CVE-2026-9575: Student Transcript Processing SQLi Flaw

CVE-2026-9575 Overview

CVE-2026-9575 is a SQL injection vulnerability in itsourcecode Student Transcript Processing System 1.0. The flaw resides in /admin/modules/class/index.php?view=view, where the ID parameter is passed to backend database queries without proper sanitization. Remote attackers can manipulate the ID argument to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed installations. The issue is classified under CWE-74 (Improper Neutralization of Special Elements in Output).

Critical Impact

Unauthenticated remote attackers can manipulate database queries through the ID parameter, potentially exposing student records, transcripts, and administrative credentials.

Affected Products

Technical Details for CVE-2026-9575

Vulnerability Analysis

The vulnerability exists in the administrative class management module of the Student Transcript Processing System. When a user requests /admin/modules/class/index.php?view=view, the application accepts an ID parameter and incorporates it directly into a SQL query. Because the value is not parameterized or escaped, attackers can break out of the intended query context and append arbitrary SQL.

The attack vector is the network, requires no authentication, and requires no user interaction. Successful exploitation can yield read and write access to the underlying database, depending on the privileges of the database user configured for the application. The public availability of exploitation details raises the operational risk for any exposed deployment.

Root Cause

The root cause is improper neutralization of user-supplied input before it is used in a SQL statement. The ID parameter is concatenated into the query string rather than bound through a prepared statement. This pattern is consistent with CWE-74 and the more specific CWE-89 (SQL Injection).

Attack Vector

An attacker sends a crafted HTTP GET request to the vulnerable endpoint, supplying SQL syntax in the ID parameter. Typical exploitation patterns include union-based extraction to enumerate tables, boolean-based blind injection to confirm data values, and time-based blind injection where output is not reflected. Because the endpoint sits under /admin/, attackers may also target session-related tables or insert administrative accounts. See the public proof-of-concept on GitHub and the VulDB entry for technical details.

Detection Methods for CVE-2026-9575

Indicators of Compromise

• HTTP requests to /admin/modules/class/index.php?view=view containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the ID parameter.
• Web server access logs showing unusually long or URL-encoded ID values originating from unexpected source IPs.
• Database error messages referencing syntax errors triggered from the class module endpoint.
• Unexpected administrative account creation or modifications to transcript records in application audit tables.

Detection Strategies

• Deploy web application firewall rules that flag SQL keywords and tautology patterns in the ID query parameter of the affected path.
• Enable verbose query logging on the backend database and alert on queries originating from the class/index.php script that contain UNION, INFORMATION_SCHEMA, or stacked statements.
• Correlate failed authentication attempts with subsequent successful admin actions in application logs.

Monitoring Recommendations

• Monitor outbound database traffic for anomalous data volumes that could indicate bulk extraction.
• Alert on HTTP 500 responses from /admin/modules/class/index.php as these often signal injection probing.
• Track newly created database users, roles, or privilege grants on the transcript database.

How to Mitigate CVE-2026-9575

Immediate Actions Required

• Restrict access to the /admin/ directory using IP allowlisting or VPN-only access until a patched build is available.
• Audit the database account used by the application and reduce its privileges to the minimum required for normal operation.
• Review web server and database logs for prior exploitation attempts against index.php?view=view.
• Rotate administrative credentials and database passwords if compromise is suspected.

Patch Information

No vendor patch is currently referenced in the NVD entry for CVE-2026-9575. Operators should monitor the itsourcecode website and the VulDB advisory for vendor updates. Until an official fix is released, apply the workarounds below.

Workarounds

• Implement a web application firewall rule that blocks non-numeric input for the ID parameter on the affected endpoint.
• Modify the application source to use parameterized queries or PDO prepared statements for all references to the ID value.
• Cast the ID parameter to an integer in PHP before it reaches the SQL layer, for example using intval($_GET['ID']).
• Disable the administrative module entirely if it is not in active use.

# Example WAF rule (ModSecurity) to block SQLi in the ID parameter
SecRule REQUEST_URI "@contains /admin/modules/class/index.php" \
    "chain,id:1009575,phase:2,deny,status:403,msg:'CVE-2026-9575 SQLi attempt'"
    SecRule ARGS:ID "!@rx ^[0-9]+$" "t:none"
