CVE-2025-8757 is a high-severity vulnerability affecting the TRENDnet TV-IP110WN IP camera, specifically version 1.2.2. The flaw resides in the embedded Boa web server component, particularly within the /server/boa.conf configuration file. This vulnerability leads to a least privilege violation, meaning that an attacker with limited local privileges could potentially escalate their access rights beyond what is intended. The attack requires local access to the device, which significantly limits the attack surface to those who can physically or logically access the device's local environment. The complexity of exploiting this vulnerability is high, indicating that it is not trivial to leverage this flaw successfully. Additionally, the exploit does not require user interaction but does require the attacker to have at least low privileges on the device. The vulnerability impacts confidentiality, integrity, and availability at a high level, as indicated by the CVSS 4.0 vector (AV:L/AC:H/PR:L/UI:N/VC:H/VI:H/VA:H). The vendor has been notified but has not responded or provided a patch, and no known exploits are currently observed in the wild. This lack of vendor response and patch availability increases the risk for affected users. The embedded Boa web server is a lightweight HTTP server commonly used in embedded devices, and misconfigurations or vulnerabilities in its configuration files can lead to privilege escalation or unauthorized access. Given the nature of the device (an IP camera), exploitation could allow attackers to gain unauthorized control over the camera, access video streams, or pivot to other network resources.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on TRENDnet TV-IP110WN cameras for security surveillance in sensitive environments such as offices, warehouses, or critical infrastructure sites. An attacker exploiting this vulnerability could escalate privileges locally on the device, potentially gaining control over the camera's functions, intercepting or manipulating video feeds, or using the compromised device as a foothold to move laterally within the internal network. This could lead to breaches of confidentiality (unauthorized video surveillance), integrity (tampering with camera settings or footage), and availability (disabling the camera). Given the high complexity and local access requirement, the threat is more relevant to insider threats or attackers who have already gained some form of access to the internal network or physical premises. However, the absence of a vendor patch and public exploit disclosure increases the risk that skilled attackers could develop effective exploits, raising the urgency for mitigation. European organizations with compliance obligations under GDPR must also consider the privacy implications of unauthorized access to surveillance data, which could lead to regulatory penalties and reputational damage.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately inventory and identify all TRENDnet TV-IP110WN devices running firmware version 1.2.2 within their environment. 2) Restrict physical and network access to these devices to trusted personnel only, implementing strict access controls and network segmentation to isolate IP cameras from critical network segments. 3) Disable or limit local access interfaces where possible, such as direct console or SSH access, to reduce the risk of local exploitation. 4) Monitor device logs and network traffic for unusual activities that could indicate attempts to exploit this vulnerability or unauthorized access. 5) If feasible, replace affected devices with newer models or alternative products that do not have this vulnerability or have active vendor support and patching. 6) Engage with TRENDnet or authorized resellers to seek firmware updates or official patches, and consider reporting the lack of vendor response to relevant cybersecurity authorities or CERTs. 7) Implement compensating controls such as multi-factor authentication for device management interfaces and ensure that default credentials are changed. 8) Educate internal staff about the risks of insider threats and the importance of securing physical access to IP cameras.
