CVE-2025-55810 is a vulnerability identified in the Alaga Home Security WiFi Camera 3K, specifically model S-CW2503C-H with hardware version V03 and firmware version 1.4.2. The flaw allows an attacker with physical access to the device to execute arbitrary commands with root privileges by inserting a script file with a specific filename onto an SD card used by the camera. This vulnerability is categorized under CWE-434, which relates to improper handling of uploaded files, indicating that the device improperly processes or executes files from external storage without sufficient validation or restrictions. The attack vector is physical (AV:P), requiring no authentication (PR:N) or user interaction (UI:N), making it easier for an attacker who gains physical access to the device to exploit it. The impact is high across confidentiality, integrity, and availability, as root command execution can lead to full device compromise, data exfiltration, or device disruption. The CVSS v3.1 base score is 6.8, reflecting medium severity due to the physical access requirement limiting remote exploitation. No patches or mitigations have been published yet, and no known exploits are reported in the wild. This vulnerability highlights the risk of physical attack vectors on IoT devices that rely on external storage and insufficient input validation.

For European organizations, especially those deploying Alaga Home Security WiFi Camera 3K devices in sensitive or critical environments such as offices, retail, or industrial sites, this vulnerability poses a significant risk. An attacker with physical access could gain root control, potentially compromising video feeds, accessing stored data, or using the device as a foothold into the internal network. This could lead to breaches of confidentiality, manipulation or deletion of video evidence, and disruption of security monitoring capabilities. The physical access requirement limits the scope to insiders, visitors, or intruders who can reach the device, but the impact of such an attack could be severe. Organizations relying on these cameras for perimeter or internal security should be aware of the risk of unauthorized command execution and potential lateral movement within their networks. The absence of patches increases exposure until a fix is released.

1. Restrict physical access to the cameras by installing them in secure, tamper-resistant locations or enclosures to prevent unauthorized insertion of SD cards. 2. Monitor physical security logs and conduct regular inspections of devices to detect any unauthorized access or tampering. 3. Disable or remove SD card functionality if not required for operation to eliminate the attack vector. 4. Implement network segmentation to isolate IoT devices from critical infrastructure and sensitive data networks, limiting lateral movement if compromise occurs. 5. Once available, promptly apply firmware updates or patches from the vendor addressing this vulnerability. 6. Employ endpoint detection and response solutions capable of monitoring unusual device behavior or command execution patterns. 7. Educate staff about the risks of physical device tampering and enforce strict access control policies. 8. Consider alternative security camera solutions with stronger physical and software security controls if risk tolerance is low.
