CVE-2025-34050 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the web interface of AVTECH IP cameras, DVRs, and NVRs. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a vulnerable web application without their knowledge or consent. In this case, the vulnerability allows an attacker to craft malicious HTTP requests that, when executed in the context of an authenticated user's browser session, can cause unauthorized changes to the device's configuration. This means that if a user is logged into the AVTECH device's web interface, an attacker can exploit this flaw by luring the user to visit a malicious website or click a crafted link, which then silently sends unauthorized commands to the device. The vulnerability does not require the attacker to have any privileges or prior authentication (AV:N, PR:N), but it does require user interaction (UI:A), such as visiting a malicious webpage. The impact on confidentiality is none, but there is a low impact on integrity since device configurations can be altered, potentially affecting device behavior or security settings. Availability is not impacted. The CVSS 4.0 base score is 5.1, indicating a medium severity level. There are no known exploits in the wild yet, and no patches have been linked at the time of publication. The affected versions are not explicitly detailed beyond version '0', which may indicate all current versions or an unspecified range. The vulnerability stems from a lack of proper anti-CSRF protections in the device's web interface, such as missing or ineffective CSRF tokens or validation mechanisms. This flaw could allow attackers to manipulate device settings remotely by leveraging the victim's authenticated session, potentially leading to unauthorized access, surveillance manipulation, or disabling of security features.

For European organizations, especially those relying on AVTECH IP cameras and related devices for physical security and surveillance, this vulnerability poses a significant risk. Unauthorized configuration changes could disable or alter camera functions, degrade security monitoring, or open backdoors for further exploitation. This is particularly critical for sectors such as government facilities, critical infrastructure, transportation hubs, and corporate environments where surveillance integrity is paramount. Compromised devices could lead to blind spots in security coverage or unauthorized data exposure. Since the attack requires user interaction but no authentication or privileges, social engineering campaigns targeting employees or administrators could be effective. The medium severity rating suggests that while the vulnerability is not immediately catastrophic, it can facilitate further attacks or security breaches if exploited. The lack of patches increases the risk window. European organizations with remote or web-accessible AVTECH devices are especially vulnerable, as attackers can exploit the flaw without direct network access to the device.

1. Immediate mitigation should include restricting web interface access to trusted networks only, using network segmentation and firewall rules to limit exposure. 2. Disable remote web management if not strictly necessary, or enforce VPN access for remote administration to reduce attack surface. 3. Implement strict browser security policies and educate users to avoid clicking on suspicious links or visiting untrusted websites while logged into device interfaces. 4. Monitor device configurations regularly for unauthorized changes using automated tools or manual audits. 5. If possible, apply any vendor-provided patches or firmware updates as soon as they become available. 6. Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) that can detect and block CSRF attack patterns targeting these devices. 7. Advocate with AVTECH for timely release of patches and improved security controls such as CSRF tokens and session management enhancements. 8. Consider replacing vulnerable devices with alternatives that follow secure development practices if patches are delayed or unavailable.
