CVE-2020-15786 is a critical vulnerability affecting Siemens SIMATIC HMI Basic, Comfort, and Mobile Panels, as well as Unified Comfort Panels, across various firmware versions. The flaw stems from insufficient blocking of excessive authentication attempts, enabling remote attackers to conduct brute-force attacks. This could lead to unauthorized access to the Sm@rt Server and compromise user passwords, resulting in a complete loss of confidentiality, integrity, and availability. Despite its CVSS score of 9.8 (Critical) and high FAUCET Risk Score of 78/100, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
