Deeper analysis
CVE-2022-47387 is a stack-based out-of-bounds write vulnerability (CWE-787) in the CmpTraceMgr component affecting multiple versions of several CODESYS products. The flaw permits an attacker to write data onto the stack, which can result in denial-of-service conditions, memory corruption, or remote code execution. It carries a CVSS 3.1 base score of 8.8 reflecting network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.
An authenticated remote attacker with valid credentials can exploit the issue over the network without user interaction to achieve those outcomes. The vulnerability therefore allows a low-privileged but authenticated actor to disrupt industrial control systems or potentially execute arbitrary code on affected devices.
Customer advisories and patches addressing the flaw are available from the CODESYS customer portal at the referenced URLs.
EPSS for the CVE currently stands at 0.0203 after having reached a peak of 0.0575.
