CVE-2024-29400 is an information disclosure vulnerability identified in RuoYi version 4.5.1, a popular Java-based rapid development framework widely used for enterprise applications. The vulnerability arises from improper handling of the 'status' parameter, which attackers can manipulate to retrieve sensitive information without authentication. The flaw is categorized under CWE-200, indicating that sensitive data is exposed to unauthorized parties. The CVSS v3.1 base score is 7.5, reflecting a high severity level due to the vulnerability's network accessibility (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality (C:H), with no effect on integrity or availability. Although the affected versions are not explicitly detailed beyond v4.5.1, the absence of patch links suggests that a fix may not yet be publicly available. The vulnerability allows remote attackers to exploit the 'status' parameter to extract sensitive data, potentially including configuration details, user information, or internal system states, which could facilitate further attacks or data breaches. No known exploits have been reported in the wild as of the publication date, but the ease of exploitation and the nature of the exposed data make it a critical concern for organizations using RuoYi.

The primary impact of CVE-2024-29400 is the unauthorized disclosure of sensitive information, which can compromise confidentiality and potentially aid attackers in planning subsequent attacks such as privilege escalation, lateral movement, or targeted data theft. Organizations relying on RuoYi v4.5.1 for their enterprise applications risk exposure of internal system details or user data, which could lead to reputational damage, regulatory penalties, and loss of customer trust. Since the vulnerability requires no authentication and can be exploited remotely, it significantly lowers the barrier for attackers, increasing the likelihood of exploitation. Although integrity and availability are not directly affected, the information leakage alone can have cascading effects on overall security posture. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit code could be developed rapidly given the vulnerability's simplicity.

Organizations should immediately assess their use of RuoYi, particularly version 4.5.1, and monitor official channels for patches or updates addressing CVE-2024-29400. In the absence of an official patch, implement strict network segmentation and access controls to limit exposure of the vulnerable application endpoints, especially restricting access to trusted internal networks or VPNs. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests manipulating the 'status' parameter. Conduct thorough code reviews and security testing to identify and remediate similar information disclosure issues in custom implementations or forks of RuoYi. Additionally, implement robust logging and monitoring to detect anomalous access patterns that may indicate exploitation attempts. Educate development teams on secure parameter handling and input validation to prevent future vulnerabilities of this nature.
