CVE-2007-0350 in FileMailer
Summary
by MITRE
Multiple SQL injection vulnerabilities in (a) index.php and (b) dl.php in SmE FileMailer 1.21 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) ps, (2) us, (3) f, or (4) code parameter. NOTE: the us vector in index.php is already covered by CVE-2007-0346.

The vulnerability identified as CVE-2007-0350 represents a critical SQL injection flaw affecting SmE FileMailer version 1.21 and earlier. This vulnerability resides in two primary script files: index.php and dl.php, making it particularly dangerous as it affects multiple entry points within the application. The vulnerability stems from insufficient input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into SQL database queries. Attackers can exploit this weakness by manipulating specific parameters to inject malicious SQL commands that bypass authentication mechanisms and gain unauthorized access to the underlying database.
The technical exploitation occurs through four distinct parameter vectors: ps, us, f, and code, all of which are susceptible to SQL injection attacks. The ps parameter in index.php and the f and code parameters in dl.php provide attack surfaces where malicious input can be directly incorporated into database queries without proper sanitization. The us parameter in index.php, while also vulnerable, has been previously documented under CVE-2007-0346, indicating this represents a known weakness that was not adequately addressed in the affected version. This vulnerability directly maps to CWE-89, which specifically addresses SQL injection weaknesses in software applications, and aligns with ATT&CK technique T1190 for exploitation of vulnerabilities in web applications.
The operational impact of this vulnerability is severe and multifaceted, potentially allowing remote attackers to execute arbitrary SQL commands against the database system. Successful exploitation could result in complete database compromise, including unauthorized data access, data modification, or even data deletion. Attackers might leverage this vulnerability to bypass authentication mechanisms, escalate privileges, or extract sensitive information from the database. The vulnerability's remote nature means that attackers do not require physical access to the system, making it particularly dangerous for web applications that are publicly accessible. This type of vulnerability can lead to data breaches, system compromise, and potential lateral movement within network environments where the affected application operates.
Mitigation strategies for this vulnerability require immediate attention and comprehensive implementation. The primary remediation involves implementing proper input validation and parameterized queries throughout the affected application code. All user-supplied inputs must be rigorously validated and sanitized before being incorporated into database queries. The application should utilize prepared statements or parameterized queries to ensure that user input cannot alter the intended structure of SQL commands. Additionally, implementing proper access controls and least privilege principles can help limit the potential damage from successful exploitation. Regular security audits and code reviews should be conducted to identify similar vulnerabilities in other parts of the application. Organizations should also consider implementing web application firewalls and intrusion detection systems to monitor for exploitation attempts. The vulnerability underscores the importance of following secure coding practices and adhering to OWASP Top Ten security guidelines to prevent similar issues in future development cycles.
