JAWS Webserver RCE in MVPower CCTV DVR

IdentifiersCVE-2016-20016CWE-78· Improper Neutralization of Special…

MVPower CCTV DVR devices, including models such as TV-7104HE firmware 1.8.4 115215B9 and TV7108HE, contain an exposed web shell reachable via the /shell URI on the embedded JAWS web server. The endpoint allows a remote, unauthenticated attacker to supply arbitrary operating system commands, which are executed by the device as root. The issue is effectively a built-in backdoor/command-execution interface exposed over HTTP and has been widely referred to as the "JAWS webserver RCE." Reporting indicates that additional firmware versions from at least 2014 through 2019 may also be affected.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation results in full remote compromise of the DVR with root-level command execution. An attacker can execute arbitrary shell commands, deploy malware or botnet payloads, alter device configuration, disable or evade monitoring, pivot within the local network, and use the device for persistence or DDoS activity. The vulnerability has been reported as exploited in the wild from 2017 through 2022.

Mitigation

If you can’t patch tonight, do this now.

Immediately block external access to the DVR web interface, especially the /shell URI, using firewall rules, ACLs, or upstream filtering. Place affected devices behind VPN-only administrative access or on isolated management networks. Disable or decommission affected internet-facing DVRs where patching is not possible. Monitor for HTTP requests to /shell and for suspicious outbound command retrieval activity such as wget/curl-based payload downloads, and inspect devices for signs of botnet infection or unauthorized root-level changes.

Remediation

Patch, then assume compromise.

Upgrade to vendor-fixed firmware if an updated image is available for the affected MVPower/OEM device model. If no supported fix exists, replace the device with a supported product, as many affected DVRs are legacy or OEM-rebranded systems with poor patch availability. Remove direct internet exposure of the management/web interface and verify that any exposed /shell endpoint is no longer reachable after remediation.
