F5 Networks BIG-IP : HTTP/2 vulnerability (K000137106)

medium Nessus Plugin ID 183052

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 15.1.10.4 / 16.1.4.3 / 17.1.1.3. It is, therefore, affected by a vulnerability as referenced in the K000137106 advisory.

 The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.(CVE-2023-44487also known as HTTP/2 Rapid Reset Attack)

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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 one of the non-vulnerable versions listed in the F5 Solution K000137106.
