CVE-2002-1777

CVE-2002-1777 describes a bypass vulnerability in Symantec Norton AntiVirus (NAV) 2002, allowing remote attackers to circumvent email scanning. Attackers could craft emails with a benign extension in the Content-Type field and a malicious one in the Content-Disposition field, which Outlook would then use. This vulnerability has a CVSS score of 7.5 (High), indicating it is easily exploitable over the network with low complexity and no authentication, potentially leading to partial confidentiality, integrity, and availability impacts. While the vendor disputed the full impact, acknowledging initial bypass but claiming subsequent detection, there is no known active exploitation, public exploit code, or Metasploit/Nuclei modules, though it has garnered significant community discussion.
