CVE-2010-1583 in TaskFreak!
Summary
by MITRE
SQL injection vulnerability in the loadByKey function in the TznDbConnection class in tzn_mysql.php in Tirzen (aka TZN) Framework 1.5, as used in TaskFreak! before 0.6.3, allows remote attackers to execute arbitrary SQL commands via the username field in a login action.

The CVE-2010-1583 vulnerability represents a critical SQL injection flaw within the Tirzen (TZN) Framework version 1.5, specifically affecting TaskFreak! versions prior to 0.6.3. This vulnerability resides in the TznDbConnection class within the tzn_mysql.php file and manifests through the loadByKey function, which processes user authentication requests. The flaw enables remote attackers to manipulate database queries by exploiting improper input validation in the username field during login operations, potentially leading to unauthorized database access and command execution.
The technical implementation of this vulnerability stems from inadequate sanitization of user input within the authentication flow. When a user attempts to log in, the system processes the username parameter through the loadByKey function without proper parameterization or input validation. This allows attackers to inject malicious SQL code that bypasses normal authentication mechanisms and directly manipulates the database query structure. The vulnerability follows the classic SQL injection pattern where user-controllable input is concatenated directly into SQL statements rather than being properly escaped or parameterized, making it susceptible to exploitation through crafted malicious input.
From an operational perspective, this vulnerability poses significant risks to affected systems as it enables attackers to execute arbitrary SQL commands on the underlying database server. Successful exploitation could result in data theft, unauthorized account access, privilege escalation, and potential system compromise. Attackers could extract sensitive information such as user credentials, personal data, and system configurations, while also potentially gaining the ability to modify or delete database records. The remote nature of this vulnerability means that attackers do not require physical access to the system, making it particularly dangerous for web applications that are publicly accessible.
The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws in software applications. According to the MITRE CWE database, this represents a common weakness that occurs when application code incorporates user input directly into SQL queries without proper validation or escaping mechanisms. From an ATT&CK framework perspective, this vulnerability maps to techniques involving command and control through database manipulation and credential access through authentication bypass methods. The attack surface is further expanded by the fact that this vulnerability affects a widely used framework component, potentially compromising multiple applications that rely on the Tirzen Framework for their database operations.
Mitigation strategies for CVE-2010-1583 should prioritize immediate patching of affected TaskFreak! installations to version 0.6.3 or later, which contains the necessary security fixes. Organizations should implement proper input validation and parameterized queries throughout their authentication systems, ensuring that all user inputs are properly sanitized before being processed by database operations. Additional defensive measures include implementing web application firewalls, monitoring database access logs for suspicious activities, and conducting regular security assessments of application code to identify similar vulnerabilities. The fix should involve proper parameter binding or escaping mechanisms that prevent malicious SQL code from being executed within the database context, thereby eliminating the attack vector that enables this specific SQL injection vulnerability.
