CVE-2025-11321 is an authorization bypass vulnerability identified in the zhuimengshaonian wisdom-education software, specifically affecting versions 1.0.0 through 1.0.4. The vulnerability resides in an unspecified function within the WrongBookController.java source file, part of the API controller handling student-related operations. By manipulating the subjectId parameter, an attacker can bypass authorization mechanisms, gaining unauthorized access to resources or actions that should be restricted. The attack vector is remote network access, requiring no authentication or user interaction, which increases the attack surface. The CVSS 4.0 vector indicates low complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impact on confidentiality (VC:L), with no impact on integrity or availability. Although no exploits have been observed in the wild, public exploit code is available, suggesting that attackers could leverage this vulnerability to access sensitive educational data or functionality. The lack of patches or official remediation links in the provided data suggests that organizations must implement compensating controls or monitor for exploitation attempts until a patch is available. This vulnerability highlights the importance of strict authorization checks on input parameters in web applications, especially those handling sensitive educational data.

For European organizations, particularly educational institutions or edtech providers using the zhuimengshaonian wisdom-education platform, this vulnerability poses a risk of unauthorized access to student data or restricted application functions. Such unauthorized access could lead to data leakage, privacy violations under GDPR, and potential reputational damage. Since the vulnerability allows remote exploitation without authentication, attackers could operate from outside the network perimeter, increasing the risk of widespread exploitation. The partial confidentiality impact means sensitive information could be exposed, which is critical in education environments handling minors' data. Additionally, unauthorized access could be leveraged to manipulate educational records or gain footholds for further attacks. The medium severity score reflects moderate risk but should not be underestimated given the sensitivity of educational data and regulatory requirements in Europe.

European organizations should immediately audit their deployments of zhuimengshaonian wisdom-education to identify affected versions (1.0.0 to 1.0.4). In the absence of an official patch, implement strict server-side validation and authorization checks on the subjectId parameter within the WrongBookController API endpoint to ensure users can only access resources they are permitted to. Employ web application firewalls (WAFs) to detect and block suspicious requests manipulating subjectId or exhibiting anomalous patterns. Conduct thorough logging and monitoring of API access to detect potential exploitation attempts. Limit network exposure of the affected application by restricting access to trusted networks or VPNs. Engage with the vendor for patch timelines and apply updates promptly once available. Additionally, perform regular security assessments and penetration tests focusing on authorization controls to prevent similar vulnerabilities.
