TITLE

Cisco Web Security Runs on the appliance device AsyncOS Service disruption in the implementation of proxy caches (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2015-005766

DESCRIPTION

The proxy-cache implementation in Cisco AsyncOS 8.0.x before 8.0.7-151, 8.1.x and 8.5.x before 8.5.2-004, 8.6.x and 8.7.x before 8.7.0-171-LD, and 8.8.x before 8.8.0-085 on Web Security Appliance (WSA) devices allows remote attackers to cause a denial of service (memory consumption) via multiple proxy connections, aka Bug ID CSCus10922. The Cisco Web Security Appliance is a network security appliance from Cisco. A security vulnerability exists in the proxy cache feature of Cisco AsyncOS in Cisco WSA appliances. The program failed to handle the memory correctly. Attackers can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCus10922. The following releases are affected: Cisco AsyncOS 8.0.x prior to 8.0.7-151, 8.1.x and 8.5.x prior to 8.5.2-004, 8.6.x and 8.7.x prior to 8.7.0-171-LD Version, 8.8.x version before 8.8.0-085
