In short
A flaw in CODESYS products allows an authenticated attacker to write data beyond memory boundaries on the stack, potentially crashing the system, corrupting memory, or executing malicious code.
Technical detail
Stack-based buffer overflow in CmpTraceMgr component exploitable by authenticated remote attackers; attack vector requires prior authentication and can result in denial-of-service, memory corruption, or arbitrary code execution through stack manipulation.
Summary generated and translated by AI from the official description.
An authenticated, remote attacker may use a stack based out-of-bounds write vulnerability in the CmpTraceMgr Component of multiple CODESYS products in multiple versions to write data into the stack which can lead to a denial-of-service condition, memory overwriting, or remote code execution.
