CVE-2007-1122 in Address Book Continued
Summary
by MITRE
Multiple SQL injection vulnerabilities in Mathis Dirksen-Thedens ZephyrSoft Toolbox Address Book Continued (ABC) 1.00 and 1.01 allow remote attackers to execute arbitrary SQL commands via the id parameter to the (1) updateRow and (2) deleteRow functions in functions.php, a variant of a SQL injection issue that was fixed in 1.01. NOTE: some of these details are obtained from third party information.

The CVE-2007-1122 vulnerability represents a critical SQL injection flaw in the ZephyrSoft Toolbox Address Book Continued (ABC) version 1.00 and 1.01, demonstrating a fundamental security weakness in web application input validation. This vulnerability specifically affects the updateRow and deleteRow functions within the functions.php file, where the id parameter is directly incorporated into SQL queries without proper sanitization or parameterization. The flaw allows remote attackers to manipulate database operations by injecting malicious SQL code through the id parameter, potentially enabling unauthorized data access, modification, or deletion. The vulnerability exists in both versions 1.00 and 1.01, though version 1.01 contains a variant of the fix for the same SQL injection issue, suggesting that the developers were aware of the problem but failed to implement complete protection mechanisms. This type of vulnerability falls under CWE-89, which specifically addresses SQL injection weaknesses in software applications, and aligns with ATT&CK technique T1190 for exploiting SQL injection vulnerabilities to gain unauthorized access to database systems.
The technical exploitation of this vulnerability occurs when an attacker submits malicious input through the id parameter in the updateRow or deleteRow functions, causing the application to execute unintended SQL commands. The lack of input validation means that attackers can append SQL commands to the id parameter, potentially bypassing authentication mechanisms or gaining access to sensitive data stored in the backend database. The vulnerability is particularly dangerous because it affects core database operations, allowing attackers to perform full read and write operations on the address book database. Attackers could potentially extract confidential information such as user credentials, personal contact details, or other sensitive data stored within the application's database structure. The persistence of this vulnerability across both versions indicates inadequate security testing or oversight during the development lifecycle, particularly in input handling and database query construction processes.
The operational impact of CVE-2007-1122 extends beyond simple data exposure, potentially enabling complete system compromise through database manipulation. Remote attackers could leverage this vulnerability to perform unauthorized data modification, delete critical records, or even escalate privileges within the database environment. The vulnerability's presence in both versions suggests a lack of proper security controls in the application architecture, particularly around parameter handling in database queries. Organizations using these versions face significant risk of data breaches, regulatory compliance violations, and potential legal consequences due to unauthorized access to sensitive personal information. The vulnerability also demonstrates poor security hygiene in software development practices, as proper input validation and parameterized queries should have been implemented to prevent such issues. This type of vulnerability commonly leads to cascading security problems, as attackers can use the initial compromise to gain deeper access to network resources or launch further attacks against connected systems.
Mitigation strategies for CVE-2007-1122 require immediate implementation of proper input validation and parameterized queries to prevent SQL injection exploitation. Organizations should upgrade to patched versions of the ZephyrSoft Toolbox Address Book Continued application, as version 1.01 contains a variant of the fix for similar issues, though it's crucial to verify that the specific vulnerability has been fully addressed. The recommended approach involves implementing proper input sanitization techniques, using prepared statements or parameterized queries, and ensuring that all database interactions validate and sanitize user inputs before processing. Additionally, network segmentation and access controls should be implemented to limit exposure of vulnerable applications to untrusted networks. Security monitoring should be enhanced to detect anomalous database access patterns that might indicate exploitation attempts, and regular security assessments should be conducted to identify similar vulnerabilities in other applications. Organizations should also consider implementing web application firewalls and intrusion detection systems to provide additional layers of protection against SQL injection attacks and other common web application vulnerabilities.
