Unauthenticated code execution via redirect URL overflow
Published Apr 20, 2026 · Updated Apr 20, 2026
Heap overflow in Silex SD-330AC 1.42 and earlier and AMC Manager 5.0.2 and earlier allows remote attackers to execute code via redirect URLs. The vendor identifies the locus as the unauthenticated login redirect-URL handler but has not disclosed the operation that overflows heap storage. Reachability requires access to the affected product's HTTP or HTTPS service from the same local network; direct internet-side exploitation is not possible.
