The vulnerability identified as CVE-2006-5987 represents a critical sql injection flaw within the aspintranet application, specifically affecting the default.asp component. This weakness resides in the application's handling of user input through the 'a' parameter, which serves as an entry point for malicious actors to manipulate database queries. The vulnerability affects versions including but not limited to 1.2, indicating it was present in a widely distributed web application framework that provided intranet functionality to organizations. The flaw stems from insufficient input validation and sanitization mechanisms within the application's backend processing logic, creating an avenue for attackers to inject malicious sql code that bypasses normal authentication and authorization controls.
The technical exploitation of this vulnerability occurs when an attacker submits carefully crafted input through the 'a' parameter in the default.asp script. This input is then directly incorporated into sql queries without proper sanitization or parameterization, allowing the attacker to manipulate the intended query execution flow. The vulnerability aligns with CWE-89 which classifies sql injection as a weakness where untrusted data is used in sql commands without proper validation or escaping. Attackers can leverage this flaw to execute unauthorized database operations including but not limited to data extraction, modification, deletion, or even privilege escalation within the database environment. The impact extends beyond simple data theft as attackers may gain persistent access to underlying database systems, potentially leading to complete system compromise.
Operationally, this vulnerability poses significant risks to organizations utilizing aspintranet for internal web applications. The remote nature of the attack means that threat actors can exploit the flaw from outside the network perimeter without requiring local system access or credentials. This characteristic places the vulnerability in the ATT&CK framework under initial access techniques, specifically leveraging vulnerabilities in web applications to gain unauthorized access to systems. Organizations may experience data breaches, unauthorized modifications to critical business information, and potential service disruptions. The vulnerability's presence in default.asp suggests it affects core application functionality, potentially impacting multiple organizational departments that rely on the intranet platform for business operations.
Mitigation strategies for CVE-2006-5987 should prioritize immediate patching of affected systems with vendor-provided security updates or application upgrades that address the input validation weaknesses. Organizations must implement proper input sanitization techniques including parameterized queries, stored procedures, and strict input validation routines that filter or escape special characters commonly used in sql injection attacks. Network segmentation and web application firewalls can provide additional layers of protection by monitoring and filtering suspicious traffic patterns targeting the vulnerable parameter. Security monitoring should include detection of unusual sql query patterns and unauthorized database access attempts. Regular security assessments and penetration testing should verify that input validation mechanisms are properly implemented and functioning. The vulnerability demonstrates the critical importance of secure coding practices and input validation as outlined in industry standards such as the owasp top ten and iso 27001 security controls. Organizations should also consider implementing database activity monitoring solutions to detect and respond to potential exploitation attempts.
