Norton Anti-Virus (NAV) allows remote attackers to bypass content filtering via attachments whose Content-Type and Content-Disposition headers are mixed upper and lower case, which is ignored by some mail clients.

Security readout for executives and security teams

CVE-2002-0485 is an old Norton Anti-Virus mail-filtering bypass. The reported issue could let a remote sender get an attachment past NAV content filtering by exploiting inconsistent case handling in email attachment headers. Business impact depends on whether any legacy NAV mail filtering remains in use. Exposure is most likely in legacy environments still relying on old Norton Anti-Virus mail content filtering. The source bundle lists affected vendor, product, versions, and CPEs as n/a, so precise product scoping is incomplete. Prioritize validation if the organization has old mail infrastructure or inherited antivirus gateways. For modern environments without NAV mail filtering, urgency is lower, but historical systems should be checked because the issue is a direct content-filter bypass. Mitigation focus: Identify and retire any legacy NAV mail-filtering deployments.; Check Norton or Symantec guidance for affected versions and fixes.; Use current email security controls that normalize MIME header case consistently..

Improper Handling of Case Sensitivity

Improper Handling of Case Sensitivity represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
