CVE-2006-2062 in Leadhound Full
Summary
by MITRE
Multiple SQL injection vulnerabilities in Leadhound Full and LITE 2.1, and probably the Network Version "Full Version", allow remote attackers to execute arbitrary SQL commands via the (1) banner parameter in agent_links.pl; the offset parameter in (2) agent_links.pl, (3) agent_transactions.pl, (4) agent_subaffiliates.pl, and (5) agent_summary.pl; the camp_id parameter in (6) agent_transactions_csv.pl, (7) agent_subaffiliates.pl, and (8) agent_camp_det.pl; the (9) login parameter in agent_commission_statement.pl; the logged parameter in (10) agent_commission_statement.pl and (11) agent_camp_det.pl; the (12) agent_id parameter in agent_commission_statement.pl; and the (13) sub parameter in unspecified files.

The vulnerability described in CVE-2006-2062 represents a critical SQL injection flaw affecting Leadhound Full and LITE 2.1 versions, with potential impact on the Network Version "Full Version". This vulnerability stems from inadequate input validation and sanitization within multiple script files that process user-supplied data, creating pathways for malicious actors to inject arbitrary SQL commands into the backend database. The affected applications employ a common pattern where user inputs are directly concatenated into SQL queries without proper escaping or parameterization, fundamentally violating core database security principles.
The technical exploitation occurs through multiple entry points across various perl scripts within the Leadhound application suite. The primary attack vectors include the banner parameter in agent_links.pl, offset parameters in multiple scripts including agent_links.pl, agent_transactions.pl, agent_subaffiliates.pl, and agent_summary.pl, as well as camp_id parameters in agent_transactions_csv.pl, agent_subaffiliates.pl, and agent_camp_det.pl. Additionally, the login parameter in agent_commission_statement.pl, logged parameter in agent_commission_statement.pl and agent_camp_det.pl, agent_id parameter in agent_commission_statement.pl, and sub parameter in unspecified files all present potential injection points. These vulnerabilities collectively represent a comprehensive attack surface that allows remote code execution through database manipulation.
The operational impact of this vulnerability is severe and multifaceted, encompassing complete database compromise, data exfiltration, and potential system takeover. Attackers can leverage these injection points to bypass authentication mechanisms, retrieve sensitive user data including login credentials and financial information, modify or delete database records, and potentially escalate privileges to gain full administrative control over the application's database backend. The implications extend beyond immediate data theft to include potential service disruption and compliance violations, particularly given the nature of affiliate marketing data typically handled by such systems. This vulnerability directly aligns with CWE-89, which classifies SQL injection as a critical weakness in software design that allows attackers to manipulate database queries through untrusted input.
Mitigation strategies for this vulnerability require immediate implementation of proper input validation and parameterized queries across all affected scripts. The recommended approach involves adopting prepared statements or parameterized queries to ensure that user inputs are properly escaped and treated as data rather than executable code. Additionally, implementing proper input sanitization routines, enforcing least privilege database access, and conducting regular security code reviews can significantly reduce the attack surface. Organizations should also consider implementing web application firewalls and database activity monitoring to detect and prevent exploitation attempts. The remediation efforts should follow established security frameworks such as those outlined in the OWASP Top Ten and NIST guidelines for secure coding practices, ensuring that similar vulnerabilities are prevented in future development cycles. This vulnerability demonstrates the critical importance of input validation in preventing database injection attacks and highlights the need for comprehensive security testing throughout the software development lifecycle.
