CVE-2025-60828 identifies a critical deserialization vulnerability in WukongCRM version 9.0 implemented in Java. The vulnerability arises from the use of the fastjson library in the /OaExamine/setOaExamine API endpoint, which improperly handles deserialization of user-supplied data. Fastjson is a popular JSON parsing library, but unsafe deserialization can allow attackers to craft malicious payloads that, when processed, lead to arbitrary code execution or other unauthorized actions on the server. This vulnerability does not currently have a CVSS score or publicly known exploits, but the nature of deserialization flaws typically allows remote attackers to execute code without authentication if they can send crafted requests to the vulnerable endpoint. The lack of patch information suggests that a fix may not yet be publicly available, increasing the urgency for organizations to implement mitigations. The vulnerability affects all deployments of WukongCRM-9.0-JAVA that expose the vulnerable interface and use fastjson without proper security controls. Given the criticality of CRM systems in managing sensitive business data, exploitation could lead to data breaches, system compromise, and disruption of business operations.

For European organizations, exploitation of this vulnerability could result in unauthorized access to sensitive customer and business data managed within WukongCRM, leading to data confidentiality breaches and potential regulatory non-compliance under GDPR. Integrity of CRM data could be compromised, affecting business decisions and customer relations. Availability impacts could arise if attackers execute destructive payloads or disrupt CRM services, causing operational downtime. The vulnerability's remote exploitation potential without authentication increases risk, especially for organizations exposing the vulnerable interface to external networks. Industries relying heavily on CRM systems, such as finance, retail, and professional services, may face heightened risks. Additionally, reputational damage and financial losses from incident response and remediation efforts could be significant. The absence of known exploits currently provides a window for proactive defense, but the threat landscape may evolve rapidly.

Organizations should immediately audit their WukongCRM deployments to identify exposure of the /OaExamine/setOaExamine interface. Until a patch is available, restrict access to this endpoint through network segmentation, firewall rules, or VPN requirements to limit exposure to trusted users only. Implement input validation and sanitization on all data submitted to the vulnerable interface to prevent malicious payloads. Upgrade or patch the fastjson library to a version that includes deserialization security improvements once available. Employ runtime application self-protection (RASP) or web application firewalls (WAF) with custom rules to detect and block suspicious deserialization patterns. Monitor logs for anomalous activity targeting the vulnerable endpoint. Conduct security awareness training for developers and administrators on secure deserialization practices. Finally, establish an incident response plan specific to deserialization attacks to enable rapid containment and recovery.
