Technical Analysis

CVE-2025-4533 is a medium-severity vulnerability identified in JeecgBoot versions up to 3.8.0, specifically affecting the unzipFile function within the Document Library Upload component located at /jeecg-boot/airag/knowledge/doc/import/zip. The vulnerability arises from improper handling of the File argument, which can be manipulated by an attacker to cause excessive resource consumption on the affected system. This type of vulnerability is typically classified as a resource exhaustion or denial-of-service (DoS) risk, where an attacker remotely triggers the unzipFile function with crafted input to overload system resources such as CPU, memory, or disk I/O. The CVSS 4.0 vector indicates the attack can be performed remotely (AV:N) without user interaction (UI:N) but requires high privileges (PR:H), suggesting that the attacker must have authenticated access with elevated permissions to exploit the flaw. The vulnerability does not impact confidentiality, integrity, or availability directly but leads to resource consumption that can degrade system performance or cause service disruptions. Although no public exploits are currently known in the wild, the vulnerability has been disclosed publicly, increasing the risk of future exploitation. The absence of patches at the time of reporting means affected organizations must rely on mitigation strategies until official fixes are released. JeecgBoot is an open-source rapid development platform widely used for enterprise applications, meaning this vulnerability could affect business-critical systems that utilize this framework for document management and upload functionalities.

Potential Impact

For European organizations using JeecgBoot, this vulnerability poses a risk of service degradation or denial-of-service conditions in applications relying on the Document Library Upload feature. Resource exhaustion attacks can lead to application unavailability, impacting business operations, especially in sectors where document processing is critical such as finance, healthcare, and government services. Since exploitation requires high privileges, the threat is more relevant to insider threats or attackers who have already compromised user credentials with elevated access. The impact on confidentiality and integrity is minimal; however, availability disruptions could affect compliance with service-level agreements and regulatory requirements like GDPR if services become unavailable or unstable. Organizations with large-scale deployments or those exposed to external networks where authenticated users can upload files are at higher risk. The public disclosure of the vulnerability increases the urgency for European entities to assess their exposure and implement mitigations promptly to prevent potential exploitation.

Mitigation Recommendations

1. Restrict access to the unzipFile functionality to only trusted and necessary users with elevated privileges, minimizing the attack surface. 2. Implement strict input validation and file size limits on uploaded ZIP files to prevent maliciously crafted files from triggering resource exhaustion. 3. Monitor resource usage patterns on servers running JeecgBoot to detect abnormal spikes indicative of exploitation attempts. 4. Employ application-layer firewalls or runtime application self-protection (RASP) solutions to detect and block suspicious file upload activities. 5. Isolate the document upload service in a sandboxed or containerized environment to limit the impact of resource exhaustion on other system components. 6. Regularly review and update user access controls to ensure only authorized personnel have high privilege levels required to exploit this vulnerability. 7. Stay alert for official patches or updates from JeecgBoot maintainers and apply them promptly once available. 8. Conduct internal security audits and penetration testing focusing on file upload functionalities to identify and remediate similar weaknesses.
