The attacker must have either a valid credential or an active session token. The vulnerability is due to lack of input validation of the HTTP payload. An attacker could exploit this vulnerability by sending a malicious HTTP request to the web-based management interface of the targeted device. A successful exploit could allow the attacker to execute commands with root privileges.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","base_score":8.8,"base_severity":"HIGH","attack_vector":"NETWORK","privileges_req":"LOW","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-502"],"in_kev":true,"kev_date_added":"2022-06-08","kev_ransomware":false,"epss_score":0.05488,"epss_percentile":0.92777,"cap_rule_version":"0.1.1","stage":"EXECUTION","req_access":"USER","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T09:07:16.210213+00:00","first_seen":"2019-11-26T03:15:11.050000+00:00","kev_first_seen":"2022-06-08T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["cisco"],"products":["rv016_multi-wan_vpn","rv016_multi-wan_vpn_firmware","rv042_dual_wan_vpn","rv042_dual_wan_vpn_firmware","rv042g_dual_gigabit_wan_vpn","rv042g_dual_gigabit_wan_vpn_firmware","rv082_dual_wan_vpn","rv082_dual_wan_vpn_firmware"],"affected":[{"vendor":"cisco","product":"rv016_multi-wan_vpn_firmware","ranges":["< 4.2.3.10"]},{"vendor":"cisco","product":"rv042_dual_wan_vpn_firmware","ranges":["< 4.2.3.10"]},{"vendor":"cisco","product":"rv042g_dual_gigabit_wan_vpn_firmware","ranges":["< 4.2.3.10"]},{"vendor":"cisco","product":"rv082_dual_wan_vpn_firmware","ranges":["< 4.2.3.10"]}]}
