CVE-2020-12069 affects CODESYS V3 products, including those from Festo, Pilz, and Wago, specifically versions prior to V3.5.16.0 that contain the CmpUserMgr component. This vulnerability stems from the CODESYS Control runtime system using a weak hashing algorithm for online communication passwords. A local attacker with low privileges could exploit this to gain full control of the device, as indicated by its CVSS score of 7.8 (High) with an attack vector of local and low attack complexity. There is no evidence of active exploitation, no public exploit code available (Metasploit, Nuclei, ExploitDB), and minimal community discussion, suggesting it is not currently a high-profile threat.
