CVE-2025-61188 is a path traversal vulnerability affecting Jeecgboot versions 3.8.2 and earlier. Jeecgboot is a rapid development platform often used for enterprise applications. The vulnerability arises because the application improperly restricts file upload destinations, allowing attackers to bypass the intended upload directory (/opt/upFiles) and instead place files into the system directory /opt. This is possible due to insufficient validation of file paths during the upload process, enabling path traversal attacks. By exploiting this flaw, an attacker can upload files with system-whitelisted extensions directly into sensitive system directories. This could lead to unauthorized file placement, potentially allowing execution of malicious code, modification of system files, or persistence mechanisms. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk because it undermines the integrity and security boundaries of the system's file structure. The lack of a CVSS score indicates that the vulnerability is newly published and has not yet been fully assessed or exploited. However, the nature of the vulnerability suggests it could be leveraged for privilege escalation or remote code execution if combined with other weaknesses or misconfigurations.

For European organizations using Jeecgboot, this vulnerability could have severe consequences. Enterprises relying on Jeecgboot for critical business applications may face risks including unauthorized code execution, data tampering, or system compromise. The ability to upload files outside the designated directory could allow attackers to implant backdoors or malware, leading to potential data breaches or service disruptions. This is particularly concerning for sectors with strict regulatory requirements such as finance, healthcare, and government, where data integrity and confidentiality are paramount. Additionally, the compromise of system directories could facilitate lateral movement within corporate networks, increasing the scope of an attack. Given the widespread adoption of Java-based rapid development platforms in Europe, the vulnerability could affect a broad range of organizations, especially those that have not applied recent security updates or lack robust file upload validation controls.

To mitigate this vulnerability, organizations should immediately audit their use of Jeecgboot and identify affected versions (3.8.2 and earlier). Until an official patch is released, administrators should implement strict input validation and sanitization on file upload paths to prevent path traversal sequences (e.g., ../). Restrict file upload permissions at the operating system level to prevent writes outside the intended directories, using mechanisms such as chroot jails or containerization. Employ application-level whitelisting of allowed file types and enforce strict directory permissions on /opt and /opt/upFiles to limit unauthorized file placement. Monitoring and alerting for unusual file system changes in critical directories can help detect exploitation attempts early. Additionally, organizations should prepare to deploy patches promptly once available and conduct penetration testing focused on file upload functionalities to identify residual risks. Network segmentation and least privilege principles should be enforced to limit the impact of any successful exploitation.
