CVE-2022-20904 describes multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. These vulnerabilities stem from insufficient validation of user fields in HTTP packets. An authenticated, remote attacker could exploit these to achieve arbitrary code execution with root privileges or cause a denial of service by unexpectedly restarting the device. The CVSS score is 7.2 (High), indicating a network-based attack with high impact on confidentiality, integrity, and availability, requiring high privileges but low attack complexity. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage for this vulnerability.
