The vulnerability identified as CVE-2005-4822 represents a critical SQL injection flaw within the Digger Solutions Intranet Open Source (IOS) version 2.7.2 web application. This vulnerability specifically affects the projects/project-edit.asp page, which serves as a management interface for project modifications within the intranet system. The flaw arises from insufficient input validation and sanitization of user-supplied data, creating an exploitable condition that enables malicious actors to manipulate the underlying database queries through crafted input parameters.
The technical implementation of this vulnerability stems from the improper handling of the project_id parameter within the ASP-based web application. When users interact with the project editing functionality, the application directly incorporates the project_id value into SQL query construction without adequate sanitization or parameterization. This design flaw aligns with CWE-89, which categorizes SQL injection vulnerabilities as a direct consequence of inadequate input validation and improper query construction. Attackers can exploit this weakness by crafting malicious project_id values that contain SQL command sequences, allowing them to bypass authentication mechanisms, extract sensitive data, modify database records, or even execute arbitrary system commands depending on the database backend and privilege levels.
The operational impact of this vulnerability extends beyond simple data compromise, as it fundamentally undermines the integrity and confidentiality of the entire intranet system. Remote attackers who successfully exploit this vulnerability can gain unauthorized access to sensitive project information, user credentials, and other confidential data stored within the database. The implications are particularly severe for enterprise environments where such intranet systems typically house proprietary business information, employee data, and strategic project details. The vulnerability's remote exploitability means that attackers do not require physical access to the network or system, making it a particularly dangerous threat vector that can be leveraged from anywhere on the internet.
Organizations utilizing Digger Solutions IOS version 2.7.2 must implement immediate mitigations to address this vulnerability. The primary remediation involves implementing proper input validation and parameterized queries throughout the application codebase, specifically targeting the project-edit.asp page and similar functionality. This approach aligns with ATT&CK technique T1190, which addresses the exploitation of vulnerabilities through SQL injection attacks. Security measures should include input sanitization at multiple layers, including application-level validation, database-level query parameterization, and proper error handling that does not expose database structure information to unauthorized users. Additionally, implementing web application firewalls and intrusion detection systems can provide additional protective layers against exploitation attempts. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities throughout the application's codebase, ensuring comprehensive protection against future SQL injection threats.
