Attack-Flow Graph

Executive Summary

This vulnerability involves a legacy password hash on the serial console of Anjvision YSSD-RTMP-H5 firmware version 3.3.2.4. The password hash uses weak DES-based encryption, which is outdated and easily crackable, allowing unauthorized access to the device.

Detection Guidance

This vulnerability involves a weak DES-based password hash on the serial console of Anjvision YSSD-RTMP-H5 firmware version 3.3.2.4. Detection requires checking the firmware version and inspecting the serial console for legacy password hashes using device-specific tools or commands.

Impact Analysis

An attacker could exploit this vulnerability to gain unauthorized access to the device via the serial console. This could lead to full control over the device, potential data theft, or disruption of services relying on the device.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating confidentiality requirements in GDPR and HIPAA. Organizations may face legal penalties, reputational damage, and loss of compliance certifications.

Mitigation Strategies

Immediately update the firmware to a patched version if available. Disable or restrict access to the serial console interface. Replace any legacy DES-based password hashes with stronger encryption methods. Monitor network traffic for unauthorized access attempts.
