CVE-2025-10492 is a critical deserialization vulnerability classified under CWE-502 affecting the Jaspersoft JasperReports Library Community Edition, a widely used Java reporting tool. The flaw stems from the library's improper handling of externally supplied serialized data, which can be crafted by an attacker to execute arbitrary code remotely on vulnerable systems. This vulnerability does not require user interaction or prior authentication, significantly increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) indicates network attack vector, low complexity, no authentication or user interaction needed, and high impact on confidentiality, integrity, and availability. Although no public exploits are currently known, the nature of Java deserialization vulnerabilities historically leads to rapid exploit development. JasperReports Library is embedded in many enterprise applications for generating reports, making this vulnerability a critical risk for organizations relying on Java-based reporting infrastructure. The lack of available patches at the time of disclosure necessitates immediate risk mitigation through network segmentation, input validation, and monitoring. The vulnerability's exploitation could lead to full system compromise, data breaches, and disruption of business-critical reporting services.

For European organizations, exploitation of CVE-2025-10492 could result in severe consequences including unauthorized remote code execution, data theft, disruption of reporting services, and potential lateral movement within enterprise networks. Given the widespread use of JasperReports in financial, governmental, healthcare, and manufacturing sectors across Europe, the vulnerability poses a significant threat to data confidentiality and operational integrity. Attackers could leverage this flaw to deploy ransomware, exfiltrate sensitive data, or establish persistent footholds. The high severity and ease of exploitation without user interaction increase the likelihood of targeted attacks, especially against organizations with exposed JasperReports instances. Disruption of reporting capabilities could also impact compliance reporting and decision-making processes, amplifying operational risks. The absence of known exploits currently provides a window for proactive defense, but the threat landscape may rapidly evolve once exploit code becomes available.

1. Monitor Jaspersoft's official channels for patches or updates addressing CVE-2025-10492 and apply them promptly once released. 2. Restrict network access to JasperReports Library services using firewalls and network segmentation to limit exposure to untrusted sources. 3. Implement strict input validation and deserialization controls, such as using allowlists for acceptable serialized classes or employing safer serialization frameworks. 4. Deploy runtime application self-protection (RASP) or web application firewalls (WAFs) configured to detect and block suspicious deserialization payloads. 5. Conduct thorough audits of all applications embedding JasperReports to identify vulnerable versions and assess exposure. 6. Enhance logging and monitoring to detect anomalous deserialization attempts or unusual process behavior indicative of exploitation. 7. Educate development and security teams about secure deserialization practices and the risks associated with untrusted data. 8. Consider isolating JasperReports services in dedicated environments with minimal privileges to contain potential compromises.
