CVE-2007-1925 in Nukeet
Summary
by MITRE
The borrado function in modules/Your_Account/index.php in Tru-Zone Nuke ET 3.4 before fix 7 does not verify that account deletion requests come from the account owner, which allows remote authenticated users to delete arbitrary accounts via a modified cookie.

The vulnerability identified as CVE-2007-1925 resides within the Tru-Zone Nuke ET 3.4 content management system, specifically in the borrado function located in modules/Your_Account/index.php. This flaw represents a critical authorization bypass issue that undermines the fundamental security controls designed to protect user accounts. The vulnerability stems from insufficient input validation and authentication checks within the account deletion mechanism, creating a pathway for malicious actors to exploit the system's trust model. The affected version lacks proper verification procedures that should confirm the identity of users attempting account deletion operations, thereby exposing the entire user base to potential compromise.
The technical implementation of this vulnerability manifests through the improper handling of authentication tokens within the cookie-based session management system. When a user attempts to delete their account, the system should validate that the deletion request originates from the legitimate account owner by cross-referencing the session cookie with the target account's ownership information. However, the borrado function fails to perform this critical validation step, allowing any authenticated user to submit a modified cookie containing arbitrary account identifiers. This weakness directly maps to CWE-285, which addresses improper authorization within authentication mechanisms, and specifically relates to the lack of proper access control checks. The vulnerability operates at the application layer and requires minimal privileges to exploit, as the attacker only needs an existing valid account within the system.
The operational impact of this vulnerability extends far beyond simple account deletion, as it enables unauthorized account manipulation that can lead to broader system compromise. An attacker with a valid account can leverage this flaw to systematically target other users' accounts, potentially leading to data breaches, identity theft, or service disruption. The implications are particularly severe given that the vulnerability affects the core user management functionality of the CMS, which forms the foundation of user authentication and authorization within the system. This flaw creates a persistent threat vector that can be exploited repeatedly, as long as the attacker maintains access to a valid account. The vulnerability also aligns with ATT&CK technique T1531, which covers "Account Access Removal", and demonstrates how insufficient access control can enable lateral movement and account takeover scenarios within web applications.
Mitigation strategies for CVE-2007-1925 must address both the immediate technical flaw and implement broader security controls to prevent similar issues. The primary remediation involves implementing robust authentication checks within the borrado function to verify that deletion requests originate from the legitimate account owner. This requires strengthening the session validation process to ensure that cookies contain proper ownership verification tokens before executing deletion operations. Organizations should also implement comprehensive input sanitization and parameter validation to prevent cookie manipulation attacks. The fix should include cryptographic verification of account ownership through server-side session management, ensuring that account identifiers cannot be modified without proper authorization. Additionally, implementing proper logging and monitoring of account deletion activities will help detect and respond to unauthorized attempts. Security best practices recommend following the principle of least privilege and implementing multi-factor authentication for sensitive operations to further reduce the attack surface. The vulnerability highlights the critical importance of validating user intent and ownership verification in all administrative functions, particularly those involving account lifecycle management, as outlined in industry standards such as OWASP Top Ten and NIST cybersecurity frameworks.
