CVE-2025-7823: Jinher OA 1.2 Vulnerable to XXE Injection
Jinher OA 1.2 is susceptible to an XML External Entity (XXE) injection vulnerability, potentially allowing attackers to read sensitive files on the server. This post details the vulnerability, its impact, and how to mitigate the risk.
Vulnerability Details
- CVE ID: CVE-2025-7823
- Description: An XXE vulnerability exists in Jinher OA 1.2 within the ProjectScheduleDelete.aspx file. This allows a remote attacker to potentially inject malicious XML code, leading to the disclosure of sensitive information.
- CVSS Score: 7.3 (HIGH)
- CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
- CVSS v3.1 Explanation: The vulnerability is remotely exploitable with low complexity and requires no privileges or user interaction. The impact is limited to low confidentiality, integrity, and availability. This means an attacker could potentially read some sensitive data, modify some application data, and cause limited disruption of service.
- Exploit Requirements: The attacker needs network access to the affected Jinher OA 1.2 instance. No authentication is required.
- Affected Vendor: Jinher
- Affected Product: OA
- Affected Version: 1.2
- CWE: CWE-611 (Improper Restriction of XML External Entity Reference) & CWE-610 (Reliance on untrusted inputs in a security decision)
- CWE Explanation: CWE-611 refers to vulnerabilities that arise when an application processes XML input containing external entity references without proper sanitization. CWE-610 occurs when an application relies on untrusted input to make security decisions, leading to potential vulnerabilities such as XXE.

Exploitability & Real-World Risk
The XXE vulnerability in Jinher OA 1.2 poses a significant risk. An attacker can potentially exploit this flaw to:
- Read local files on the server, potentially including configuration files, database credentials, and source code.
- Cause denial of service by exploiting the XML parser.
- Potentially achieve remote code execution in certain configurations.
Given the ease of exploitation and the potential for sensitive data exposure, organizations using Jinher OA 1.2 should take immediate action to mitigate this vulnerability.
Recommendations
- Apply Patches: Check for any available patches or updates from Jinher and apply them immediately.
- Disable External Entities: Configure the XML parser to disable external entities processing.
- Input Validation: Implement strict input validation to prevent the injection of malicious XML code.
- Web Application Firewall (WAF): Deploy a WAF to detect and block XXE attacks.
- Monitor for Suspicious Activity: Regularly monitor your systems for any unusual activity that may indicate an attempted exploitation.
Technical Insight
The vulnerability lies in the `ProjectScheduleDelete.aspx` file, where the application processes XML input without proper sanitization. By injecting a malicious XML payload containing an external entity reference, an attacker can trick the XML parser into accessing arbitrary files on the server. The parser, attempting to resolve the external entity, fetches the content of the specified file and returns it to the attacker.
