CVSS v3.1
Official Description
The management interface in the phion airlock Web Application Firewall (WAF) 4.1-10.41 does not properly handle CGI requests that specify large width and height parameters for an image, which allows remote attackers to execute arbitrary commands or cause a denial of service (resource consumption) via a crafted request.
Technical Analysis
CVE-2009-2300 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.
