CVE-2024-28182
CVSS v3.1
7.5
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
nghttp2 versions prior to 1.61.0
Description
The nghttp2 library keeps reading an unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync, causing excessive CPU usage to decode the HPACK stream. This issue can be exploited by a remote attacker to cause a denial of service.
Recommendations
For nghttp2 versions prior to 1.61.0, update to version 1.61.0 or later to mitigate the vulnerability by limiting the number of CONTINUATION frames accepted per stream. As a temporary workaround, consider restricting the use of HTTP/2 CONTINUATION frames until a patch is available.
