In short
A flaw in CODESYS products lets an authenticated attacker write data beyond memory boundaries on the stack, which can crash the system, corrupt data, or run malicious code.
Technical detail
An authenticated remote attacker can exploit a stack-based out-of-bounds write vulnerability (CWE-787) in multiple CODESYS product versions to overwrite stack memory, leading to denial-of-service, memory corruption, or arbitrary code execution. Requires prior authentication to the affected system.
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 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.
