Multiple vulnerabilities in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, RV130 VPN Router, RV130W Wireless-N Multifunction VPN Router, and RV215W Wireless-N VPN Router could allow an authenticated, remote attacker to execute arbitrary code on an affected device. The vulnerabilities are due to improper validation of user-supplied data in the web-based management interface. An attacker could exploit these vulnerabilities by sending malicious HTTP requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system of the affected device as a high-privilege user.

Detection & IOCsextracted from sources · hover to see the quote

  • Exploit vector is malicious HTTP requests sent to the web-based management interface of affected Cisco RV110W, RV130, RV130W, and RV215W routers; monitor for anomalous or malformed HTTP requests targeting these devices' management interfaces.
  • Successful exploitation results in arbitrary code execution as a high-privilege user on the underlying OS; monitor for unexpected process spawning or privilege escalation on affected router platforms.
  • Root cause is improper validation of user-supplied data in the web-based management interface (CWE-119 buffer overflow/memory corruption); look for oversized or malformed input fields in HTTP POST/GET requests to the management interface.
  • Track Cisco Bug IDs CSCvr94660, CSCvr96222, and CSCvr96225 for patch status and additional technical details related to this CVE cluster.
  • ·Exploitation requires prior authentication; unauthenticated attackers cannot directly exploit this vulnerability without valid credentials to the management interface.
  • ·No workarounds are available; the only mitigation is applying the vendor-supplied software update.
