CVE-2005-3370

15
FAUCET Score

CVE-2005-3370 describes a multiple interpretation error in ArcaVir 2005 package 2005-06-21. This vulnerability allows remote attackers to bypass virus scanning by crafting files (e.g., BAT, HTML, EML) with an "MZ" magic byte sequence, causing the antivirus to misidentify them as safe while still being executable as dangerous file types by other applications. Rated with a CVSS score of 5.1 (AV:N/AC:H/Au:N/C:P/I:P/A:P), it indicates a network-based attack with high access complexity, potentially leading to partial compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
