CVE-2005-3376

15
FAUCET Score

CVE-2005-3376 describes a multiple interpretation error in Kaspersky Anti-Virus 5.0.372, allowing remote attackers to bypass virus scanning. This vulnerability occurs when files like BAT, HTML, or EML contain an "MZ" magic byte sequence, typically associated with executables, causing Kaspersky to misclassify them as safe while they can still be executed as dangerous file types by other applications. The CVSS score of 5.1 indicates a medium severity, with a network attack vector, high access complexity, and partial 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 for this vulnerability.
