CVE-2009-1593

21
FAUCET Score

CVE-2009-1593 describes a cross-site scripting (XSS) vulnerability in Armorlogic Profense Web Application Firewall versions before 2.2.22 and 2.4.x before 2.4.4. The flaw stems from an improper implementation of the "negative model," allowing remote attackers to bypass the WAF by manipulating SCRIPT end tags. This medium-complexity attack (CVSS 4.3) could lead to information disclosure or client-side script execution, but does not impact availability. While an ExploitDB entry exists, there is no evidence of active exploitation, Metasploit modules, or significant community discussion or media coverage.
