Multiple CODESYS Products are prone to a out-of bounds read or write access. A low privileged remote attacker may craft a request with invalid offset, which can cause an out-of-bounds read or write access, resulting in denial-of-service condition or local memory overwrite, which can lead to a change of local files. User interaction is not required.

Exploit prediction (EPSS)

1.08% probability of exploitation in the next 30 days, higher than 65% of all scored CVEs.
