CVE-2007-5402 in HelpBox
Summary
by MITRE
Multiple SQL injection vulnerabilities in Layton HelpBox 3.7.1 allow (1) remote attackers to execute arbitrary SQL commands via the sys_request_id parameter to editrequestenduser.asp; and allow remote authenticated users to execute arbitrary SQL commands via (2) the oldpassword parameter to writepwdenduser.asp, and the sys_request_id parameter to (3) changerequeststatus.asp, (4) editrequestuser.asp, (5) requestcommentsuser.asp, and (6) useractions.asp, different vectors than CVE-2004-2551.

The vulnerability identified as CVE-2007-5402 represents a critical SQL injection flaw affecting Layton HelpBox version 3.7.1, a web-based help desk application that facilitates customer support ticket management. This vulnerability stems from inadequate input validation and sanitization within multiple ASP pages that process user-supplied data without proper parameterization or escaping mechanisms. The flaw manifests across several attack vectors, making it particularly dangerous as it affects different functional areas of the application with varying levels of user authentication requirements.
The technical implementation of this vulnerability occurs through direct concatenation of user input into SQL query strings without proper sanitization or parameterized query construction. When the sys_request_id parameter is passed to editrequestenduser.asp, or when the oldpassword parameter is processed by writepwdenduser.asp, the application fails to validate or escape special characters that could alter the intended SQL command structure. This allows attackers to inject malicious SQL payloads that bypass authentication mechanisms and execute arbitrary database operations with the privileges of the web application's database user account.
The operational impact of CVE-2007-5402 extends beyond simple data theft, as authenticated users with minimal privileges can escalate their access to perform unauthorized database operations including data modification, deletion, or extraction. Remote attackers can exploit these vulnerabilities to gain complete control over the help desk database, potentially leading to information disclosure, data corruption, or service disruption. The presence of multiple attack vectors increases the exploitability surface, as different authentication levels and functional areas of the application are affected, including changerequeststatus.asp, editrequestuser.asp, requestcommentsuser.asp, and useractions.asp, each presenting unique opportunities for privilege escalation or data manipulation.
Security professionals should recognize this vulnerability as a classic example of CWE-89 SQL Injection, which is categorized under the OWASP Top Ten as a critical web application security risk. The attack patterns align with MITRE ATT&CK techniques for credential access and privilege escalation, specifically leveraging T1213 Credential Access and T1078 Valid Accounts to maintain persistent access. Organizations should implement immediate mitigations including input validation, parameterized queries, and least privilege database access controls. The vulnerability also demonstrates the importance of proper code review practices and input sanitization, as these flaws typically arise from insufficient security training and development practices that fail to incorporate secure coding principles into the application development lifecycle.
