CVE-2025-11851 identifies a cross-site scripting (XSS) vulnerability in the Apeman ID71 device firmware version EN75.8.53.20. The vulnerability resides in an unspecified function within the /set_alias.cgi endpoint, where the alias parameter is not properly sanitized or encoded, allowing an attacker to inject malicious JavaScript code. This flaw can be exploited remotely without requiring authentication, although user interaction is necessary, typically by tricking a user into visiting a crafted URL containing the malicious payload. The vulnerability impacts the confidentiality and integrity of user sessions by enabling script execution in the victim’s browser context, which can lead to session hijacking, credential theft, or redirection to malicious sites. The vendor was notified early but has not issued a patch or mitigation guidance, and no public exploits have been confirmed in the wild yet. The CVSS 4.0 score of 5.1 reflects a medium severity, considering the ease of remote exploitation, lack of authentication, but requirement for user interaction and limited impact on system availability. This vulnerability is particularly concerning for environments where the Apeman ID71 is used in security-sensitive roles, such as surveillance or access control, as attackers could leverage XSS to escalate attacks or disrupt operations. The absence of vendor response increases the urgency for organizations to implement compensating controls and monitor for exploitation attempts.

For European organizations, the impact of CVE-2025-11851 could be significant in sectors relying on Apeman ID71 devices, such as physical security, surveillance, or access management. Successful exploitation could lead to unauthorized access to user sessions, enabling attackers to perform actions on behalf of legitimate users or steal sensitive information. This could compromise the integrity of security systems, potentially allowing attackers to bypass controls or manipulate device configurations. Additionally, XSS attacks can serve as a vector for delivering further malware or phishing campaigns targeting employees or administrators. The lack of vendor patches means organizations must rely on network-level protections and user awareness to mitigate risk. Disruption or compromise of security devices could have cascading effects on operational continuity and regulatory compliance, especially under GDPR and other European data protection frameworks. The medium severity rating suggests a moderate but tangible risk that should not be ignored, particularly in critical infrastructure or high-value environments.

1. Restrict network access to the /set_alias.cgi endpoint by implementing firewall rules or network segmentation to limit exposure only to trusted management networks. 2. Deploy web application firewalls (WAFs) with robust XSS detection and blocking capabilities to intercept malicious payloads targeting the alias parameter. 3. Educate users and administrators about the risks of clicking on unsolicited or suspicious links that could trigger XSS attacks. 4. Monitor device logs and network traffic for unusual requests or patterns indicative of exploitation attempts. 5. If possible, disable or restrict the functionality of the vulnerable endpoint until a vendor patch is available. 6. Consider deploying reverse proxies or security gateways that can sanitize input parameters before forwarding requests to the device. 7. Maintain an inventory of all Apeman ID71 devices and prioritize patching or replacement plans once vendor updates are released. 8. Engage with Apeman support channels persistently to seek official remediation or guidance. 9. Implement multi-factor authentication and strong session management on management interfaces to reduce the impact of session hijacking. 10. Regularly review and update incident response plans to include scenarios involving XSS exploitation on security devices.
