7.5
CVSS v3.1
Official Description
Armorlogic Profense Web Application Firewall before 2.2.22, and 2.4.x before 2.4.4, does not properly implement the "positive model," which allows remote attackers to bypass certain protection mechanisms via a %0A (encoded newline), as demonstrated by a %0A in a cross-site scripting (XSS) attack URL.
Technical Analysis
CVE-2009-1594 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
