CVE-2026-3323

Credential disclosure via unauthenticated configuration interface

Published Apr 28, 2026 · Updated Apr 28, 2026

Missing authentication in VEGAPULS 6X firmware 1.0.0 and 1.1.0 allows remote attackers to retrieve hashed credentials and access codes. The configuration interface returns protected authentication material without authenticating the requester; the vendor has not disclosed the affected endpoint or request. Reachability requires adjacent-network access to the device; recovered values enable impersonation and subsequent authenticated device modification.
