CVE-2025-8704: WOES Energy Saving System SQLi Vulnerability

CVE-2025-8704 Overview

CVE-2025-8704 is a SQL injection vulnerability in Wanzhou WOES Intelligent Optimization Energy Saving System 1.0. The flaw resides in the Analysis Conclusion Query Module, specifically in the /WEAS_AlarmResult/GetAlarmResultProcessList endpoint. Attackers manipulate the resultId parameter to inject arbitrary SQL into backend database queries. The vulnerability is classified under [CWE-74] for improper neutralization of special elements in output. Exploitation requires network access and low-level authentication, and a public disclosure of the technique exists.

Critical Impact
Authenticated remote attackers can inject SQL statements via the resultId parameter to read, modify, or exfiltrate data from the application database.

Technical Details for CVE-2025-8704

Vulnerability Analysis

The vulnerability exists in the GetAlarmResultProcessList handler of the Analysis Conclusion Query Module. The application accepts a resultId parameter from the HTTP request and concatenates it directly into a SQL query without parameterization or input sanitization. An attacker with low-privilege authenticated access can send crafted requests to the endpoint and inject arbitrary SQL syntax. This allows the attacker to alter the original query logic, append additional statements, or extract data using UNION-based or boolean-based techniques. Public disclosure of the exploit technique increases the likelihood of opportunistic abuse against exposed instances.

Root Cause

The root cause is improper neutralization of user-supplied input passed to a SQL query [CWE-74]. The resultId argument is not validated, sanitized, or bound through prepared statements. The backend constructs queries using string concatenation, allowing attacker-controlled input to break out of its intended context and modify the SQL command structure.

Attack Vector

The attack is delivered remotely over the network against the vulnerable HTTP endpoint. An authenticated attacker submits a request to /WEAS_AlarmResult/GetAlarmResultProcessList containing a malicious resultId payload. The injected SQL is executed by the database engine in the context of the application's database user. Depending on database privileges, the attacker may enumerate tables, exfiltrate sensitive records, or tamper with stored data. The technique requires no user interaction. See the GitHub Issue Report and VulDB #319133 for additional technical context.

Detection Methods for CVE-2025-8704

Indicators of Compromise

HTTP requests to /WEAS_AlarmResult/GetAlarmResultProcessList containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP in the resultId parameter.
Unexpected database errors or stack traces returned in application logs following requests to the alarm result endpoint.
Anomalous outbound database queries originating from the WOES application service account.

Detection Strategies

Inspect web server and application logs for resultId values containing non-numeric characters, URL-encoded quotes, or SQL keywords.
Deploy web application firewall signatures targeting SQL injection patterns directed at the /WEAS_AlarmResult/ URI path.
Correlate authentication events with subsequent abnormal query patterns at the database tier.

Monitoring Recommendations

Enable database query auditing to capture statements issued by the WOES application service account.
Alert on bursts of failed queries or queries containing unusual UNION, INFORMATION_SCHEMA, or sleep-based constructs.
Monitor response sizes and latency on the GetAlarmResultProcessList endpoint for signs of blind or time-based injection.

How to Mitigate CVE-2025-8704

Immediate Actions Required

Restrict network access to the WOES management interface to trusted administrative networks only.
Audit application and database logs for prior exploitation attempts against the /WEAS_AlarmResult/GetAlarmResultProcessList endpoint.
Rotate database credentials and any application secrets that may have been exposed if compromise is suspected.
Reduce the privileges of the database account used by the WOES application to the minimum required.

Patch Information

No vendor advisory or official patch has been published in the references provided. Operators should contact Wanzhou directly for remediation guidance. Track updates through VulDB CTI ID #319133 for fix availability.

Workarounds

Place the application behind a web application firewall with SQL injection rule sets enabled for the affected URI.
Block or strictly validate requests to /WEAS_AlarmResult/GetAlarmResultProcessList where resultId is not a numeric value.
Remove or disable the Analysis Conclusion Query Module if it is not required for business operations.
Apply input validation at a reverse proxy layer to enforce parameter type and length constraints.

bash

# Example NGINX rule to enforce numeric resultId values
location /WEAS_AlarmResult/GetAlarmResultProcessList {
    if ($arg_resultId !~ "^[0-9]+$") {
        return 400;
    }
    proxy_pass http://woes_backend;
