CVE-2025-69562: Mobile Shop Management System SQLi Flaw

CVE-2025-69562 Overview

CVE-2025-69562 is a SQL Injection vulnerability [CWE-89] in code-projects Mobile Shop Management System 1.0. The flaw resides in the /insertmessage.php endpoint, where the userid parameter is passed into a SQL query without proper sanitization or parameterization. Unauthenticated remote attackers can inject arbitrary SQL statements through this parameter. Successful exploitation allows attackers to read, modify, or destroy database contents and potentially compromise the underlying application.

Critical Impact
Unauthenticated attackers can execute arbitrary SQL queries over the network, leading to full disclosure, modification, and deletion of database records.

Affected Products

code-projects Mobile Shop Management System 1.0
Deployments using the vulnerable /insertmessage.php endpoint
Web applications built on the Fabian Mobile Shop Management System codebase

Technical Details for CVE-2025-69562

Vulnerability Analysis

The vulnerability exists in the message insertion handler /insertmessage.php. The script accepts the userid parameter from client-supplied input and concatenates it directly into a SQL statement. Because the application does not use prepared statements or input validation, attackers can break out of the intended query context. The injection point is reachable without authentication, removing any prerequisite credentials or user interaction.

The vulnerability is classified under [CWE-89]: Improper Neutralization of Special Elements used in an SQL Command. Attackers can chain UNION-based payloads to exfiltrate data, time-based blind techniques to enumerate schema, or stacked queries depending on the database driver in use. Depending on database privileges, attackers may also write files or execute commands via database-specific functions.

Root Cause

The root cause is direct concatenation of untrusted input into a SQL query string in /insertmessage.php. The userid parameter is not validated, escaped, or bound through a parameterized query interface.

Attack Vector

An attacker sends a crafted HTTP request to /insertmessage.php containing a malicious value for the userid parameter. No authentication, privileges, or user interaction are required. The attack is delivered remotely over the network against the vulnerable web application. Refer to the GitHub Gist Code Commits and Gitee Issue Discussion for technical details.

// No verified public proof-of-concept code is available.
// The vulnerability is reachable by supplying SQL metacharacters
// in the `userid` parameter of POST/GET requests to /insertmessage.php.

Detection Methods for CVE-2025-69562

Indicators of Compromise

HTTP requests to /insertmessage.php containing SQL metacharacters such as single quotes, UNION SELECT, OR 1=1, or comment sequences (--, #) in the userid parameter.
Unexpected database errors logged from the Mobile Shop Management System application referencing the userid value.
Abnormal outbound database queries or large result sets initiated by the web application user.

Detection Strategies

Deploy web application firewall (WAF) rules to flag SQL injection patterns targeting the userid parameter on /insertmessage.php.
Inspect web server access logs for non-numeric or encoded payloads in userid query string or POST body fields.
Correlate web request anomalies with database server query logs to identify injected statements.

Monitoring Recommendations

Monitor for spikes in 500-level HTTP responses originating from /insertmessage.php.
Alert on database accounts used by the web application executing INFORMATION_SCHEMA, sleep(), or benchmark() queries.
Track repeated requests from a single source against the vulnerable endpoint within short time windows.

How to Mitigate CVE-2025-69562

Immediate Actions Required

Restrict public access to /insertmessage.php using network controls or WAF rules until a patch is applied.
Audit the database account used by the application and revoke unnecessary privileges such as FILE or SUPER.
Review application and database logs for prior exploitation activity referencing the userid parameter.

Patch Information

No official vendor patch or advisory has been published for code-projects Mobile Shop Management System 1.0 at the time of disclosure. Organizations running this application should consider replacing the affected source files with code that uses parameterized queries, or migrating off the unmaintained product.

Workarounds

Apply a virtual patch via WAF to reject requests containing SQL metacharacters in the userid parameter.
Modify /insertmessage.php to enforce strict type checking, ensuring userid accepts only integer values.
Refactor the database access layer to use prepared statements with bound parameters via PDO or mysqli.
