In short
An authenticated attacker can write data beyond buffer boundaries in CODESYS software, potentially crashing the system, corrupting memory, or executing malicious code remotely.
Technical detail
Stack-based buffer overflow in CmpTraceMgr component allows authenticated remote adversaries to write out-of-bounds data, enabling DoS, arbitrary memory corruption, or RCE depending on exploit conditions and memory layout.
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.
