CVE-2025-14908 is an improper authentication vulnerability identified in JeecgBoot, an open-source rapid development platform widely used for enterprise applications. The flaw resides in the Multi-Tenant Management Module, specifically in the SysTenantController.java file, where manipulation of an argument named ID allows an attacker to bypass authentication mechanisms. This vulnerability affects all versions up to 3.9.0. The attack vector is remote and requires no prior authentication or user interaction, making it relatively easy to exploit. The vulnerability potentially allows unauthorized access to tenant management functions, which could lead to unauthorized data access or modification within a multi-tenant environment. Although the CVSS 4.0 base score is 5.3 (medium), reflecting limited impact on confidentiality, integrity, and availability, the presence of a public exploit increases the urgency for remediation. The patch referenced by commit hashes e1c8f00bf2a2e0edddbaa8119afe1dc92d9dc1d2 and 67795493bdc579e489d3ab12e52a1793c4f8a0ee addresses the authentication bypass by correcting the argument validation logic. No known active exploitation has been reported yet, but the vulnerability’s characteristics make it a credible threat to affected deployments.

For European organizations, the improper authentication vulnerability in JeecgBoot could lead to unauthorized access to multi-tenant management features, potentially exposing sensitive tenant data or allowing unauthorized modifications. This is particularly critical for enterprises relying on JeecgBoot for internal or customer-facing applications that handle regulated or confidential information. The impact on confidentiality arises from possible unauthorized data access; integrity could be compromised if attackers modify tenant configurations or data; availability impact is limited but possible if tenant management functions are disrupted. Given the remote exploitability without authentication, attackers could leverage this vulnerability to escalate privileges or move laterally within affected environments. Organizations in sectors such as finance, healthcare, and government, where multi-tenant applications are common and data protection regulations like GDPR apply, face increased compliance and reputational risks if exploited. The medium severity score suggests moderate risk, but the public availability of an exploit elevates the urgency for mitigation.

1. Immediately apply the official patch provided for JeecgBoot versions up to 3.9.0, specifically the commits e1c8f00bf2a2e0edddbaa8119afe1dc92d9dc1d2 and 67795493bdc579e489d3ab12e52a1793c4f8a0ee, to correct the authentication bypass. 2. Conduct a thorough audit of access logs related to the Multi-Tenant Management Module to detect any suspicious or unauthorized access attempts prior to patching. 3. Restrict network access to the SysTenantController endpoints by implementing firewall rules or network segmentation to limit exposure to trusted internal networks only. 4. Implement additional application-layer access controls and input validation to ensure that ID parameters cannot be manipulated maliciously. 5. Monitor threat intelligence feeds for any emerging exploit activity targeting this vulnerability. 6. Educate development and security teams about secure coding practices to prevent similar authentication issues in custom modules. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block anomalous requests targeting the vulnerable endpoints until patching is complete.
