About this tag
CVE-2022-0778 is an OpenSSL parsing bug that can trigger an infinite loop and denial-of-service condition when a crafted certificate or key is parsed. The vulnerability stems from OpenSSL's BN_mod_sqrt function. On WindowsForum.com, discussions focus on its impact on industrial devices, particularly Siemens products such as SCALANCE, RUGGEDCOM, SIMATIC, SIMOTION, and SIPLUS families. The Siemens advisory SSA-712929 and CISA guidance highlight the operational risk for Windows-centric IT teams managing these devices. Another thread covers the Siemens Brownfield Connectivity Client (BFCClient), which bundles multiple OpenSSL flaws including CVE-2022-0778, urging updates to V2.17 or later. Mitigation strategies include patching and network-level controls.
