PHP 8.1.x < 8.1.20

medium Nessus Plugin ID 177510

Language:

Synopsis

The version PHP running on the remote web server is affected by a vulnerability.

Description

The version of PHP installed on the remote host is prior to 8.1.20. It is, therefore, affected by a vulnerability as referenced in the Version 8.1.20 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.

Solution

Upgrade to PHP version 8.1.20 or later.
