CVE-2017-3186 in Camera
Summary
by MITRE
ACTi cameras including the D, B, I, and E series using firmware version A1D-500-V6.11.31-AC use non-random default credentials across all devices. A remote attacker can take complete control of a device using default admin credentials.

The vulnerability identified as CVE-2017-3186 affects ACTi network video surveillance cameras across multiple series including D, B, I, and E models. These devices operate with firmware versions containing non-random default credentials that are consistently deployed across all affected units. The flaw represents a critical security weakness that directly impacts the device's authentication mechanism and overall security posture. This vulnerability specifically targets the administrative access controls of these surveillance devices, creating a significant risk for organizations relying on ACTi cameras for security monitoring.
The technical implementation of this vulnerability stems from the use of predictable and static default credentials across all affected devices within the specified firmware versions. The default administrative credentials are not randomly generated or dynamically configured, making them easily discoverable through publicly available information or simple enumeration techniques. This design flaw allows attackers to gain unauthorized administrative access to the camera systems without requiring specialized tools or advanced exploitation techniques. The vulnerability directly maps to CWE-798, which categorizes the use of hard-coded credentials as a significant security weakness, and aligns with ATT&CK technique T1078.101 which covers valid accounts with default passwords.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with complete administrative control over affected camera systems. Once compromised, attackers can manipulate video feeds, modify camera settings, disable security features, and potentially use the compromised devices as entry points for broader network attacks. The remote nature of this vulnerability means that attackers can exploit it from outside the network perimeter, eliminating the need for physical access or network infiltration. Organizations may experience unauthorized surveillance, data breaches, or the use of compromised cameras for malicious activities including reconnaissance or as part of larger attack campaigns.
Mitigation strategies for CVE-2017-3186 require immediate action to address the default credential exposure. Organizations should immediately change default administrative credentials to strong, unique passwords for all affected devices and ensure that these credentials are properly secured. Network segmentation should be implemented to isolate surveillance equipment from critical network segments, and regular security audits should be conducted to verify credential configurations. Device firmware should be updated to versions that address the default credential issue, and access controls should be configured to limit administrative privileges to only necessary personnel. The vulnerability highlights the importance of following security best practices including the principle of least privilege and regular credential rotation as outlined in industry standards such as NIST SP 800-123 and ISO/IEC 27001. Continuous monitoring of network devices and implementation of automated credential management systems can help prevent similar vulnerabilities from being exploited in the future.
