CVE-2025-7798: Beijing Shenzhou Shihan SQL Injection Flaw

CVE-2025-7798 Overview

CVE-2025-7798 is a SQL injection vulnerability in Beijing Shenzhou Shihan Technology Multimedia Integrated Business Display System versions up to 8.2. The flaw resides in the /admin/system/structure/getdirectorydata/web/baseinfo/companyManage endpoint. Attackers can manipulate the Struccture_ID parameter to inject arbitrary SQL statements. The vulnerability is remotely exploitable and requires low-privileged authentication. Public disclosure of the exploit technique has occurred, increasing the risk of opportunistic attacks against exposed instances.

Critical Impact

Authenticated remote attackers can inject SQL statements via the Struccture_ID parameter, potentially exposing or modifying backend database contents.

Affected Products

• Beijing Shenzhou Shihan Technology Multimedia Integrated Business Display System versions up to and including 8.2
• Deployments exposing the /admin/system/structure/getdirectorydata/web/baseinfo/companyManage endpoint
• Web administration consoles reachable over the network

Technical Details for CVE-2025-7798

Vulnerability Analysis

The vulnerability is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The affected component processes the Struccture_ID request parameter without applying parameterized queries or input sanitization. An authenticated attacker submits a crafted request that extends the intended SQL statement with attacker-controlled clauses. The backend database executes the combined query, returning or modifying data outside the intended authorization scope.

According to the EPSS (Exploit Prediction Scoring System), the probability of exploitation activity in the next 30 days is 0.246%. The attack can be initiated remotely and does not require user interaction, lowering the operational barrier for exploitation.

Root Cause

The root cause is the direct concatenation of the Struccture_ID HTTP parameter into a SQL query executed by the companyManage directory data handler. The application does not validate the parameter type, enforce an allowlist, or bind the value as a prepared-statement parameter. Any input containing SQL control characters or operators is interpreted by the database engine.

Attack Vector

Exploitation occurs over the network against the administrative interface. The attacker must hold a low-privileged account to reach the vulnerable endpoint. Once authenticated, the attacker submits a modified Struccture_ID value containing SQL metacharacters, union statements, or boolean conditions to enumerate schema data, extract records, or alter stored values.

Detection Methods for CVE-2025-7798

Indicators of Compromise

• HTTP requests to /admin/system/structure/getdirectorydata/web/baseinfo/companyManage containing SQL metacharacters such as single quotes, UNION, SELECT, --, or /* within the Struccture_ID parameter
• Unexpected database error responses or anomalous response sizes from the companyManage endpoint
• Authenticated sessions issuing high volumes of requests to the directory data handler within short time windows

Detection Strategies

• Deploy web application firewall rules that inspect the Struccture_ID parameter for SQL injection payload patterns
• Enable database query logging and alert on queries referencing the companyManage handler that contain tautologies or UNION-based constructs
• Correlate web server access logs with database audit logs to identify parameter manipulation followed by schema enumeration

Monitoring Recommendations

• Monitor administrative endpoints for authenticated accounts that deviate from baseline request patterns
• Track outbound data volume from the database server to detect bulk extraction attempts
• Review authentication logs for credential stuffing or brute-force activity targeting low-privileged administrative accounts

How to Mitigate CVE-2025-7798

Immediate Actions Required

• Restrict network access to the /admin/system/structure/ path to trusted management networks only
• Rotate credentials for any low-privileged accounts that could reach the vulnerable endpoint
• Audit database contents and recent query logs for signs of unauthorized read or write activity

Patch Information

No vendor patch has been published in the referenced advisories. Monitor the GitHub CVE Documentation and VulDB entry #316863 for updates from Beijing Shenzhou Shihan Technology.

Workarounds

• Place the administrative interface behind a VPN or IP allowlist to eliminate internet exposure
• Deploy WAF signatures that block SQL metacharacters within the Struccture_ID parameter
• Enforce least-privilege database accounts so the application cannot modify schema or access unrelated tables
• Disable the companyManage directory data endpoint if it is not operationally required

# Example nginx location block restricting administrative access
location /admin/system/structure/ {
    allow 10.0.0.0/8;
    deny all;
    proxy_pass http://backend;
}
