Horizon Alert
Summary of the vulnerability and why it matters
A critical vulnerability has been identified in jishenghua JSH_ERP software, specifically related to how it handles data processing. This issue could allow unauthorized access and control over systems using the affected software due to insecure deserialization of data. The primary concern is confirming if our environment utilizes this specific software and version, and if so, assessing the potential exposure.
- Software flaws allow remote system compromise.
- Critical systems could be at risk if exposed.
- Confirm relevance and potential exposure immediately.
Attack Path
How an attacker could exploit the issue
An attacker can reach the vulnerable component by sending a specially crafted request to a web API endpoint. This endpoint, designed to retrieve material information, is exposed externally and requires no authentication or user interaction to trigger. If successful, the vulnerability allows an attacker to execute arbitrary code on the server.
- Accessible via network.
- Triggered by API request parameter.
- Allows remote code execution.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated attacker to execute arbitrary code on the server when the affected endpoint processes a specially crafted request. This could impact the integrity and availability of the JSH_ERP application and its underlying system, when accessible over a network.
- Server-side code execution.
- Network requests trigger deserialization.
- Compromise of application and system.
Operational Fix
Recommended remediation, mitigation, and detection steps
The jishenghua JSH_ERP application, specifically version 2.3.1, contains a critical Fastjson deserialization vulnerability that allows for Remote Code Execution (RCE). This vulnerability is accessible via the `/material/getMaterialEnableSerialNumberList` endpoint and can be exploited through JDBC payloads. Identifying where this application is deployed, confirming its reachability and business criticality, and assigning ownership are the crucial first steps. Subsequently, a risk-based remediation plan should be developed, which may involve coordinating with the vendor or implementing temporary risk reduction measures if immediate patching is not feasible.
- Application owners should lead remediation efforts.
- Verify JSH_ERP deployment reachability and criticality.
- Plan and coordinate vendor-assisted patching.
