CVE-2026-14737: Hanwang e-Face Platform SQLi Vulnerability

CVE-2026-14737 Overview

CVE-2026-14737 is a SQL injection vulnerability in Hanwang e-Face General Management Platform version 6.3.5.4. The flaw resides in an unspecified function within the /sysAuthStr/querySysAuthStr.do endpoint. Attackers can manipulate the order parameter to inject arbitrary SQL statements into backend database queries. The vulnerability is remotely exploitable over the network and requires no authentication or user interaction. A public exploit is referenced in third-party vulnerability databases, increasing the likelihood of opportunistic attacks against exposed instances. The weakness is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Unauthenticated remote attackers can inject SQL through the order parameter of /sysAuthStr/querySysAuthStr.do, potentially exposing or modifying data managed by the platform.

Technical Details for CVE-2026-14737

Vulnerability Analysis

The vulnerability affects the /sysAuthStr/querySysAuthStr.do handler in the Hanwang e-Face General Management Platform. The order request parameter is passed into a backend SQL query without proper sanitization or parameterization. Attackers who supply crafted input can alter the query structure, allowing execution of attacker-controlled SQL.

Because the endpoint is exposed over the network and does not require authentication, exploitation only requires reachability to the affected web interface. According to the CVSS 4.0 assessment, the flaw carries limited confidentiality, integrity, and availability impact against the vulnerable database context rather than full system takeover.

EPSS data published on 2026-07-09 lists the exploit probability at 0.259% (17.29 percentile), reflecting a modest but non-negligible likelihood of exploitation given the availability of public technical details in the referenced VulDB entry and Feishu document.

Root Cause

The root cause is improper neutralization of user input in the order parameter before its inclusion in a SQL statement. The application concatenates request data directly into a query string rather than using prepared statements or a strict allowlist for sort-order values. This design flaw enables classic in-band SQL injection through a parameter that typically only carries values such as asc or desc.

Attack Vector

The attack vector is remote and network-based. An attacker sends an HTTP request to /sysAuthStr/querySysAuthStr.do with a malicious payload in the order argument. No credentials are required, and no user interaction is needed to trigger the vulnerable code path. Exploitation techniques include boolean-based, error-based, or UNION-based SQL injection to enumerate schemas, extract data, or manipulate records stored by the management platform.

A publicly referenced proof-of-concept is described in the VulDB submission, and technical details are mirrored in the VulDB vulnerability record. No verified exploit code is reproduced here.

Detection Methods for CVE-2026-14737

Indicators of Compromise

HTTP requests to /sysAuthStr/querySysAuthStr.do containing SQL keywords such as UNION, SELECT, SLEEP, or -- inside the order parameter.
Unusual database query patterns or errors originating from the e-Face application service account.
Unexpected outbound connections from the platform host following requests to the vulnerable endpoint.

Detection Strategies

Deploy Web Application Firewall (WAF) rules that inspect the order parameter for SQL metacharacters and known injection payloads.
Enable database query logging and alert on anomalous statements originating from the e-Face application, especially queries containing sort clauses with concatenated user input.
Correlate web access logs with database audit logs to identify request-to-query pairs that indicate injection attempts.

Monitoring Recommendations

Monitor authentication and privilege changes within the platform's underlying database for signs of tampering.
Track HTTP 500 responses and database exceptions returned from /sysAuthStr/querySysAuthStr.do, which often accompany early injection probing.
Alert on repeated requests to the vulnerable path from a single source, particularly with parameter values that differ from expected asc/desc tokens.

How to Mitigate CVE-2026-14737

Immediate Actions Required

Restrict network access to the Hanwang e-Face General Management Platform to trusted management networks only.
Deploy WAF signatures blocking SQL injection payloads targeting the order parameter of /sysAuthStr/querySysAuthStr.do.
Review web and database logs for evidence of prior exploitation attempts against the affected endpoint.
Contact Hanwang support to confirm patch availability for version 6.3.5.4.

Patch Information

No vendor advisory or patch reference is listed in the NVD entry at the time of publication. Administrators should consult the vendor directly and monitor the VulDB entry for updates on fixed builds.

Workarounds

Place the platform behind a reverse proxy that enforces strict input validation on the order parameter, allowing only asc and desc values.
Apply network segmentation and IP allowlisting so only administrative hosts can reach the management interface.
Disable or block external access to /sysAuthStr/querySysAuthStr.do if the endpoint is not required for daily operations.
Enable database-layer least-privilege controls to limit the impact of successful injection against the application service account.

bash

# Example nginx snippet to restrict access and validate the 'order' parameter
location /sysAuthStr/querySysAuthStr.do {
    allow 10.0.0.0/24;   # management subnet
    deny all;

    if ($arg_order !~* "^(asc|desc)$") {
        return 400;
    }

    proxy_pass http://eface_backend;
