CVE-2025-34052: CWE-200 Exposure of Sensitive Information to an Unauthorized Actor in AVTECH IP cameras
An unauthenticated information disclosure vulnerability exists in AVTECH IP cameras, DVRs, and NVRs via Machine.cgi?action=get_capability. Sensitive internal device information such as firmware version, MAC address, and codec support can be accessed without authentication.
AI Analysis
Technical Summary
CVE-2025-34052 is an information disclosure vulnerability affecting AVTECH IP cameras, DVRs, and NVRs. The vulnerability arises from an unauthenticated endpoint accessible via the URL parameter Machine.cgi?action=get_capability. This endpoint returns sensitive internal device information such as the firmware version, MAC address, and codec support without requiring any authentication or user interaction. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and CWE-306 (Missing Authentication for Critical Function). The CVSS v4.0 base score is 6.9, indicating a medium severity level. The attack vector is network-based with no privileges or user interaction required, making it relatively easy to exploit remotely. Although the disclosed information does not directly allow control over the device, it can facilitate further targeted attacks such as fingerprinting, identifying vulnerable firmware versions, or crafting device-specific exploits. The lack of authentication on this endpoint represents a significant security oversight, potentially exposing internal device details to any unauthenticated attacker scanning networks or the internet for AVTECH devices. No patches or known exploits are currently reported, but the vulnerability's public disclosure increases the risk of exploitation over time.
Potential Impact
For European organizations deploying AVTECH IP cameras and related devices, this vulnerability can lead to increased exposure of sensitive device information. Attackers can leverage the disclosed firmware versions and MAC addresses to identify vulnerable devices and launch more sophisticated attacks such as firmware exploitation, unauthorized access, or network reconnaissance. This is particularly concerning for critical infrastructure, government facilities, and enterprises relying on AVTECH devices for surveillance and security. The exposure of codec support details may also aid attackers in crafting denial-of-service or evasion techniques. While the vulnerability does not directly compromise device integrity or availability, it lowers the security posture and increases the attack surface, potentially facilitating lateral movement or escalation in targeted attacks. Given the widespread use of IP cameras in European public and private sectors, the risk of privacy violations and operational disruptions is non-negligible.
Mitigation Recommendations
1. Network Segmentation: Isolate AVTECH IP cameras and related devices on dedicated VLANs or network segments with strict access controls to limit exposure to untrusted networks. 2. Access Control: Implement firewall rules to restrict access to device management interfaces, allowing only trusted management stations or IP ranges. 3. Device Hardening: Disable or restrict access to the Machine.cgi endpoint if possible, or configure devices to require authentication for all management functions. 4. Firmware Updates: Monitor AVTECH vendor announcements for patches addressing this vulnerability and apply updates promptly once available. 5. Network Monitoring: Deploy intrusion detection/prevention systems to detect and alert on suspicious requests targeting the vulnerable endpoint. 6. Asset Inventory: Maintain an accurate inventory of AVTECH devices to quickly identify and remediate vulnerable units. 7. Vendor Engagement: Engage with AVTECH support to request security patches or mitigation guidance. 8. Incident Response Preparedness: Prepare response plans for potential exploitation scenarios involving AVTECH devices to minimize impact.
