CVE-2025-6561: CWE-497 Exposure of Sensitive System Information to an Unauthorized Control Sphere in Hunt Electronic HBF-09KD
Certain hybrid DVR models ((HBF-09KD and HBF-16NK)) from Hunt Electronic have an Exposure of Sensitive Information vulnerability, allowing unauthenticated remote attackers to directly access a system configuration file and obtain plaintext administrator credentials.
AI Analysis
Technical Summary
CVE-2025-6561 is a critical security vulnerability affecting certain hybrid DVR models (HBF-09KD and HBF-16NK) produced by Hunt Electronic. This vulnerability is classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere) and CWE-256 (Plaintext Storage of a Password). The flaw allows unauthenticated remote attackers to directly access a system configuration file on the affected devices. This file contains plaintext administrator credentials, which means that an attacker can obtain full administrative access without any prior authentication or user interaction. The vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and affects the confidentiality, integrity, and availability of the device (C:H/I:H/A:H). The CVSS v3.1 base score is 9.8, indicating a critical severity level. The exposure of plaintext administrator credentials can lead to complete compromise of the DVR devices, enabling attackers to manipulate video recordings, disable security monitoring, or use the devices as pivot points for further network intrusion. No patches or mitigations have been officially released at the time of this report, and no known exploits are currently observed in the wild. However, the ease of exploitation and the critical impact make this a high-priority vulnerability for affected organizations to address promptly.
Potential Impact
For European organizations, the impact of this vulnerability can be significant, especially for those relying on Hunt Electronic hybrid DVRs for physical security and surveillance. Compromise of these devices could lead to unauthorized access to surveillance footage, tampering with recorded evidence, or disabling of security monitoring systems, which may result in undetected physical breaches or data theft. Organizations in sectors such as critical infrastructure, transportation, government facilities, and large enterprises that use these DVRs for security monitoring are particularly at risk. Furthermore, attackers gaining control over these devices could use them as entry points into internal networks, potentially leading to broader cyber intrusions. The exposure of administrator credentials without authentication requirements increases the risk of widespread exploitation. This could also affect compliance with European data protection regulations (e.g., GDPR) if surveillance data is compromised or manipulated.
Mitigation Recommendations
1. Immediate network segmentation: Isolate affected Hunt Electronic DVRs from the broader corporate network and restrict access to trusted management hosts only. 2. Implement strict firewall rules to block all unnecessary inbound and outbound traffic to these devices, especially from untrusted external networks. 3. Monitor network traffic for unusual access patterns or attempts to retrieve configuration files from the DVRs. 4. Change default administrator credentials on all affected devices if possible, and enforce strong password policies. 5. Disable remote management interfaces if not required or restrict them to VPN access only. 6. Engage with Hunt Electronic support or authorized vendors to obtain firmware updates or patches as soon as they become available. 7. Conduct regular security audits and vulnerability assessments on physical security devices to detect similar exposures. 8. Consider replacing affected DVR models with more secure alternatives if patching is not feasible in the short term. 9. Implement multi-factor authentication (MFA) on management interfaces if supported by the devices to add an additional layer of security.
