CVE-2026-76992Uncontrolled Memory Allocation in CODESYS Gateway Client

CODESYS Development System 3; CODESYS Gateway; CODESYS Edge Gateway for Windows; CODESYS HMI (SL) Veröffentlicht: (vor 1 Monat)

Beschreibung

The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit. An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory consumption, resulting in a denial-of-service condition thus leading to a total loss of availablity.

Schwachstellentyp (CWE): CWE-770
