Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers could allow an unauthenticated, remote attacker to execute arbitrary code as the root user on an affected device. These vulnerabilities exist because HTTP requests are not properly validated. An attacker could exploit these vulnerabilities by sending a crafted HTTP request to the web-based management interface of an affected device. A successful exploit could allow the attacker to remotely execute arbitrary code on the device.

Detection & IOCsextracted from sources · hover to see the quote

  • Attack vector is unauthenticated crafted HTTP requests to the web-based management interface of affected Cisco Small Business RV160/RV160W/RV260/RV260P/RV260W VPN Routers
  • Vulnerability class is improper HTTP request validation (CWE-472); inspect HTTP requests to the management interface for anomalous or malformed inputs
  • ·Multiple CVEs share the same advisory and bug IDs (CSCvw13908, CSCvw13917, CSCvw19718); ensure detections are scoped to CVE-2021-1289 specifically and not conflated with sibling vulnerabilities in the same advisory
  • ·Affected devices are Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers only; detections should be scoped to these device families
