CVE-2025-7824 is a security vulnerability identified in Jinher OA version 1.1, specifically related to the processing of the XmlHttp.aspx file. The vulnerability is classified as an XML External Entity (XXE) reference issue. XXE vulnerabilities occur when an XML parser improperly processes external entity references within XML input, allowing an attacker to interfere with the processing of XML data. In this case, the vulnerability allows remote attackers to manipulate XML input to trigger external entity references. This can lead to several security risks, including disclosure of confidential files on the server, server-side request forgery (SSRF), denial of service (DoS) through resource exhaustion, and potentially remote code execution depending on the environment and further exploitation. The vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 score is 6.9 (medium severity), reflecting the ease of exploitation (network accessible, no privileges or user interaction required) but limited impact on confidentiality, integrity, and availability (each rated low). No patches or mitigations are currently linked, and no known exploits are reported in the wild yet, though public disclosure of the exploit details increases the risk of exploitation attempts. The vulnerability affects only version 1.1 of Jinher OA, an office automation software product, which is used for managing organizational workflows and documents.

For European organizations using Jinher OA 1.1, this vulnerability poses a moderate risk. Exploitation could lead to unauthorized disclosure of sensitive internal documents or data, which may include personal data protected under GDPR, potentially resulting in regulatory penalties and reputational damage. Additionally, attackers could leverage the vulnerability to perform SSRF attacks, potentially pivoting into internal networks or accessing restricted resources. Denial of service attacks could disrupt business operations relying on Jinher OA. Given the medium severity and the lack of authentication requirements, attackers could automate exploitation attempts, increasing risk. Organizations in sectors with high regulatory scrutiny or handling sensitive information, such as finance, healthcare, and government, are particularly at risk. The absence of a patch necessitates immediate mitigation to prevent exploitation. The impact is amplified if Jinher OA is integrated with other critical systems or used as a gateway to internal networks.

European organizations should take the following specific steps: 1) Immediately audit their environment to identify any deployments of Jinher OA version 1.1. 2) If possible, isolate affected systems from external network access or restrict access to trusted IPs to reduce exposure. 3) Implement Web Application Firewall (WAF) rules to detect and block XML payloads containing external entity references or suspicious XML structures targeting XmlHttp.aspx. 4) Disable XML external entity processing in the XML parser configuration if configurable within Jinher OA or underlying frameworks. 5) Monitor logs for unusual XML requests or errors related to XmlHttp.aspx to detect exploitation attempts. 6) Engage with Jinher vendor support channels to obtain patches or official guidance as soon as available. 7) Consider upgrading to a newer, unaffected version once released. 8) Conduct internal awareness training for IT and security teams about this vulnerability and the risks of XXE attacks. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable component and practical network-level controls.
