Executive Summary

This vulnerability affects the FNKvision Y215 CCTV Camera, where user passwords are stored using a weak DES-based crypt() hashing algorithm in the /etc/passwd file. Because DES-based hashes are outdated and weak, attackers with local access can quickly crack these hashes through brute-force attacks, especially given the limited password space. This allows them to recover passwords rapidly and potentially gain unauthorized access to the device. [1, 2]

Impact Analysis

If exploited, this vulnerability can lead to unauthorized access to the FNKvision Y215 CCTV Camera due to rapid password recovery from weak hashes. Although exploitation requires local access and is considered difficult, once compromised, an attacker could potentially control or manipulate the device, impacting security and privacy. [1, 2]

Detection Guidance

This vulnerability can be detected by inspecting the /etc/passwd file on the FNKvision Y215 CCTV Camera device to check if the stored password hashes use the weak DES-based crypt() algorithm. Since exploitation requires local access, detection involves accessing the device locally and examining the password hashes. A command such as `cat /etc/passwd` can be used to view the password entries. Additionally, tools that analyze password hash strength can be used to identify DES-based hashes. There are no specific network detection commands since the attack is local only. [1, 2]

Mitigation Strategies

Immediate mitigation steps include restricting local access to the FNKvision Y215 CCTV Camera to trusted personnel only, as exploitation requires local environment access. Since no patches or vendor mitigations are available and the vendor did not respond, it is recommended to consider replacing the affected device with a more secure alternative. Monitoring for any suspicious local activity is also advised. [2]
