The vulnerability identified as CVE-2007-2591 represents a critical access control flaw within the Nokia Intellisync Mobile Suite versions 6.4.31.2, 6.6.0.107, and 6.6.2.2, with potential implications extending to Novell Groupwise Mobile Server and Nokia Intellisync Wireless Email Express implementations. This issue stems from insufficient input validation and authentication mechanisms within the user management interface, specifically in the usrMgr/userList.asp component that handles user account modifications. The vulnerability manifests when the system processes user identifiers through the userid parameter during update operations, creating an avenue for unauthorized modification of user account details and potential account deactivation.
The technical exploitation of this vulnerability occurs through manipulation of the userid parameter within the update action functionality, allowing remote attackers to bypass normal authentication and authorization checks. This flaw enables attackers to modify user account information including but not limited to user permissions, access rights, and account status. The vulnerability specifically targets the web-based administrative interface where user management operations are performed, making it particularly dangerous as it can be exploited over network connections without requiring local system access. The implementation lacks proper parameter sanitization and validation, allowing malicious input to directly influence the database operations performed by the application.
The operational impact of this vulnerability extends beyond simple unauthorized access to account modification capabilities, potentially leading to complete account deactivation and service disruption. Attackers can exploit this weakness to disable legitimate user accounts, effectively performing denial of service attacks against targeted users while simultaneously gaining unauthorized access to modify critical user information. The vulnerability affects organizations relying on mobile email and collaboration services where user account management is critical for maintaining business continuity and security. Organizations may experience service degradation, unauthorized data modification, and potential compromise of sensitive user information, particularly in environments where mobile email services are extensively utilized.
Mitigation strategies should focus on implementing comprehensive input validation and parameter sanitization within the affected applications, ensuring that all user identifiers passed through the userid parameter are properly authenticated and authorized before any account modifications occur. System administrators should immediately apply vendor patches and updates to address this vulnerability, while also implementing network segmentation and access controls to limit exposure of the vulnerable components. The vulnerability aligns with CWE-20, representing a weakness in input validation, and maps to ATT&CK technique T1078 for valid accounts and T1485 for data destruction, highlighting the multi-faceted nature of the threat. Organizations should also consider implementing additional monitoring and logging mechanisms to detect unauthorized account modification attempts and establish incident response procedures to address potential exploitation of this vulnerability.
