SQL Injection in Jinher OA File Parameter Handling

A flaw has been found in Jinher OA 1.0. The affected element is an unknown function of the file /C6/JHSoft.Web.PlanSummarize/PlanGiveOut.aspx. This manipulation of the argument httpOID causes sql injection. Remote exploitation of the attack is possible. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Casky was already ahead

This CVE exploits attack patterns that Casky's 322matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

Jinher OA 1.0 contains a critical SQL injection vulnerability in the PlanGiveOut.aspx file where the httpOID parameter is improperly sanitized before being used in database queries. This vulnerability allows remote attackers to execute arbitrary SQL commands without authentication, potentially leading to unauthorized data access, modification, or deletion. Organizations deploying Jinher OA—commonly used for office automation and workflow management in enterprise environments—face immediate risk, particularly since the vendor has not responded to disclosure efforts and exploit code is publicly available. The vulnerability's CVSS score of 7.3 reflects the high severity of unauthenticated remote database manipulation.

Casky's 322 matching security skills leverage Claude's extended reasoning to detect the attack patterns underlying this CVE across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance for discovery of injection points). Practitioners using Casky would receive findings highlighting CWE-74 (Improper Neutralization of Special Elements in Output) and CWE-89 (SQL Injection) signatures—detection of suspicious httpOID parameter values, unusual SQL syntax patterns in network traffic, and database query anomalies indicative of injection attempts. The platform's skill mapping would surface indicators such as malformed parameter encoding, multiple failed query attempts, and database schema enumeration queries that precede successful exploitation, enabling security teams to identify and block attack chains before data exfiltration occurs.
