CVE-2025-10978 is a medium-severity security vulnerability affecting JeecgBoot versions up to 3.8.2. The flaw resides in an unspecified function within the /sys/user/exportXls endpoint of the Filter Handler component. This vulnerability results in improper authorization, allowing an attacker to remotely exploit the system without requiring user interaction or elevated privileges beyond low-level privileges. The vulnerability permits unauthorized access or actions that should be restricted, potentially exposing sensitive user data or enabling unauthorized data export operations. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality (VC:L), with no impact on integrity or availability. Although the vendor has been notified, no patch or response has been issued, and a public exploit has been released, increasing the risk of exploitation. The vulnerability's root cause is improper authorization checks, which could allow attackers to bypass access controls on the exportXls functionality, potentially leading to data leakage or unauthorized data extraction from the affected system.

For European organizations using JeecgBoot, particularly those relying on the affected versions (3.8.0 to 3.8.2), this vulnerability poses a risk of unauthorized data exposure or leakage through the exportXls endpoint. Given that JeecgBoot is a rapid development platform often used in enterprise applications, exploitation could lead to unauthorized export of user or business data, violating data protection regulations such as GDPR. This could result in legal penalties, reputational damage, and operational disruptions. The medium CVSS score reflects moderate risk; however, the public availability of an exploit increases the likelihood of attacks. Organizations in sectors handling sensitive or regulated data (e.g., finance, healthcare, government) are particularly at risk. The lack of vendor response and patch availability means organizations must proactively implement mitigations to reduce exposure. The vulnerability does not directly affect system integrity or availability but compromises confidentiality to a limited extent, which can still have significant compliance and trust implications.

Since no official patch is available, European organizations should immediately audit their JeecgBoot deployments to identify affected versions. Mitigation steps include: 1) Restrict network access to the /sys/user/exportXls endpoint using firewall rules or web application firewalls (WAF) to limit exposure to trusted IPs only. 2) Implement additional access control checks at the application or proxy level to enforce proper authorization before allowing data export operations. 3) Monitor logs for unusual or unauthorized access attempts to the exportXls endpoint to detect exploitation attempts early. 4) Consider temporarily disabling or removing the exportXls functionality if feasible until a patch is released. 5) Engage in vendor communication channels to demand timely patching and updates. 6) Educate development and security teams about this vulnerability to ensure awareness and readiness to respond to incidents. 7) Review and enhance overall authorization mechanisms in the application to prevent similar issues.
