CVE-2025-52392 identifies a security vulnerability in Soosyze CMS version 2.0, specifically related to its /user/login endpoint. The vulnerability arises from the absence of rate-limiting and account lockout mechanisms, which are critical controls designed to prevent brute-force attacks. Brute-force attacks involve an attacker systematically attempting numerous username and password combinations to gain unauthorized access. Without restrictions on the number or frequency of login attempts, an attacker can repeatedly submit credentials without triggering any defensive response from the system. This vulnerability is classified under CWE-307: Improper Restriction of Excessive Authentication Attempts, highlighting a failure to implement adequate controls to limit authentication attempts. The lack of these controls significantly increases the risk that an attacker could eventually guess valid credentials, potentially gaining administrative access to the CMS. Administrative access would allow the attacker to manipulate website content, inject malicious code, exfiltrate sensitive data, or pivot to other parts of the network. Although no known exploits are currently reported in the wild, the simplicity of the attack vector and the absence of mitigating controls make this vulnerability a serious concern. No CVSS score has been assigned yet, and no patches or fixes have been linked, indicating that organizations using Soosyze CMS 2.0 need to proactively address this issue to prevent exploitation.

For European organizations utilizing Soosyze CMS 2.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their web platforms. Unauthorized administrative access could lead to defacement of websites, unauthorized data disclosure including personal data protected under GDPR, and disruption of services. Given the CMS's role in managing web content, exploitation could also facilitate the distribution of malware or phishing content to end users, damaging organizational reputation and trust. The absence of rate-limiting increases the likelihood of successful brute-force attacks, especially if weak or reused passwords are in use. This threat is particularly impactful for sectors with high regulatory scrutiny such as finance, healthcare, and government entities within Europe, where data breaches can result in substantial fines and legal consequences. Additionally, the potential for lateral movement after initial compromise could expose broader enterprise networks to risk. The lack of known exploits currently provides a window for mitigation, but the ease of exploitation means that attackers could develop automated tools rapidly, increasing the threat level.

European organizations should implement several targeted measures beyond generic advice to mitigate this vulnerability effectively. First, immediate deployment of custom rate-limiting controls on the /user/login endpoint is critical; this can be achieved via web application firewalls (WAFs) or reverse proxies that throttle repeated login attempts from the same IP or user account. Second, implement account lockout policies that temporarily disable accounts after a defined number of failed login attempts to prevent continuous brute-force attempts. Third, enforce strong password policies and encourage or mandate multi-factor authentication (MFA) for all administrative accounts to reduce the risk of credential compromise. Fourth, monitor login attempts and set up alerts for unusual authentication patterns indicative of brute-force activity. Fifth, if possible, update or patch Soosyze CMS once the vendor releases a fix; meanwhile, consider isolating the CMS environment and restricting access to trusted IP ranges. Lastly, conduct regular security audits and penetration testing focused on authentication mechanisms to identify and remediate weaknesses proactively.
