CVE-2026-94032: Leave Management System 1.0 SQLi Vulnerability

CVE-2026-94032 Overview

CVE-2026-94032 is a SQL injection vulnerability in itsourcecode Leave Management System 1.0. The flaw resides in the /module/department/index.php file and stems from improper handling of the ID parameter. Attackers can manipulate this parameter to inject arbitrary SQL statements into the backend database query.

The issue is remotely exploitable and requires only low-level privileges. A public exploit has been disclosed, increasing the likelihood of opportunistic attacks against exposed installations. The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Remote attackers with low privileges can extract, modify, or delete database records by injecting SQL through the ID parameter on the department module.

Technical Details for CVE-2026-94032

Vulnerability Analysis

The vulnerability affects the department management module in itsourcecode Leave Management System 1.0. The index.php script under /module/department/ accepts an ID parameter from the request. This value is concatenated directly into a SQL query without parameterization or sanitization.

An authenticated attacker with low privileges can supply crafted SQL syntax through the ID argument. The database engine then executes the injected payload alongside the intended query. This allows reading arbitrary tables, modifying records, or in some configurations executing administrative database commands.

Since the attack occurs over the network and the exploit has been published, defenders should treat any internet-facing deployment as reachable by opportunistic scanning.

Root Cause

The root cause is the absence of prepared statements or input validation on the ID parameter within /module/department/index.php. User-supplied input flows directly into a dynamically constructed SQL string, matching the [CWE-74] injection pattern.

Attack Vector

Exploitation requires network access to the application and a valid low-privileged session. The attacker submits an HTTP request to /module/department/index.php with a malicious ID value containing SQL metacharacters. No user interaction is required beyond issuing the request.

Refer to the VulDB CVE-2026-94032 entry and the GitHub issue tracker for technical details of the disclosed proof of concept.

Detection Methods for CVE-2026-94032

Indicators of Compromise

HTTP requests to /module/department/index.php containing SQL syntax such as UNION SELECT, OR 1=1, --, ;, or encoded variants in the ID parameter.
Web server or PHP error logs referencing SQL syntax errors originating from the department module.
Unexpected database read errors, aborted queries, or spikes in query duration tied to the department table.

Detection Strategies

Inspect web access logs for anomalous ID values that include non-numeric characters, quote marks, or SQL keywords.
Deploy web application firewall (WAF) rules that flag SQL injection payloads targeting the /module/department/ path.
Correlate authenticated session activity with database queries that touch tables beyond the department scope.

Monitoring Recommendations

Enable verbose query logging on the backend MySQL/MariaDB instance and alert on syntactically malformed statements.
Baseline normal request patterns to the leave management application and alert on deviations in parameter structure.
Monitor outbound connections from the web server that could indicate data exfiltration following successful injection.

How to Mitigate CVE-2026-94032

Immediate Actions Required

Restrict network access to the Leave Management System, limiting reachability to trusted management networks or VPN users.
Audit account provisioning and disable unused low-privilege accounts that could be leveraged to reach the vulnerable endpoint.
Deploy WAF signatures that block SQL injection attempts targeting /module/department/index.php.

Patch Information

No official vendor patch has been referenced in the CVE record at time of publication. Consult the IT Source Code project site and the VulDB submission tracker for updates on remediation guidance.

Workarounds

Apply server-side input validation to enforce a strict numeric type on the ID parameter before it reaches the database layer.
Refactor the query in /module/department/index.php to use prepared statements with bound parameters instead of string concatenation.
Run the application behind a reverse proxy that rejects requests with SQL metacharacters in query strings.
Restrict database account privileges used by the web application to the minimum required for the department module.
