CVE-2026-35089Network attack vector

Admin credential disclosure via predictable secure key

Published May 27, 2026 · Updated May 27, 2026

Weak credential generation in Slican IPx, CCT-1668, MAC-6400, and CXS-0424 allows remote attackers to obtain admin credentials. The exchanges deterministically generate a secure key from device properties that unauthenticated requests disclose, allowing the key to be deduced. Network reachability to an exchange is sufficient; the disclosed administrator credentials expose its management functions, with no reported integrity or availability impact.
