FAUCET Score

CVE-2013-2011 describes a critical PHP code-execution vulnerability in the WordPress W3 Super Cache Plugin prior to version 1.3.2, affecting automattic w3_super_cache. This flaw, an incomplete fix for a previous vulnerability, allows remote attackers to inject arbitrary code. With a CVSS score of 8.8 (HIGH), the vulnerability is easily exploitable over the network with low attack complexity, potentially leading to complete compromise of confidentiality, integrity, and availability.
