CVE-2026-93980: Internship Management System SQL Injection

CVE-2026-93980 is a SQL injection vulnerability in code-projects Internship Management System 1.0 affecting the admin login form. Attackers can exploit the Password parameter to manipulate database queries. This post covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2026-93980 Overview

CVE-2026-93980 is a SQL injection vulnerability in code-projects Internship Management System 1.0. The flaw resides in the /admin/login.php file, specifically in the handling of the Password argument within the Admin Login Form component. Remote attackers can manipulate the Password parameter to inject arbitrary SQL statements against the backend database. The exploit has been disclosed publicly, increasing the risk of opportunistic attacks against exposed installations. The weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Unauthenticated remote attackers can inject SQL commands through the admin login form, potentially bypassing authentication and accessing or modifying database contents.

Technical Details for CVE-2026-93980

Vulnerability Analysis

The vulnerability affects the administrator authentication workflow in Internship Management System 1.0. The Password field submitted to /admin/login.php is concatenated into a SQL query without proper sanitization or parameterization. An attacker can craft a malicious payload that alters the query logic, enabling authentication bypass or extraction of sensitive data. Because the endpoint is reachable pre-authentication over the network, exploitation requires no valid credentials or user interaction.

Root Cause

The root cause is improper neutralization of user-controlled input passed to the database layer. The application does not use prepared statements or parameterized queries for the login form. Input concatenation into raw SQL allows attacker-supplied metacharacters to break out of the intended string context and modify query semantics.

Attack Vector

The attack vector is network-based and targets the admin login page. An attacker submits crafted POST data to /admin/login.php, placing SQL syntax inside the Password parameter. Successful exploitation can return a truthy authentication result, dump database contents through boolean- or time-based techniques, or manipulate stored records. Public proof-of-concept material is referenced in the GitHub CVE Documentation and VulDB CVE-2026-93980 Details.

No verified exploit code is reproduced here. See the referenced advisories for technical proof-of-concept details.

Detection Methods for CVE-2026-93980

Indicators of Compromise

POST requests to /admin/login.php containing SQL metacharacters such as single quotes, OR 1=1, UNION SELECT, or comment sequences (--, #) in the Password field.
Repeated failed login attempts followed by an unexpectedly successful admin session from the same source IP.
Anomalous outbound database queries or long-running queries originating from the login endpoint, indicative of time-based blind SQL injection.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the Password parameter of /admin/login.php for SQL injection signatures.
Enable database query logging and alert on syntactically unusual queries generated by the login handler.
Correlate authentication events with source IP reputation feeds to surface admin logins from suspicious hosts.

Monitoring Recommendations

Monitor HTTP access logs for URI patterns targeting /admin/login.php with unusually large or encoded Password values.
Track the frequency of admin login attempts and alert on brute-force or enumeration patterns.
Ingest web server, WAF, and database logs into a centralized analytics platform for correlated detection of injection attempts.

How to Mitigate CVE-2026-93980

Immediate Actions Required

Restrict network access to the /admin/ directory using IP allowlisting or VPN-only access until a patch is available.
Deploy WAF rules specifically blocking SQL injection payloads targeting the Password parameter of the login form.
Audit the admin account and database for signs of unauthorized access or data modification.

Patch Information

No official vendor patch has been published in the referenced advisories at the time of writing. Users of code-projects Internship Management System 1.0 should monitor the Code Projects Resource Hub and the VulDB CVE-2026-93980 Details page for remediation updates.

Workarounds

Modify /admin/login.php to use parameterized queries or prepared statements (for example, PDO with bound parameters) instead of string concatenation.
Apply server-side input validation that rejects non-printable characters and SQL metacharacters in authentication fields.
Enforce least-privilege database accounts so the web application cannot execute administrative SQL operations.
Consider decommissioning the deployment if it exposes production data, given the absence of a vendor fix.

bash

# Example: restrict access to admin directory via Apache .htaccess
<Directory "/var/www/html/admin">
    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
</Directory>
