CVE-2025-62120 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Rick Beckman OpenHook product, affecting all versions up to 4.3.1. CSRF vulnerabilities occur when a web application does not sufficiently verify that requests made to it originate from legitimate users, allowing attackers to craft malicious web pages or links that cause authenticated users to unknowingly perform actions on the vulnerable application. In this case, the vulnerability allows attackers to induce users to submit unauthorized requests that can alter application state or trigger actions without the user's explicit consent. The CVSS 3.1 base score of 5.4 reflects a medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no confidentiality impact (C:N), low integrity impact (I:L), and low availability impact (A:L). This means the attack can be launched remotely without credentials but requires the user to interact with a malicious link or site. The vulnerability does not impact confidentiality but can affect integrity and availability to a limited extent. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. OpenHook is a product used to extend or customize web applications, and its compromise could lead to unauthorized state changes or disruptions in web services.

For European organizations, the impact of CVE-2025-62120 depends largely on the extent of OpenHook deployment within their web infrastructure. Since the vulnerability allows attackers to perform unauthorized actions via CSRF, it can lead to unauthorized changes in application state, potentially disrupting business processes or causing denial of service conditions. The lack of confidentiality impact reduces the risk of data leakage, but integrity and availability impacts, though low, can still affect operational reliability. Organizations in sectors with high reliance on web applications, such as finance, government, and critical infrastructure, may face operational disruptions or reputational damage if exploited. The requirement for user interaction limits automated exploitation but does not eliminate risk, especially in environments with high user exposure to external content. The absence of known exploits provides a window for mitigation, but the public disclosure increases the risk of future exploitation attempts.

To mitigate CVE-2025-62120, European organizations should implement several targeted measures beyond generic advice: 1) Apply any forthcoming official patches or updates from Rick Beckman promptly once available. 2) Implement anti-CSRF tokens in all state-changing requests within OpenHook-integrated applications to ensure requests originate from legitimate sources. 3) Enforce strict validation of the HTTP Referer and Origin headers to block unauthorized cross-origin requests. 4) Restrict sensitive operations to POST requests and avoid using GET requests for state changes. 5) Employ Content Security Policy (CSP) headers to reduce the risk of malicious content injection. 6) Educate users about the risks of clicking untrusted links or visiting suspicious websites to reduce user interaction risk. 7) Conduct regular security audits and penetration testing focusing on CSRF and related web vulnerabilities in applications using OpenHook. 8) Monitor web application logs for unusual or unauthorized request patterns that may indicate exploitation attempts.
