Unauthenticated code execution via Cookie parser overflow
Published Jul 31, 2026 · Updated Jul 31, 2026
Stack-based buffer overflow in Advantech ADAM-3600 EdgeLink before 2.8.5.1 allows remote attackers to execute code through Cookie parsing. The published record identifies the Cookie parsing methods as the locus but does not disclose the malformed input or exact bounds-checking failure. SafeEnhancement must be enabled; no authentication or user interaction is required, and successful exploitation executes attacker-controlled code.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
