Description

MVPower CCTV DVR models, including TV-7104HE 1.8.4 115215B9 and TV7108HE, contain a web shell that is accessible via a /shell URI. A remote unauthenticated attacker can execute arbitrary operating system commands as root. This vulnerability has also been referred to as the "JAWS webserver RCE" because of the easily identifying HTTP response server field. Other firmware versions, at least from 2014 through 2019, can be affected. This was exploited in the wild in 2017 through 2022.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
