The vulnerability identified as CVE-2006-0692 represents a critical SQL injection flaw in the Carey Briggs PHP/MYSQL Timesheet version 1 and 2 applications. This vulnerability resides in the input validation mechanisms of two key files within the timesheet application: index.php and changehrs.php. The affected parameters include yr, month, day, and job which are processed without adequate sanitization or parameterization, creating a pathway for malicious actors to manipulate the underlying database queries. This vulnerability falls under the CWE-89 category of SQL Injection, which is classified as a high-severity weakness in the Common Weakness Enumeration catalog. The ATT&CK framework categorizes this as a Database Injection technique under the broader category of Command and Control.
The technical exploitation of this vulnerability occurs when remote attackers manipulate the yr, month, day, and job parameters through HTTP requests to the vulnerable application. These parameters are directly incorporated into SQL queries without proper input validation or parameter binding, allowing attackers to inject malicious SQL code that gets executed by the database engine. When an attacker submits crafted input through these parameters, the application's SQL queries become vulnerable to manipulation, potentially enabling unauthorized database access, data extraction, modification, or deletion. The vulnerability affects both index.php and changehrs.php files, suggesting a widespread impact across the application's core functionality for viewing and modifying time entries.
The operational impact of this vulnerability extends beyond simple data compromise, as it provides attackers with the capability to perform extensive database operations. Successful exploitation could allow attackers to extract sensitive employee time data, modify existing records, insert malicious entries, or even escalate privileges within the database system. The vulnerability's remote nature means that attackers do not require local system access or physical presence to exploit the flaw, making it particularly dangerous in networked environments. Organizations utilizing this timesheet application face significant risk of unauthorized access to their time tracking databases, potentially exposing confidential employee information and compromising business operations.
Mitigation strategies for CVE-2006-0692 should focus on implementing proper input validation and parameterized queries to prevent SQL injection attacks. The most effective approach involves using prepared statements or parameterized queries with proper input sanitization for all database interactions. Organizations should immediately upgrade to patched versions of the Carey Briggs PHP/MYSQL Timesheet application or implement input validation measures that filter or escape special characters in the yr, month, day, and job parameters. Additionally, implementing web application firewalls and database activity monitoring can provide additional layers of protection. The vulnerability demonstrates the critical importance of secure coding practices and input validation, aligning with industry standards such as OWASP Top Ten and the Secure Coding guidelines that emphasize the need for proper parameter handling in database operations.
