"The version of PHP installed on the remote host is prior to 8.0.29. It is, therefore, affected by a vulnerability as
referenced in the Version 8.0.29 advisory.

  - In PHP versions 8.0.* before 8.0.29, 8.1.* before 8.1.20, 8.2.* before 8.2.7 when using SOAP HTTP Digest
    Authentication, random value generator was not checked for failure, and was using narrower range of values
    than it should have. In case of random generator failure, it could lead to a disclosure of 31 bits of
    uninitialized memory from the client to the server, and it also made easier to a malicious server to guess
    the client's nonce. (CVE-2023-3247)

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