CVE-2021-1177

CVE-2021-1177 describes multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. These flaws, stemming from improper input validation, could allow an authenticated, remote attacker to execute arbitrary code as root or cause a denial of service. The vulnerability carries a CVSS score of 7.2 (High) due to its network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability, though it requires valid administrator credentials. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage. Cisco has not released software updates to address these vulnerabilities.
