CVE-2025-10771 is a medium severity remote deserialization vulnerability affecting the jeecgboot JimuReport product, specifically versions 2.1.0 through 2.1.2. The vulnerability resides in an unspecified function within the /drag/onlDragDataSource/testConnection endpoint of the DB2 JDBC Handler component. The issue arises from the manipulation of the argument clientRerouteServerListJNDIName, which can be exploited to trigger unsafe deserialization of untrusted data. This flaw allows an unauthenticated remote attacker to send crafted input to the vulnerable endpoint, resulting in the deserialization of malicious objects. Such deserialization vulnerabilities can lead to arbitrary code execution, data tampering, or denial of service, depending on the payload and application context. The vulnerability does not require user interaction and has a low complexity of attack, with no privileges required. The CVSS 4.0 base score is 5.3, reflecting a medium severity level due to limited impact on confidentiality, integrity, and availability (all rated low), but with a fully remote attack vector and no user interaction needed. Although no public exploits are currently known in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The lack of patches or mitigation links indicates that users of affected versions should consider immediate risk mitigation steps. The vulnerability specifically targets the DB2 JDBC Handler component, suggesting that environments using IBM DB2 databases with JimuReport are at risk. Given the remote nature and ease of exploitation, this vulnerability poses a tangible threat to organizations using affected versions of JimuReport in their reporting or data integration workflows.

For European organizations, the impact of CVE-2025-10771 can be significant depending on their deployment of jeecgboot JimuReport, particularly if integrated with IBM DB2 databases. Successful exploitation could lead to unauthorized remote code execution or data manipulation, potentially compromising sensitive business intelligence data or disrupting reporting services. This could affect confidentiality by exposing sensitive report data, integrity by altering report contents or database queries, and availability by causing application crashes or denial of service. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face regulatory and reputational damage if exploited. The remote and unauthenticated nature of the vulnerability increases the attack surface, especially for externally accessible JimuReport instances. Given the medium severity score and no known exploits in the wild yet, the immediate risk is moderate but could escalate rapidly following exploit development. The lack of patches means organizations must rely on compensating controls to reduce exposure. Overall, the vulnerability could disrupt critical reporting infrastructure and lead to data breaches or operational downtime if not addressed promptly.

1. Immediate mitigation should include restricting network access to the vulnerable /drag/onlDragDataSource/testConnection endpoint, ideally limiting it to trusted internal networks or VPNs. 2. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious deserialization payloads or anomalous requests targeting the clientRerouteServerListJNDIName parameter. 3. Monitor logs for unusual activity or malformed requests to the affected endpoint to enable early detection of exploitation attempts. 4. If possible, disable or isolate the DB2 JDBC Handler component within JimuReport until a vendor patch is available. 5. Engage with the jeecgboot vendor or community to obtain updates or patches as soon as they are released. 6. Conduct code reviews or penetration testing focused on deserialization and input validation in JimuReport deployments. 7. Apply network segmentation to limit the exposure of JimuReport servers and associated databases. 8. Educate security teams about this vulnerability to ensure rapid incident response if exploitation is detected. These targeted mitigations go beyond generic advice by focusing on access controls, monitoring, and component isolation specific to the vulnerability context.
