Cisco Small Business RV Series VPN Multiple RCE (cisco-sa-rv160-260-rce-XZeFkNHf)

critical Nessus Plugin ID 146268


The remote device is missing a vendor-supplied security patch.


According to its self-reported version, Cisco Small Business RV Series Router Firmware is affected by multiple remote code execution (RCE) vulnerabilities in the web-based management interface due to improper validation of HTTP requests. An unauthenticated, remote attacker could exploit this by sending a crafted HTTP request to the web-based management to execute arbitrary code as the root user on an affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade to the relevant fixed version referenced in Cisco bug IDs CSCvw13908, CSCvw13917, CSCvw19718, CSCvw19849, CSCvw27923, CSCvw27982, CSCvw50568
