"The version of nghttp2 installed on the remote host is prior to 1.41.0-1. It is, therefore, affected by a vulnerability
as referenced in the ALAS2-2024-2523 advisory.
nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior
to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is
reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2
v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream.
There is no workaround for this vulnerability. (CVE-2024-28182)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
