Cisco PIX/ASA 7.1.x before 7.1(2) and 7.0.x before 7.0(5), PIX 6.3.x before 6.3.5(112), and FWSM 2.3.x before 2.3(4) and 3.x before 3.1(7), when used with Websense/N2H2, allows remote attackers to bypass HTTP access restrictions by splitting the GET method of an HTTP request into multiple packets, which prevents the request from being sent to Websense for inspection, aka bugs CSCsc67612, CSCsc68472, and CSCsd81734.

Security readout for executives and security teams

This is a content-filter bypass in older Cisco PIX, ASA, and FWSM deployments using Websense or N2H2. A user could evade HTTP access restrictions, so the business impact is policy bypass rather than device takeover based on the supplied sources. Exposure is limited to legacy Cisco PIX, ASA, or FWSM versions configured with Websense or N2H2 HTTP content filtering. Deployments not using those filtering integrations are not described as affected in the supplied sources. Prioritize if any legacy Cisco firewall still enforces web access policy through Websense or N2H2. Otherwise, treat as a legacy exposure check during firewall inventory and modernization work. Mitigation focus: Upgrade affected Cisco PIX, ASA, and FWSM software to the fixed versions named by Cisco.; Confirm whether Websense or N2H2 integration is enabled on legacy firewall paths.; Check Cisco's advisory for branch-specific upgrade and operational guidance..
