CVE-2026-9574: Student Transcript Processing SQLi Flaw

CVE-2026-9574 Overview

CVE-2026-9574 is a SQL injection vulnerability in itsourcecode Student Transcript Processing System 1.0. The flaw resides in /admin/modules/student/trans.php, where the studentId and cid parameters are passed to backend database queries without proper sanitization. Remote attackers can manipulate these arguments to inject arbitrary SQL statements against the application database. The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and requires no authentication or user interaction. A public exploit has been disclosed, increasing the likelihood of opportunistic attacks against exposed instances.

Critical Impact

Unauthenticated remote attackers can extract, modify, or delete student transcript records by injecting SQL through the studentId or cid parameters.

Technical Details for CVE-2026-9574

Vulnerability Analysis

The vulnerability is a remote SQL injection in the administrative transcript module of itsourcecode Student Transcript Processing System 1.0. The script trans.php accepts studentId and cid parameters directly from HTTP requests. These values flow into SQL queries without parameterization or input filtering. An attacker can append SQL operators, UNION clauses, or stacked queries to alter query logic. Successful exploitation grants read or write access to records in the underlying database.

The attack vector is network-based and requires no privileges or user interaction. Because the affected endpoint is part of the admin module, exploitation can expose privileged administrative data. The public availability of exploit details lowers the barrier for unauthenticated attackers. See the GitHub Issue Discussion and VulDB Vulnerability #365633 for additional context.

Root Cause

The root cause is improper neutralization of special elements in SQL statements [CWE-74]. The application concatenates user-supplied studentId and cid values directly into SQL queries instead of using prepared statements or parameterized queries. No server-side input validation or escaping is applied before query execution.

Attack Vector

An attacker sends a crafted HTTP request to /admin/modules/student/trans.php containing malicious SQL syntax in the studentId or cid parameter. The injected payload executes within the database context. Common outcomes include authentication bypass, exfiltration of transcript and credential records, and modification or deletion of stored data.

No verified exploit code is referenced in the advisory. The vulnerability mechanism is documented in the VulDB Vulnerability #365633 entry.

Detection Methods for CVE-2026-9574

Indicators of Compromise

• HTTP requests to /admin/modules/student/trans.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or ; in the studentId or cid parameters.
• Database error messages or unexpected query results returned to clients accessing the transcript module.
• Unusual outbound data volumes from the web application or database server following requests to the affected endpoint.

Detection Strategies

• Deploy a web application firewall (WAF) rule that inspects studentId and cid parameters for SQL injection signatures.
• Enable verbose query logging on the database server and alert on syntactically anomalous queries originating from the transcript module.
• Review web server access logs for repeated requests to /admin/modules/student/trans.php with encoded payloads or boolean-based probing patterns.

Monitoring Recommendations

• Monitor administrative endpoints for unauthenticated access attempts and burst request patterns indicative of automated SQL injection tooling.
• Alert on database authentication failures, schema enumeration queries, and information_schema access from the application service account.
• Correlate web request anomalies with database query logs to identify exploitation in progress.

How to Mitigate CVE-2026-9574

Immediate Actions Required

• Restrict network access to /admin/modules/student/trans.php to trusted administrative IP ranges until a fix is applied.
• Audit the database for unauthorized record modifications, new administrative accounts, or evidence of data exfiltration.
• Rotate database credentials and any administrative passwords stored in the affected system.

Patch Information

No official vendor patch is referenced in the advisory at the time of publication. Refer to the IT Source Code Resource site for vendor updates and to the VulDB Vulnerability #365633 entry for ongoing tracking.

Workarounds

• Replace direct query concatenation in trans.php with parameterized queries or prepared statements using PDO or MySQLi with bound parameters.
• Enforce strict server-side input validation on studentId and cid, accepting only the expected numeric or alphanumeric character set.
• Place the application behind a WAF configured with SQL injection rule sets and block requests containing SQL metacharacters in the affected parameters.
• Apply least-privilege principles to the database account used by the application, removing DROP, ALTER, and administrative rights where not required.
