CVE-2008-0133 in Tribisur
Summary
by MITRE
Multiple SQL injection vulnerabilities in Tribisur 2.1 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) id parameter to cat_main.php and the (2) cat parameter to forum.php in a liste action.

The vulnerability described in CVE-2008-0133 represents a critical security flaw in Tribisur version 2.1 and earlier, exposing the application to remote SQL injection attacks that can lead to complete system compromise. This vulnerability manifests through two distinct attack vectors within the application's web interface, specifically targeting parameters in different PHP scripts that handle user input without proper sanitization or validation. The first vector occurs in the cat_main.php script where the id parameter is processed, while the second vector exists in forum.php within the liste action where the cat parameter is susceptible to malicious input manipulation.
The technical implementation of this vulnerability stems from the application's failure to properly escape or validate user-supplied input before incorporating it into SQL query constructions. When attackers submit malicious SQL payloads through either the id parameter in cat_main.php or the cat parameter in forum.php, the application directly concatenates these inputs into database queries without appropriate sanitization measures. This design flaw aligns with CWE-89 which specifically addresses SQL injection vulnerabilities where untrusted data is incorporated into SQL commands without proper validation or escaping mechanisms. The vulnerability demonstrates a classic lack of input validation and output encoding practices that are fundamental to preventing injection attacks in web applications.
The operational impact of this vulnerability extends far beyond simple data theft, as remote attackers can execute arbitrary SQL commands against the underlying database system. Successful exploitation could enable attackers to retrieve sensitive information including user credentials, personal data, and application configuration details. The attack surface is particularly concerning given that both vulnerable parameters are accessible through standard web interface interactions, requiring no special privileges or local access. Attackers could potentially escalate their privileges, modify or delete database records, and in some cases gain complete control over the database server itself. This vulnerability directly maps to several ATT&CK techniques including T1071.004 for application layer protocol usage and T1046 for network service scanning, as attackers would need to identify and exploit these specific parameters to achieve their objectives.
Mitigation strategies for this vulnerability require immediate implementation of proper input validation and parameterized query execution throughout the application codebase. The most effective defense involves replacing direct SQL query construction with prepared statements or parameterized queries that separate SQL command structure from user data. Additionally, implementing proper input sanitization routines and output encoding mechanisms will prevent malicious payloads from being interpreted as executable SQL code. Security patches should be deployed immediately to update Tribisur to versions that address these injection vulnerabilities, while network-level protections such as web application firewalls can provide additional defense-in-depth measures. Regular security auditing and code reviews should be implemented to identify and remediate similar vulnerabilities throughout the application lifecycle, following established security frameworks and best practices for preventing injection attacks.
