CVE-2025-10712: 07FLYCMS SQL Injection Vulnerability

CVE-2025-10712 Overview

CVE-2025-10712 is a SQL injection vulnerability affecting 07FLYCMS, 07FLY-CMS, and 07FlyCRM versions up to 20250831. The flaw resides in the /index.php/Login/login endpoint, where the Username parameter is passed to a database query without proper sanitization. Remote attackers can exploit this issue over the network without authentication or user interaction. The exploit details have been made public, increasing the likelihood of opportunistic attacks. The vendor was contacted prior to disclosure but did not respond. This vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Unauthenticated remote attackers can inject arbitrary SQL through the login form, potentially exposing or modifying backend database contents.

Affected Products

07FLYCMS up to version 20250831
07FLY-CMS up to version 20250831
07FlyCRM up to version 20250831

Technical Details for CVE-2025-10712

Vulnerability Analysis

The vulnerability resides in the login handler reachable at /index.php/Login/login. The application accepts the Username parameter from client-supplied input and embeds it into a SQL query without parameterization or escaping. Attackers can append SQL syntax to the Username field to alter query semantics. Because the endpoint is exposed before authentication, exploitation requires no credentials or prior access. According to the EPSS data, this issue carries a low probability of near-term exploitation, but public exploit availability raises the practical risk for exposed instances.

Root Cause

The root cause is improper neutralization of special characters in input destined for a SQL interpreter, consistent with [CWE-74]. The login controller concatenates user-supplied data directly into a query string instead of using prepared statements or input validation routines. Any metacharacter such as a single quote, double dash, or UNION keyword passes through to the database engine.

Attack Vector

Exploitation occurs over the network through a standard HTTP POST request to the login endpoint. An attacker submits a crafted Username value containing SQL syntax, then observes responses or error states to extract data. Typical payloads use boolean-based, error-based, or UNION-based techniques to enumerate tables, exfiltrate credentials, or pivot to administrative access. No special tooling beyond an HTTP client is required, and automated scanners such as sqlmap can target the parameter directly. Public disclosure of the exploit on GitHub lowers the skill barrier for adversaries.

No verified proof-of-concept code is reproduced here. Refer to the GitHub CVE Issue Discussion and VulDB entry #325000 for technical specifics published by the reporter.

Detection Methods for CVE-2025-10712

Indicators of Compromise

HTTP POST requests to /index.php/Login/login containing SQL metacharacters such as ', --, UNION SELECT, or OR 1=1 in the Username field.
Repeated failed login attempts originating from a single source with anomalously long or encoded Username values.
Unexpected database errors, stack traces, or 500-series responses returned from the login endpoint.
Outbound database queries returning unusually large result sets shortly after requests to the login URL.

Detection Strategies

Inspect web server access logs for requests to /index.php/Login/login containing URL-encoded SQL syntax (%27, %20OR%20, %20UNION%20).
Deploy or update Web Application Firewall (WAF) rules to flag SQL injection patterns submitted to the login parameter.
Correlate authentication failures with database query latency spikes to surface blind injection probing.
Review application error logs for SQL syntax errors referencing the Username column or login query.

Monitoring Recommendations

Enable verbose logging on the Login controller and forward records to a centralized SIEM for query-pattern analytics.
Monitor for sudden increases in HTTP traffic volume to the login endpoint from single IP addresses or geographies not typical for the deployment.
Track database account activity for queries originating from the web application that read from administrative tables.

How to Mitigate CVE-2025-10712

Immediate Actions Required

Restrict access to the 07FLYCMS, 07FLY-CMS, and 07FlyCRM administrative interfaces to trusted IP ranges using network ACLs or a reverse proxy.
Deploy WAF signatures that block SQL injection patterns in POST parameters submitted to /index.php/Login/login.
Audit the affected database account permissions and revoke any rights beyond what the application requires.
Review historical web and database logs for prior exploitation attempts before applying restrictions.

Patch Information

At the time of disclosure, the vendor had not responded to disclosure attempts and no official patch was published. Operators should monitor vendor channels for updates and consider replacing the platform if no fix is released. Refer to the VulDB advisory #325000 for the latest vendor status.

Workarounds

Place the application behind a WAF configured with OWASP Core Rule Set signatures for SQL injection.
Implement reverse-proxy filtering to reject requests where the Username field contains SQL metacharacters or exceeds a reasonable length.
If source code access is available, modify the login query to use parameterized statements and apply strict input validation on the Username field.
Disable public exposure of the management interface until a vendor patch becomes available.

bash

# Example NGINX rule to block obvious SQL injection patterns in the login endpoint
location /index.php/Login/login {
    if ($args ~* "(union|select|insert|--|';|/\*)") {
        return 403;
    }
    if ($request_body ~* "(union|select|insert|--|';|/\*)") {
        return 403;
    }
    proxy_pass http://backend;
