CVE-2023-20198 is a critical unauthenticated privilege escalation vulnerability in Cisco IOS XE software's web UI feature. Exploited as a zero-day before Cisco published any advisory, attackers used it to create administrator accounts and then chained it with CVE-2023-20273 to deploy a persistent Lua-based implant on over 50,000 network devices. No authentication or user interaction required.
CVE-2022-1388 is a critical authentication bypass vulnerability in the F5 BIG-IP iControl REST management API. Unauthenticated attackers with network access to the management interface can execute arbitrary OS commands as root by manipulating HTTP headers to bypass the API authentication layer. Mass exploitation began within 24 hours of F5's advisory. CISA and FBI issued a joint advisory warning of active exploitation.
CVE-2020-5902 is a critical remote code execution vulnerability in the F5 BIG-IP Traffic Management User Interface (TMUI). An unauthenticated attacker with network access to the TMUI can execute arbitrary system commands, create or delete files, enable or disable services, and fully compromise the BIG-IP device. With a CVSS score of 10.0, this vulnerability was exploited within hours of F5's advisory.
