28
FAUCET Score

CVE-2009-0311 describes a critical remote code execution vulnerability in the Backbone service (ftbackbone.exe) of EMC AutoStart versions prior to 5.3 SP2. An unauthenticated attacker can exploit this by sending a specially crafted packet that causes a function pointer to be dereferenced, leading to arbitrary code execution. This vulnerability carries a CVSS score of 10.0, indicating maximum severity with a network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. While no public exploit intelligence (Metasploit, Nuclei, ExploitDB) or active exploitation is reported, and community discussion is minimal, the high FAUCET Risk Score of 90/100 highlights its significant potential impact.
