CVE-2008-4606 in IP Reg
Summary
by MITRE
Multiple SQL injection vulnerabilities in IP Reg 0.4 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) location_id parameter to locationdel.php and (2) vlan_id parameter to vlanedit.php. NOTE: the vlanview.php and vlandel.php vectors are already covered by CVE-2007-6579.

The vulnerability identified as CVE-2008-4606 represents a critical SQL injection flaw affecting IP Reg version 0.4 and earlier installations. This vulnerability resides within the web application's input validation mechanisms, specifically targeting two distinct script files that handle network infrastructure management operations. The affected components include locationdel.php which processes location_id parameters and vlanedit.php which handles vlan_id parameters, both of which fail to properly sanitize user-supplied input before incorporating it into database queries.
The technical exploitation of this vulnerability occurs through improper input validation and sanitization practices that allow malicious actors to inject arbitrary SQL commands into the database layer. When an attacker submits specially crafted input through the location_id parameter in locationdel.php or the vlan_id parameter in vlanedit.php, the application fails to escape or filter these inputs appropriately. This creates an opportunity for attackers to manipulate the underlying database queries, potentially gaining unauthorized access to sensitive network configuration data, modifying existing records, or even executing destructive operations on the database system itself.
From an operational impact perspective, this vulnerability poses significant risks to network infrastructure management systems that rely on IP Reg for tracking and managing network resources. The exploitation of these SQL injection flaws could lead to complete compromise of the network inventory database, exposing sensitive information about network topology, IP address allocations, and VLAN configurations. Attackers could leverage this vulnerability to escalate privileges, access confidential network data, or disrupt network management operations. The vulnerability affects organizations that maintain network infrastructure documentation and configuration management systems, making it particularly dangerous for enterprises with complex network environments.
The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications. This classification indicates that the flaw represents a fundamental failure in input validation and query construction practices within the application's database interaction layer. The ATT&CK framework categorizes this as a Database Injection technique under the broader category of Command and Control activities, where adversaries exploit application vulnerabilities to manipulate backend databases. Organizations should implement proper parameterized queries, input validation, and output encoding to prevent such injection attacks. The vulnerability also demonstrates the importance of regular security assessments and patch management processes, as the affected version (0.4 and earlier) represents an outdated release that lacks modern security protections.
Mitigation strategies should focus on immediate patching of the affected IP Reg application to version 0.5 or later, which contains the necessary security fixes. Additionally, organizations should implement web application firewalls to monitor and filter suspicious SQL injection attempts, enforce strict input validation at all application entry points, and conduct regular security code reviews to identify similar vulnerabilities in other components. Network segmentation and least privilege access controls should be implemented to limit the potential impact of successful exploitation, while database access should be restricted to only necessary application functions. Regular security training for developers on secure coding practices and input validation techniques remains essential for preventing similar vulnerabilities in future development cycles.
