An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to gain root-level privileges and access unauthorized data. To exploit this vulnerability, an attacker would need to have valid administrative credentials on the affected device.\r\n\r Cisco has not and will not release software updates that address this vulnerability.   However, administrators may disable the affected feature as described in the Workarounds [\"#workarounds\"] section.\r\n\r  {{value}} [\"%7b%7bvalue%7d%7d\"])}]]","published":"2023-04-13T07:15:21.000Z","lastModified":"2026-06-17T05:29:31.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-77"],"affected":["cisco/rv016 firmware","cisco/rv042 firmware","cisco/rv042g firmware","cisco/rv082 firmware","cisco/rv320 firmware","cisco/rv325 firmware"],"epss":{"score":0.54107,"percentile":0.99005,"date":"2026-10-30","history":[]},"kev":{"listed":true,"dateAdded":"2025-03-03","dueDate":"2025-03-24","knownRansomwareCampaignUse":"Unknown","notes":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sbr042-multi-vuln-ej76Pke5 ; https://nvd.nist.gov/vuln/detail/CVE-2023-20118"},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 24 March 2025).
