CVE-2022-44389 is a Cross-Site Request Forgery (CSRF) vulnerability identified in EyouCMS version 1.5.9-UTF8-SP1, specifically within the Edit Admin Profile module. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, which the web application processes as a legitimate action. In this case, the vulnerability allows an attacker to manipulate the administrator's profile information without their consent or knowledge. Because the attack targets the administrator account, it can lead to unauthorized changes in critical account details, potentially enabling privilege escalation or persistent unauthorized access. The vulnerability requires the administrator to be authenticated and to interact with a maliciously crafted link or webpage (user interaction required). The CVSS 3.1 base score is 6.5 (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), high integrity impact (I:H), and no availability impact (A:N). No known exploits have been reported in the wild, and no official patches or vendor information are currently available. The vulnerability is classified under CWE-352, which covers CSRF weaknesses. Given that EyouCMS is a content management system, this vulnerability could be exploited to alter administrator credentials or settings, potentially compromising the entire CMS environment.

For European organizations using EyouCMS 1.5.9-UTF8-SP1, this vulnerability poses a significant risk to the integrity of their web management systems. Successful exploitation could allow attackers to change administrator profile information, such as passwords or email addresses, leading to unauthorized administrative access. This could result in website defacement, data manipulation, or the installation of backdoors, undermining the trustworthiness and availability of web services. Organizations in sectors with high reliance on web presence—such as e-commerce, government portals, and media—could face reputational damage and operational disruptions. Since the vulnerability requires user interaction and an authenticated administrator session, the risk is somewhat mitigated by the need for an administrator to be logged in and to interact with malicious content. However, targeted phishing campaigns or social engineering could facilitate exploitation. The lack of known exploits in the wild suggests limited current active exploitation, but the medium severity and potential impact on integrity warrant proactive measures.

European organizations should implement the following specific mitigations: 1) Immediately audit and monitor administrator account activities for unauthorized changes, focusing on profile modifications. 2) Enforce strict Content Security Policy (CSP) headers and SameSite cookie attributes to reduce CSRF attack vectors. 3) Implement or verify the presence of anti-CSRF tokens in all forms, especially those related to administrator profile editing, and ensure these tokens are validated server-side. 4) Educate administrators about phishing and social engineering risks to reduce the likelihood of user interaction with malicious content. 5) Restrict administrative access to trusted IP ranges or via VPN to limit exposure. 6) Regularly update or patch EyouCMS installations when vendor patches become available. 7) Consider deploying Web Application Firewalls (WAFs) with rules to detect and block CSRF attempts targeting the admin profile endpoints. 8) If feasible, disable or limit the use of the vulnerable module until a patch is released. These measures go beyond generic advice by focusing on specific controls tailored to the nature of the vulnerability and the affected CMS module.
