Deeper analysis
CVE-2022-47382 is a stack-based out-of-bounds write vulnerability (CWE-787) residing in the CmpTraceMgr component of multiple CODESYS products across various versions. The flaw carries a CVSS 3.1 score of 8.8 and permits an attacker to write attacker-controlled data onto the stack, potentially resulting in denial of service, memory corruption, or remote code execution.
An authenticated remote attacker with network access can exploit the issue without user interaction. Because the attack requires valid credentials but no other preconditions, a compromised or low-privileged account on an exposed CODESYS installation is sufficient to trigger the out-of-bounds write and achieve the impacts described above.
CODESYS has released security advisories and associated patches for affected products; the primary advisory and download are available at the customer portal URLs referenced for this CVE.
EPSS for the vulnerability rose from a low baseline to a peak of 0.0575 on 2026-03-11 before receding to the current value of 0.0203, indicating a measurable increase in observed exploitation interest after disclosure.
