EUVD-2024-35291

Comprehensive Technical Analysis of EUVD-2024-35291

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2024-35291 affects certain Anpviz IP camera products, allowing unauthenticated users to download arbitrary files from the device's filesystem via an HTTP GET request to the /playback/ URI. This vulnerability is severe due to the following factors:

• Unauthenticated Access: The attacker does not need any credentials to exploit the vulnerability.
• High Impact: The vulnerability allows for the disclosure of sensitive information, potential integrity compromise, and availability disruption.
• Wide Scope: The vulnerability affects multiple models and firmware versions, indicating a broad attack surface.

The CVSS (Common Vulnerability Scoring System) base score of 9.8 (out of 10) underscores the critical nature of this vulnerability. The vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates:

• Attack Vector (AV:N): Network-based attack.
• Attack Complexity (AC:L): Low complexity required for exploitation.
• Privileges Required (PR:N): No privileges required.
• User Interaction (UI:N): No user interaction required.
• Scope (S:U): Unchanged.
• Confidentiality (C:H): High impact on confidentiality.
• Integrity (I:H): High impact on integrity.
• Availability (A:H): High impact on availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector involves sending an HTTP GET request to the /playback/ URI on the affected IP cameras. This can be done using standard HTTP tools or scripts. Potential exploitation methods include:

• Information Disclosure: Attackers can download configuration files, logs, and other sensitive data.
• Further Exploitation: Downloaded files may contain credentials or other sensitive information that can be used to gain further access to the network.
• Denial of Service (DoS): Attackers could potentially disrupt the camera's operation by repeatedly accessing critical files.

3. Affected Systems and Software Versions

The vulnerability affects the following Anpviz IP camera models with firmware version v3.2.2.2 and lower:

• IPC-D250, IPC-D260, IPC-B850, IPC-D850, IPC-D350, IPC-D3150, IPC-D4250, IPC-D380, IPC-D880, IPC-D280, IPC-D3180
• MC800N, YM500L, YM800N_N2, YMF50B, YM800SV2, YM500L8, YM200E10

Additionally, the entry suggests that other vendors/models of IP cameras might also be affected.

4. Recommended Mitigation Strategies

To mitigate this vulnerability, the following strategies are recommended:

• Firmware Update: Immediately update the firmware of affected devices to a version higher than v3.2.2.2, if available.
• Network Segmentation: Isolate IP cameras on a separate network segment to limit potential lateral movement by attackers.
• Access Control: Implement strict access controls and firewall rules to restrict unauthorized access to the IP cameras.
• Monitoring and Logging: Enable and monitor logging on the IP cameras to detect and respond to suspicious activities.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security issues.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to the European cybersecurity landscape, particularly in sectors that rely heavily on IP cameras for surveillance and security, such as:

• Critical Infrastructure: Power plants, transportation systems, and other critical infrastructure sites.
• Public Spaces: Airports, train stations, and other public areas.
• Private Sector: Businesses and organizations that use IP cameras for security and monitoring.

The widespread use of IP cameras and the potential for unauthenticated access make this vulnerability a high-priority concern for cybersecurity professionals in Europe.

6. Technical Details for Security Professionals

For security professionals, the following technical details are pertinent:

• Exploitation: The vulnerability can be exploited by sending an HTTP GET request to the /playback/ URI. For example:

  GET /playback/ HTTP/1.1
  Host: [IP_CAMERA_IP]
  

• Detection: Monitor network traffic for unusual HTTP GET requests to the /playback/ URI. Implement intrusion detection systems (IDS) to alert on such activities.
• Response: In case of detection, isolate the affected device immediately and perform a forensic analysis to determine the extent of the compromise.
• Patch Management: Ensure that all IP cameras are included in the organization's patch management program to receive timely updates.

By addressing this vulnerability promptly and comprehensively, organizations can significantly reduce the risk of exploitation and protect their critical assets.

Conclusion

EUVD-2024-35291 represents a critical vulnerability affecting multiple Anpviz IP camera models. The unauthenticated nature of the exploit and the high impact on confidentiality, integrity, and availability make it a top priority for cybersecurity professionals. Immediate mitigation strategies, including firmware updates, network segmentation, and strict access controls, are essential to safeguard against potential attacks.
