Cisco Small Business RV Series - Remote Code Execution (CVE-2021-1472)

The Cisco server is vulnerable to CVE-2021-1472, a Remote Code Execution vulnerability, affecting the /upload endpoint. The root cause of this vulnerability exists because the device does not adequately verify the credentials in the HTTP Authorization field when requests are made to the /upload endpoint. An attacker simply has to pass any generic Authorization header as part of the request to bypass the authorization check.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

Upgrade Cisco to the latest version.
