CVE-2025-9936 is a medium-severity vulnerability identified in version 1.0.0 of the fuyang_lipengjun platform, specifically affecting the AdController component within the /ad/queryAll endpoint. The vulnerability stems from improper authorization controls, allowing an attacker to remotely access functionality or data that should be restricted. The vulnerability does not require user interaction or prior authentication, making it remotely exploitable over the network with low attack complexity. The CVSS 4.0 vector indicates no privileges or user interaction are needed, and the impact is limited to confidentiality with low impact on integrity and availability. While no patches or fixes are currently linked, a public exploit is available, increasing the risk of exploitation. The improper authorization likely allows unauthorized users to query or retrieve advertisement-related data or configurations, potentially exposing sensitive business information or enabling further attacks. The vulnerability's scope is limited to the affected platform version 1.0.0, and no known exploits in the wild have been reported yet. However, the availability of a public exploit means attackers could leverage this vulnerability for reconnaissance or data leakage remotely without authentication.

For European organizations using the fuyang_lipengjun platform version 1.0.0, this vulnerability could lead to unauthorized disclosure of sensitive advertising or operational data. This could impact confidentiality, potentially revealing strategic marketing information or user data tied to advertisements. While the direct impact on system integrity and availability is low, the exposure of internal data could facilitate further targeted attacks or competitive intelligence gathering. Organizations in sectors relying heavily on digital advertising platforms, such as e-commerce, media, and marketing agencies, could face reputational damage or regulatory scrutiny if personal data is exposed. Given the remote exploitability without authentication, attackers could scan and target vulnerable instances across Europe, increasing the risk of widespread data leakage. The lack of patches means organizations must rely on compensating controls until a fix is available, increasing operational risk.

European organizations should immediately audit their deployment of the fuyang_lipengjun platform to identify any instances running version 1.0.0. Until an official patch is released, organizations should implement strict network-level access controls to restrict access to the /ad/queryAll endpoint, limiting it to trusted internal IPs or VPN users only. Web application firewalls (WAFs) should be configured to detect and block anomalous requests targeting this endpoint, especially those attempting to bypass authorization. Monitoring and logging access to the AdController functionality should be enhanced to detect suspicious activity indicative of exploitation attempts. Organizations should also engage with the vendor or community to obtain or develop patches or workarounds to enforce proper authorization checks. Regular vulnerability scanning and penetration testing should include checks for this vulnerability. Finally, educating security teams about this vulnerability and the availability of public exploits will help in early detection and response.
