE-2022-31630)

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