AVTECH IP Camera/NVR/DVR PwdGrp.cgi command injection
|CVSS Meta Temp Score|
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
|Current Exploit Price (≈)|
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
|CTI Interest Score|
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.
A vulnerability was found in AVTECH IP Camera, NVR and DVR (Network Camera Software) (the affected version unknown). It has been declared as very critical. This vulnerability affects an unknown part of the file /cgi-bin/supervisor/PwdGrp.cgi. The manipulation with an unknown input leads to a command injection vulnerability. The CWE definition for the vulnerability is CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability.
The weakness was released 10/11/2016 by Gergely Eberhardt (ebux25) as AVTECH IP Camera, NVR, DVR multiple vulnerabilities as not defined mailinglist post (Bugtraq). The advisory is shared for download at seclists.org. The mailinglist post contains:
We note that the above vulnerabilities were found within a short period of time without a systematic approach. Based on the vulnerability types we found and the overall code quality, the devices should contain much more problems.The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details and also a private exploit are known. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 05/18/2019). The MITRE ATT&CK project declares the attack technique as T1202.
It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 358 days. During that time the estimated underground price was around $5k-$25k. A worm is spreading, which is automatically exploiting this vulnerability.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
