20
FAUCET Score

CVE-2007-3285 describes a vulnerability in Mozilla Firefox versions prior to 2.0.0.5, specifically when running on Windows. It allows remote attackers to bypass file type checks by using a file:/// or resource: URI with a dangerous extension, followed by a NULL byte and a safer extension, causing a discrepancy in how Firefox and Windows interpret the file. This medium-severity vulnerability (CVSS 6.8) has a network attack vector, medium attack complexity, and potential impact on confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
