VAR-200604-0132
Vulnerability from variot - Updated: 2023-12-18 12:59Unspecified vulnerability in the HTTP compression functionality in Cisco CSS 11500 Series Content Services switches allows remote attackers to cause a denial of service (device reload) via (1) "valid, but obsolete" or (2) "specially crafted" HTTP requests. The Cisco CSS 11500 Content Services Switch is a load balancing device that provides robust and scalable network services (Layer 4-7) for data centers.
The Cisco CSS 11500 has a vulnerability in processing HTTP packets. Successful exploitation of this vulnerability can lead to device reloads and repeated attacks can lead to persistent denial of service. A successful attack can allow an attacker to trigger a reload on the device. A sustained denial-of-service condition can also arise due to repeated attacks.
Successful exploitation requires that the network device has been configured for HTTP compression.
SOLUTION: Update to version 8.10.1.6. http://www.cisco.com/pcgi-bin/tablebuild.pl/css11500-maint?psrtdcat20e2
Disable HTTP compression.
PROVIDED AND/OR DISCOVERED BY: Reported by vendor.
