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

- 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)
