AVTECH AVC798HA DVR Detection Scanner

AVTECH AVC798HA DVR is a digital video recorder commonly used in security setups to manage and record video footage from surveillance cameras. It is frequently utilized by businesses, governmental institutions, and households aiming to enhance their security systems. This DVR is known for its reliable functionality and is employed by entities requiring continuous monitoring and recording capabilities. The AVTECH AVC798HA DVR is generally operated by security personnel or system administrators responsible for managing security infrastructures. Its purpose extends beyond simple video recording to include remote viewing and control features that are essential in modern security practices. With its robust construction, it's apt for both small and large scale security operations, making it a versatile component in integrated security solutions.

The vulnerability detected in the AVTECH AVC798HA DVR involves information exposure due to accessible CGI scripts in the /cgi-bin/nobody directory. These scripts can be accessed without proper authentication controls, allowing unauthorized users to potentially gain sensitive information. Such vulnerabilities lead to breaches of confidential data, making unauthorized operations not just possible, but easy for attackers. This vulnerability is classified under security misconfiguration, indicating improper setup that violates security policies. Unchecked, this opens avenues for attackers to exploit weaknesses in the system to their advantage. It underscores the necessity for thorough authentication and access controls to mitigate potential security risks.

Technical aspects of the vulnerability include exploit scenarios whereby attackers access CGI scripts designed to retrieve capabilities from the DVR. The vulnerable endpoint is identified as /cgi-bin/nobody/Machine.cgi?action=get_capability, which, when accessed, provides information like firmware version, MAC addresses, and product types. Such data can be detrimental if leveraged by a malicious entity to bypass standard security practices. The template conditions specifically seek a successful HTTP 200 response and tailored keywords that identify exposed information types. This inadequacy in restricted access highlights critical lapses that need redressing in the device's deployment environments.

Possible effects of exploiting this vulnerability range from unauthorized data access and modification to complete operational compromise of the security system. Malicious actors exploiting these opened avenues could execute unapproved commands, manipulate video feed recordings, or sabotage the system's recording integrity. Apart from data loss, there could be severe reputational and financial repercussions resulting from breaches in security. Hence, it is essential for organizations using these DVRs to address the known vulnerabilities promptly and ensure all configurations are securely managed to prevent unauthorized exposure.
