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
- →Exploit vector targets the web-based management interface of affected Cisco Small Business RV160/RV260 series routers via crafted HTTP requests sent by an unauthenticated remote attacker ↗
- →No authentication is required to exploit; monitor web management interface (typically HTTPS on port 443) for anomalous or malformed HTTP requests from external/untrusted sources on affected device models: RV160, RV160W, RV260, RV260P, RV260W ↗
- ·Three distinct Cisco bug IDs are tracked under this advisory (CSCvw13908, CSCvw13917, CSCvw19718), indicating multiple separate code paths are vulnerable; patching must address all three ↗
- ·Root cause is improper validation of HTTP requests (CWE-472); ensure web management interface is not exposed to untrusted networks as a compensating control ↗
