CVE-2025-52392 is a medium-severity vulnerability affecting Soosyze CMS version 2.0, specifically targeting the /user/login endpoint. The core issue is the absence of rate-limiting and account lockout mechanisms, which allows an attacker to perform brute-force login attempts without restriction. This vulnerability falls under CWE-307, which concerns improper restriction of excessive authentication attempts. Without these protections, an attacker can repeatedly submit login credentials to the login endpoint, increasing the likelihood of guessing valid administrative credentials and gaining unauthorized access. The vulnerability has a CVSS 3.1 base score of 5.4, reflecting a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R), with an impact on confidentiality and integrity but no impact on availability. The vulnerability does not currently have known exploits in the wild, and no patches or fixes have been published yet. The lack of rate-limiting and lockout mechanisms means that automated tools can be used to rapidly test large numbers of password combinations, potentially compromising administrative accounts and leading to unauthorized control over the CMS and its hosted content.

For European organizations using Soosyze CMS 2.0, this vulnerability poses a significant risk to the confidentiality and integrity of their web content and administrative controls. Unauthorized administrative access could lead to website defacement, data theft, insertion of malicious content, or use of the CMS as a pivot point for further network compromise. Given the CMS's role in managing web content, attacks could disrupt business operations, damage brand reputation, and lead to regulatory compliance issues, especially under GDPR if personal data is exposed or manipulated. The medium CVSS score indicates a moderate risk, but the ease of exploitation (no privileges required and low complexity) means attackers can attempt brute-force attacks remotely over the internet. This risk is heightened for organizations that do not implement additional protective controls such as web application firewalls or multi-factor authentication. Since no patches are currently available, organizations must rely on compensating controls to mitigate the threat.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Deploy web application firewalls (WAFs) with rules to detect and block brute-force login attempts targeting the /user/login endpoint, including rate-limiting based on IP address and request frequency. 2) Enforce multi-factor authentication (MFA) for all administrative accounts to reduce the risk of unauthorized access even if credentials are compromised. 3) Monitor login attempts and set up alerts for unusual authentication patterns indicative of brute-force attacks. 4) Restrict login access by IP address or network segment where feasible, limiting exposure to the public internet. 5) Encourage strong password policies and regular password changes for administrative users. 6) Engage with Soosyze CMS developers or community to track the release of official patches or updates addressing this vulnerability and plan prompt deployment once available. 7) Consider temporary disabling or restricting the /user/login endpoint if possible during high-risk periods. These measures go beyond generic advice by focusing on compensating controls tailored to the specific vulnerability and CMS environment.
