Multiple interpretation error in unspecified versions of UNA Antivirus allows remote attackers to bypass virus detection via a malicious executable in a specially crafted RAR file with malformed central and local headers, which can still be opened by products such as Winrar and PowerZip, even though they are rejected as corrupted by Winzip and BitZipper.

Security readout for executives and security teams

This old CVE describes a way for malware inside a malformed RAR archive to evade UNA Antivirus detection. Some archive tools could still open the file, while others rejected it as corrupt. The affected UNA versions are not specified, and no active exploitation is cited. Exposure is most plausible where UNA Antivirus was used to scan email, downloads, file shares, or uploaded RAR archives. Current exposure is unclear because the CVE names unspecified versions and provides no CPEs or maintained product status. Prioritize discovery over emergency response. This is a legacy detection-bypass issue with incomplete affected-version data and no cited active exploitation. Risk increases if UNA Antivirus remains in a critical file-ingestion path. Mitigation focus: Inventory any UNA Antivirus deployments or legacy gateways that depended on it.; Check UNA or vendor guidance for archive parser fixes, replacements, or retirement advice.; Treat malformed or parser-inconsistent RAR archives as suspicious at mail and web gateways..
