high Nessus Plugin ID 146311

Synopsis

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

Description

The version of PHP installed on the remote host is 7.3.x prior to 7.3.27, 7.4.x prior to 7.4.15, or 8.x prior to 8.0.2.
It is, therefore, affected by a denial of service (DoS) vulnerability due to a null dereference in SoapClient. An unauthenticated, remote attacker can exploit this, by providing an XML to the SoapCLient query() function without an existing field, in order to cause PHP to crash.

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

Solution

Upgrade to PHP version 7.3.27, 7.4.15, 8.0.2 or later.
