SQL Injection in ILIAS Repository Trash Table

Publication date: 2026-09-04

Last updated on: 2026-09-04

Assigner: VulnCheck

Description
ILIAS before versions 9.22, 10.10, and 11.3 contains a SQL injection vulnerability in the repository trash table where the table navigation sort field from HTTP requests is passed directly into the ORDER BY clause of a SQL query without validation against declared sortable columns. Authenticated users with write permission on any container can inject arbitrary SQL through the sort parameter, and because multi-statement execution is enabled in the database layer, stacked queries enable full database read and write access as well as administrator account takeover.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a SQL injection vulnerability in ILIAS versions before 9.22, 10.10, and 11.3. The issue occurs because the table navigation sort field from HTTP requests is passed directly into the ORDER BY clause of a SQL query without validation. Authenticated users with write permissions can inject arbitrary SQL through the sort parameter.

Detection Guidance

To detect this SQL injection vulnerability in ILIAS, inspect HTTP requests to the repository trash table for the sort parameter. Look for values that do not match the expected sortable columns. Check database logs for suspicious queries containing ORDER BY clauses with injected SQL. Use tools like SQLMap to test for SQL injection by sending crafted sort parameter values.

Impact Analysis

An attacker with write permissions can exploit this to execute arbitrary SQL queries. Due to stacked queries being enabled, this allows full database read and write access. This could lead to administrator account takeover and compromise of sensitive data stored in the ILIAS system.

Compliance Impact

This vulnerability could lead to unauthorized access or exposure of sensitive data, violating GDPR's data protection principles and HIPAA's security requirements. Organizations using vulnerable ILIAS versions may face compliance violations, legal penalties, and reputational damage due to potential data breaches.

Mitigation Strategies

Immediately update ILIAS to versions 9.22, 10.10, or 11.3 or later. Disable multi-statement execution in the database if possible. Restrict write permissions on containers to trusted users only. Implement input validation for the sort parameter to ensure it only accepts predefined sortable columns.
