CVE-2009-2359 in TekRADIUS
Summary
by MITRE
Multiple SQL injection vulnerabilities in TekRADIUS 3.0 allow context-dependent attackers to execute arbitrary SQL commands via (1) the GUI client, as demonstrated by input to the Browse Users text box in the Users tab; or (2) the command-line client, as demonstrated by a certain trcli -r command.

The vulnerability identified as CVE-2009-2359 represents a critical security flaw in TekRADIUS 3.0 software that exposes multiple pathways for SQL injection attacks. This vulnerability affects both the graphical user interface and command-line interfaces of the software, creating a comprehensive attack surface that adversaries can exploit to gain unauthorized access to underlying database systems. The vulnerability stems from insufficient input validation and sanitization within the application's data handling mechanisms, particularly when processing user-supplied data in the Browse Users text box and command-line parameters.
The technical implementation of this vulnerability demonstrates a classic SQL injection vector where attacker-controlled input is directly concatenated into SQL query strings without proper parameterization or escaping mechanisms. When users interact with the GUI client through the Browse Users functionality, or when utilizing the trcli -r command in the command-line interface, malicious input can manipulate the SQL execution flow to execute arbitrary database commands. This flaw operates under CWE-89 which specifically addresses SQL injection vulnerabilities, where the weakness allows attackers to bypass authentication, extract sensitive data, modify database contents, or even escalate privileges within the database environment. The context-dependent nature of this vulnerability means that successful exploitation requires specific conditions related to the application's operational environment and user interactions.
The operational impact of CVE-2009-2359 extends beyond simple data theft, potentially enabling full system compromise through database manipulation and unauthorized access to sensitive user information. Attackers could leverage this vulnerability to access user credentials, personal information, and other confidential data stored within the TekRADIUS database. The vulnerability's presence in both GUI and command-line interfaces increases the attack surface significantly, as different threat actors might exploit these pathways based on their technical capabilities and available tools. From an adversary perspective, this vulnerability aligns with ATT&CK technique T1190 which covers exploiting vulnerabilities in software applications, and T1071.005 which involves application layer protocol manipulation. The implications for organizations using TekRADIUS 3.0 include potential regulatory compliance violations, financial losses, reputational damage, and the need for immediate remediation efforts.
Mitigation strategies for this vulnerability must address both the immediate security gap and implement comprehensive input validation controls. Organizations should implement proper parameterized queries and prepared statements throughout the application codebase to prevent direct concatenation of user input into SQL commands. Input sanitization mechanisms must be strengthened to filter and validate all user-supplied data before processing, particularly in fields that directly influence database operations. The implementation of proper access controls and least privilege principles can limit the damage from successful exploitation attempts. Additionally, regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other applications. The vendor should provide immediate patches or updates that address the root cause of the SQL injection vulnerabilities, and organizations should implement network segmentation and monitoring to detect potential exploitation attempts. Security awareness training for administrators and developers can help prevent similar issues in future software development cycles, emphasizing the importance of secure coding practices and input validation as fundamental security controls.
