CVE-2025-11593: Gym Management System SQLi Vulnerability

CVE-2025-11593 Overview

CVE-2025-11593 is a SQL injection vulnerability in CodeAstro Gym Management System 1.0. The flaw resides in /admin/actions/delete-equipment.php, where the ID parameter is passed to a database query without proper sanitization. Remote attackers with low-privileged access can manipulate the parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the risk of opportunistic attacks against exposed installations. The vulnerability is tracked under [CWE-89] (SQL Injection) and [CWE-74] (Improper Neutralization of Special Elements in Output).

Critical Impact
Authenticated remote attackers can execute arbitrary SQL queries against the application database, leading to data disclosure, modification, or deletion of gym management records.

Technical Details for CVE-2025-11593

Vulnerability Analysis

The vulnerability exists in the equipment deletion handler at /admin/actions/delete-equipment.php. The script accepts an ID parameter via HTTP request and concatenates it directly into a SQL DELETE or SELECT statement without parameterization or input validation. An authenticated attacker can supply crafted input that breaks out of the intended query context. This enables execution of attacker-controlled SQL statements within the application's database session. The affected workflow handles equipment records, but the resulting SQL execution context typically extends to the entire application database.

Root Cause

The root cause is improper neutralization of special characters in SQL commands ([CWE-89]). The PHP code constructs SQL queries through string concatenation with user-supplied data instead of using prepared statements with bound parameters. No type coercion or whitelist validation is applied to the ID argument before it reaches the database driver.

Attack Vector

Exploitation requires network access to the admin interface and low-privileged authenticated access. An attacker submits a malicious value in the ID parameter when invoking the delete-equipment endpoint. The injected SQL is executed by the backend database with the application's privileges, allowing extraction or modification of arbitrary tables. No user interaction beyond the attacker's own request is required.

Detection Methods for CVE-2025-11593

Indicators of Compromise

HTTP requests to /admin/actions/delete-equipment.php containing SQL metacharacters such as single quotes, UNION, SLEEP(, --, or /* in the ID parameter.
Unexpected administrative authentication events followed by requests to the delete-equipment endpoint from the same source IP.
Database error messages or anomalous query execution times correlating with requests to the vulnerable endpoint.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the ID parameter on the affected endpoint for SQL injection signatures.
Enable database query logging and alert on DELETE or SELECT statements containing unexpected boolean conditions, stacked queries, or time-based functions.
Correlate web server access logs with database audit logs to identify abnormal query patterns originating from admin actions.

Monitoring Recommendations

Monitor for repeated 500-class responses or query execution anomalies on /admin/actions/.
Track admin account login frequency and the volume of equipment-deletion actions per session.
Alert on outbound database connections or large result-set extractions tied to the gym management application.

How to Mitigate CVE-2025-11593

Immediate Actions Required

Restrict network access to the admin interface using IP allowlisting or VPN gating until a vendor patch is available.
Rotate administrative credentials and review recent admin session activity for signs of abuse.
Audit the equipment and related database tables for unexpected deletions or modifications.

Patch Information

No vendor patch has been published for CodeAstro Gym Management System 1.0 at the time of NVD publication. Operators should consult the CodeAstro Security Resource and the VulDB Entry #327914 for updates. Until a fix is released, treat the application as vulnerable in any internet-exposed deployment.

Workarounds

Modify /admin/actions/delete-equipment.php to cast the ID parameter to an integer before use, for example $id = (int)$_GET['ID'];.
Refactor the affected query to use prepared statements with bound parameters via PDO or MySQLi.
Place the application behind a WAF with SQL injection signatures enabled for all /admin/actions/ paths.
Disable or remove the equipment-management module if it is not in active use.

bash

# Example WAF rule (ModSecurity) to block SQLi patterns on the affected endpoint
SecRule REQUEST_URI "@beginsWith /admin/actions/delete-equipment.php" \
  "chain,deny,status:403,id:1011593,msg:'CVE-2025-11593 SQLi attempt'"
  SecRule ARGS:ID "@detectSQLi" "t:none"
