CVE-2007-4084 in Affiliate Network Pro
Summary
by MITRE
Multiple SQL injection vulnerabilities in AlstraSoft Affiliate Network Pro allow remote attackers to execute arbitrary SQL commands via (1) the pgmid parameter in an uploadProducts action to merchants/index.php and possibly (2) the rowid parameter to merchants/temp.php.

The vulnerability identified as CVE-2007-4084 represents a critical security flaw in AlstraSoft Affiliate Network Pro software that exposes multiple pathways for remote code execution through SQL injection attacks. This vulnerability resides within the web application's handling of user-supplied input parameters, specifically targeting the pgmid parameter in the uploadProducts action within merchants/index.php and potentially the rowid parameter in merchants/temp.php. The flaw allows malicious actors to inject arbitrary SQL commands directly into the database query execution flow, bypassing normal authentication and authorization mechanisms that should protect the application's backend systems.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the application's PHP scripts. When the pgmid parameter is processed in the uploadProducts action, the application fails to properly escape or validate user input before incorporating it into SQL queries. Similarly, the rowid parameter in the temp.php script exhibits the same deficiency, creating two distinct attack vectors for SQL injection exploitation. This weakness directly maps to CWE-89, which specifically addresses SQL injection vulnerabilities where untrusted data is used in SQL commands without proper sanitization or parameterization. The vulnerability exists because the application employs dynamic SQL construction techniques rather than prepared statements or parameterized queries, making it susceptible to manipulation through specially crafted input sequences.
The operational impact of CVE-2007-4084 is severe and multifaceted, potentially allowing attackers to gain complete control over the affected database and underlying system. Successful exploitation could enable unauthorized access to sensitive affiliate network data including merchant information, commission records, and potentially customer data. Attackers could execute destructive operations such as data deletion, modification, or unauthorized data exfiltration, while also gaining the ability to escalate privileges within the database environment. The vulnerability's remote nature means that attackers do not require physical access to the system or local network credentials to exploit it, making it particularly dangerous for web-facing applications. From an adversary perspective, this vulnerability aligns with ATT&CK technique T1190, which covers exploiting vulnerabilities in remote services, and T1071.004, covering application layer protocol manipulation through SQL injection attacks.
Mitigation strategies for CVE-2007-4084 should prioritize immediate implementation of input validation and parameterization techniques to prevent SQL injection exploitation. The most effective remediation involves replacing dynamic SQL query construction with prepared statements or parameterized queries that separate SQL code from user input data. Additionally, implementing proper input sanitization routines and employing web application firewalls can provide additional layers of protection against exploitation attempts. Organizations should also conduct comprehensive code reviews to identify and remediate similar vulnerabilities throughout the application codebase, as the presence of one SQL injection vulnerability often indicates potential for additional weaknesses. Regular security assessments and vulnerability scanning should be implemented to detect and address similar issues before they can be exploited by malicious actors. The remediation approach should follow security best practices established by OWASP and NIST guidelines for preventing SQL injection attacks, ensuring that all user-supplied data is properly validated and escaped before being incorporated into database queries.
