Armorlogic Profense Web Application Firewall before 2.2.22, and 2.4.x before 2.4.4, does not properly implement the "negative model," which allows remote attackers to conduct cross-site scripting (XSS) attacks via a modified end tag of a SCRIPT element.

Security readout for executives and security teams

This is a legacy Armorlogic Profense Web Application Firewall flaw. Certain Profense versions could fail to block a modified script-ending pattern, allowing cross-site scripting traffic through the WAF. Business urgency is mainly for organizations still running old Profense appliances or relying on them as the primary XSS control. Exposure is likely limited to legacy environments using Armorlogic Profense versions older than 2.2.22, or 2.4.x before 2.4.4, especially where application XSS defenses depend on the WAF. Treat as targeted legacy risk. Prioritize quickly if Profense is still deployed in front of business-critical web apps; otherwise document non-applicability and move on. Mitigation focus: Identify any Armorlogic Profense WAF deployments and recorded software versions.; Upgrade affected Profense systems to 2.2.22, 2.4.4, or later where applicable.; Do not rely on WAF filtering as the only XSS defense..
