CVE-2026-104625: Simple Loan Management System SQLi Flaw

CVE-2026-104625 is a SQL injection vulnerability in CodeAstro Simple Loan Management System 1.0 affecting the /admin/index.php file. Attackers can exploit the g_name parameter remotely to manipulate database queries. This article covers technical details, affected versions, security impact, and mitigation strategies.

CVE-2026-104625 Overview

CVE-2026-104625 is a SQL injection vulnerability in CodeAstro Simple Loan Management System 1.0. The flaw resides in the /admin/index.php script, where the g_name parameter is passed to a database query without proper sanitization. Attackers can manipulate the parameter to inject arbitrary SQL statements against the backend database. The weakness is tracked under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). Public exploit details have been released, lowering the barrier to attack. Remote exploitation is possible, though it requires low-privileged authentication to the administrative interface.

Critical Impact
Authenticated remote attackers can inject SQL through the g_name parameter in /admin/index.php, enabling unauthorized read, modification, or disclosure of loan management data.

Technical Details for CVE-2026-104625

Vulnerability Analysis

The vulnerability is a classic SQL injection in the administrative interface of CodeAstro Simple Loan Management System 1.0. The g_name HTTP parameter sent to /admin/index.php is concatenated directly into a SQL statement without parameterization or escaping. By supplying crafted input containing SQL metacharacters, an authenticated attacker alters the query logic executed by the backend. Depending on the underlying query, the attacker can enumerate database schema, extract credentials, modify loan records, or escalate access within the application. The flaw is categorized as CWE-74, reflecting the application's failure to neutralize special elements before passing data to a downstream SQL interpreter.

Root Cause

The root cause is unsafe handling of the g_name request parameter. The application concatenates user-controlled input into a SQL query string rather than using prepared statements with bound parameters. No server-side validation, type enforcement, or encoding is applied before the value reaches the database driver.

Attack Vector

Exploitation occurs over the network against the administrative panel. An attacker holding low-privileged credentials sends a crafted HTTP request to /admin/index.php with a malicious g_name value. Technical details and a public reference are available via the GitHub Issue Discussion and the VulDB CVE-2026-104625 entry.

Detection Methods for CVE-2026-104625

Indicators of Compromise

HTTP requests to /admin/index.php containing SQL metacharacters such as single quotes, UNION SELECT, OR 1=1, or inline comments in the g_name parameter.
Web server access logs showing unusually long or encoded g_name values from a limited set of source addresses.
Database error messages or 500-series responses correlated with requests targeting the g_name parameter.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the g_name parameter for SQL injection payload patterns.
Enable database query logging and alert on suspicious statements originating from the loan management application's service account.
Correlate anomalous administrative login activity with downstream query volume to spot post-authentication exploitation attempts.

Monitoring Recommendations

Monitor authentication logs for administrative accounts, especially from unexpected geolocations or user agents.
Baseline normal query shapes issued by /admin/index.php and alert on deviations such as INFORMATION_SCHEMA lookups or UNION-based reads.
Track outbound data volume from the database host to detect bulk extraction attempts.

How to Mitigate CVE-2026-104625

Immediate Actions Required

Restrict network access to /admin/index.php using IP allow-listing or VPN gating until a fix is applied.
Rotate credentials for all administrative accounts of the Simple Loan Management System.
Review database audit logs for prior exploitation attempts referencing the g_name parameter.

Patch Information

No official vendor patch has been published at the time of writing. Consult the CodeAstro Security Resource and the VulDB Vulnerability #412924 record for updates on remediation availability.

Workarounds

Place the application behind a WAF with signatures that block SQL injection patterns targeting the g_name parameter.
Enforce least-privilege database accounts so the application cannot read system catalogs or write outside required tables.
If feasible, modify the vulnerable query in /admin/index.php to use prepared statements with bound parameters and server-side input validation.
