Apache Traffic Server 5.3.x < 5.3.2 HTTP2 Multiple Vulnerabilities

Critical Nessus Plugin ID 87241


The remote caching server is affected by multiple vulnerabilities.


According to its banner, the version of Apache Traffic Server running on the remote host is 5.3.x prior to 5.3.2. It is, therefore, affected by multiple vulnerabilities related to improper handling of HTTP/2 requests. An attacker can exploit these vulnerabilities to have an unspecified impact. No further details are available.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to Apache Traffic Server version 5.3.2 or later.
Alternatively, disable HTTP/2 support.
