CVE-2024-7327 Overview
CVE-2024-7327 is a SQL injection vulnerability in Xinhu RockOA 2.6.2, an office automation platform. The flaw resides in the dataAction function within /webmain/task/openapi/openmodhetongAction.php. Attackers can manipulate the nickName parameter to inject arbitrary SQL statements against the backend database. The attack is remotely exploitable and requires low-level privileges. Public disclosure includes proof-of-concept details published through VulDB as identifier VDB-273250. The vendor was contacted before public disclosure but did not respond. This vulnerability is classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).
Critical Impact
Authenticated remote attackers can inject SQL commands through the nickName parameter, potentially exposing database contents, credentials, and business records stored in the RockOA application.

Technical Details for CVE-2024-7327
Vulnerability Analysis
The vulnerability exists in the dataAction function of openmodhetongAction.php, a component of the RockOA OpenAPI module. The application accepts user-supplied input via the nickName parameter without proper sanitization or parameterization. This input is concatenated directly into a SQL query executed against the backend database. Successful exploitation allows attackers to alter query logic, extract data from arbitrary tables, and potentially escalate to further compromise. The exploit has been publicly disclosed and may be reused by opportunistic attackers targeting exposed RockOA deployments.
Root Cause
The root cause is improper input neutralization ([CWE-89]). The dataAction handler concatenates the nickName argument into a SQL statement instead of using prepared statements or parameterized queries. No allowlist validation or encoding is applied before the value reaches the database driver.
Attack Vector
Attackers deliver a crafted HTTP request to the /webmain/task/openapi/openmodhetongAction.php endpoint. The nickName parameter carries the SQL payload. Because the endpoint is exposed over the network and requires only low-level authentication, remote attackers with any valid session context can trigger the injection. See the VulDB entry #273250 and the Shikangsi Wiki writeup for public exploitation details.

Detection Methods for CVE-2024-7327
Indicators of Compromise
- HTTP requests to /webmain/task/openapi/openmodhetongAction.php containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP, or comment sequences in the nickName parameter.
- Unusual database error messages returned by the RockOA application referencing SQL syntax failures.
- Web server access logs showing repeated requests to the openmodhetongAction endpoint from a single source with varying nickName values.
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect the nickName parameter on the openmodhetongAction.php endpoint for SQL injection patterns.
- Enable database query logging and alert on queries containing tautologies, UNION SELECT operations, or references to information_schema originating from the RockOA service account.
- Correlate authentication events with subsequent anomalous database activity to identify low-privilege accounts probing the endpoint.
Monitoring Recommendations
- Monitor outbound data volume from the RockOA database server for signs of bulk extraction.
- Baseline normal request patterns for /webmain/task/openapi/ endpoints and alert on deviations in parameter length or content.
- Retain and review application error logs for stack traces referencing SQL execution paths from the dataAction function.
How to Mitigate CVE-2024-7327
Immediate Actions Required
- Restrict network access to the RockOA application to trusted internal networks or VPN users until a fix is available.
- Audit account activity on the RockOA platform and revoke sessions for accounts that show suspicious query patterns.
- Deploy WAF signatures blocking SQL injection payloads targeting the nickName parameter on openmodhetongAction.php.
Patch Information
No vendor patch is available. The vendor was contacted before public disclosure and did not respond, according to the VulDB entry. Organizations running Xinhu RockOA 2.6.2 should track vendor communications and apply any subsequent updates immediately upon release.
Workarounds
- Place the RockOA application behind a reverse proxy that filters or rejects requests containing SQL metacharacters in the nickName parameter.
- Remove or restrict the /webmain/task/openapi/openmodhetongAction.php endpoint at the web server level if it is not required for business operations.
- Apply the principle of least privilege to the database account used by RockOA, limiting it to only the tables and operations required by the application.
