The version of php80 installed on the remote host is prior to 8.0.25 / 8.1.12. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-304-02 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)

  • In PHP versions prior to 7.4.33, 8.0.25 and 8.2.12, when using imageloadfont() function in gd extension, it is possible to supply a specially crafted font file, such as if the loaded font is used with imagechar() function, the read outside allocated buffer will be used. This can lead to crashes or disclosure of confidential information. (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.
