CVE-2025-62120 identifies a Cross-Site Request Forgery (CSRF) vulnerability in Rick Beckman OpenHook, a software product used for hooking or extending application functionality. The vulnerability exists in versions up to 4.3.1 and allows an attacker to induce an authenticated user to perform unwanted actions without their consent. CSRF attacks exploit the trust a web application places in the user's browser by sending forged HTTP requests that appear legitimate. In this case, the attacker does not require any privileges or authentication but does require the victim to interact with a malicious link or webpage (user interaction required). The CVSS 3.1 vector indicates the attack can be launched remotely over the network (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The impact affects integrity and availability, potentially allowing unauthorized commands or disruptions. No confidentiality impact is noted. No patches or exploit code are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The lack of patches means organizations must rely on mitigations until a fix is released. The vulnerability is categorized under CWE-352, which is a common web security weakness related to CSRF. Given the nature of OpenHook, which may be integrated into various applications or environments, the risk depends on deployment context and exposure.

For European organizations, the CSRF vulnerability in OpenHook could lead to unauthorized actions being executed on behalf of legitimate users, potentially disrupting business processes or altering data integrity. While confidentiality is not directly impacted, integrity and availability risks could affect operational stability, especially if OpenHook is used in critical workflows or automation. Attackers could exploit this vulnerability to cause denial of service or unauthorized configuration changes. The requirement for user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks, particularly phishing campaigns. Organizations in sectors with high reliance on web-based management or automation tools incorporating OpenHook may face increased risk. The absence of known exploits in the wild currently limits immediate threat but does not preclude future exploitation. The medium severity rating suggests a moderate priority for remediation, especially in environments with sensitive or critical operations.

To mitigate CVE-2025-62120, organizations should implement the following specific measures: 1) Deploy anti-CSRF tokens in all state-changing requests within OpenHook-integrated applications to ensure requests are legitimate. 2) Enforce strict validation of the HTTP Referer or Origin headers to block cross-origin requests. 3) Limit the exposure of OpenHook interfaces to trusted networks or VPNs to reduce attack surface. 4) Educate users about the risks of clicking unknown links or visiting untrusted websites to minimize user interaction exploitation. 5) Monitor logs for unusual or unexpected requests that could indicate attempted CSRF attacks. 6) Prepare for rapid deployment of vendor patches once available by maintaining an inventory of affected systems. 7) Consider implementing Content Security Policy (CSP) headers to restrict the sources of executable scripts and reduce attack vectors. 8) Review and harden session management to prevent session fixation or hijacking that could compound CSRF risks. These targeted actions go beyond generic advice by focusing on the specific nature of the OpenHook vulnerability and its exploitation requirements.
