CVE-2026-108928: Online Admission System SQL Injection Flaw

CVE-2026-108928 is a SQL injection vulnerability in itsourcecode Online Admission System 1.0 affecting the /admin/sum.php file. Attackers can remotely exploit this flaw to manipulate database queries. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2026-108928 Overview

CVE-2026-108928 is a SQL injection vulnerability in itsourcecode Online Admission System 1.0. The flaw resides in the /admin/sum.php script, where the ID parameter is passed to the backend database without proper sanitization. Attackers with low-privilege authenticated access can manipulate the ID argument to inject arbitrary SQL statements. The vulnerability is remotely exploitable over the network, and a public exploit disclosure increases the likelihood of opportunistic use. The weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output). Impact is limited to low confidentiality, integrity, and availability loss against the affected database tables.

Critical Impact
Authenticated remote attackers can inject arbitrary SQL through the ID parameter in /admin/sum.php, exposing administrative database contents.

Affected Products

itsourcecode Online Admission System 1.0
Deployments exposing /admin/sum.php to untrusted networks
Any downstream fork reusing the vulnerable sum.php handler

Technical Details for CVE-2026-108928

Vulnerability Analysis

The vulnerability affects the administrative endpoint /admin/sum.php in itsourcecode Online Admission System 1.0. The ID request parameter is concatenated into a SQL statement without parameterization or input validation. An attacker holding low-level credentials can submit crafted values that break out of the intended query context. Successful exploitation enables reading, modifying, or deleting records in the backing database. Because the endpoint lives under /admin/, exposure of administrative data and privilege-related tables is possible. Public disclosure of the exploit raises the probability of automated scanning and reuse by low-skill actors.

Root Cause

The root cause is improper neutralization of special elements passed to the database layer [CWE-74]. The sum.php handler trusts the client-supplied ID value and inserts it directly into a SQL query string. No prepared statements, bound parameters, or input allowlisting exist on this code path.

Attack Vector

An authenticated attacker sends an HTTP request to /admin/sum.php with a tampered ID parameter containing SQL metacharacters. The server executes the attacker-controlled fragment against the backend database. No user interaction is required beyond the attacker's own request. Public proof-of-concept material has been referenced in the GitHub Issue Discussion and VulDB CVE-2026-108928 entries.

No verified exploit code is reproduced here. Refer to the external references for technical details on the injection string construction.

Detection Methods for CVE-2026-108928

Indicators of Compromise

HTTP requests to /admin/sum.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or ; in the ID parameter
Unexpected database errors or stack traces originating from sum.php in web server logs
Administrative session activity from unfamiliar source IP addresses targeting the /admin/ path

Detection Strategies

Deploy web application firewall (WAF) signatures that identify SQL injection patterns on the ID query parameter
Enable database query logging and alert on anomalous UNION-based or boolean-based payloads reaching the admissions schema
Correlate authenticated administrator sessions with abnormal volumes of requests to sum.php

Monitoring Recommendations

Forward web, application, and database logs into a centralized analytics platform for cross-source correlation
Baseline normal /admin/sum.php traffic and alert on deviations in request volume or payload entropy
Monitor for new administrative account creation or privilege changes following suspicious sum.php activity

How to Mitigate CVE-2026-108928

Immediate Actions Required

Restrict network access to /admin/ paths using IP allowlists, VPN gating, or reverse proxy authentication
Rotate administrative credentials and audit recent sessions on the admissions application
Deploy WAF rules blocking SQL metacharacters on the ID parameter of sum.php until code-level remediation is applied

Patch Information

No vendor patch has been published in the referenced advisories. Review the VulDB Vulnerability #416751 record and the IT Source Code Resource for update availability. Operators should treat the application as unpatched and apply code-level fixes manually by converting the affected query to a prepared statement with bound parameters.

Workarounds

Replace the raw SQL in sum.php with parameterized queries or an ORM binding for the ID field
Enforce strict server-side input validation on ID, accepting only expected numeric values
Run the application database account with least privilege, denying DROP, ALTER, and cross-schema access

bash

# Example WAF rule concept (ModSecurity) blocking SQLi on the ID parameter
SecRule ARGS:ID "@detectSQLi" \
    "id:1082026108928,phase:2,deny,status:403,\
