CVE-2006-6822 in eClassifieds
Summary
by MITRE
myprofile.asp in Enthrallweb eClassifieds does not properly validate the MM_recordId parameter during profile updates, which allows remote authenticated users to modify certain profile fields of another account by specifying that account s username in a modified MM_recordId parameter.

The vulnerability identified as CVE-2006-6822 resides within the myprofile.asp component of Enthrallweb eClassifieds, a web application designed for classified advertisements and user profile management. This issue represents a classic authorization bypass vulnerability that stems from inadequate input validation mechanisms within the application's profile update functionality. The flaw manifests when the application processes the MM_recordId parameter during profile modification operations, failing to properly verify whether the authenticated user has legitimate authorization to modify the specified target account.
The technical implementation of this vulnerability exploits a lack of proper access control checks within the application's backend processing logic. When a user attempts to update their profile, the system should validate that the requested modification targets the authenticated user's own account rather than arbitrary user accounts. However, the MM_recordId parameter is directly accepted and processed without sufficient validation, allowing malicious authenticated users to manipulate this parameter to reference another user's account identifier. This creates a privilege escalation scenario where users can modify profile information belonging to other accounts, potentially including sensitive data such as email addresses, contact information, or other personal details.
The operational impact of this vulnerability extends beyond simple data modification, as it fundamentally undermines the application's user authentication and authorization model. Attackers can leverage this flaw to impersonate other users, potentially gaining access to private communications, account recovery information, or other sensitive data associated with compromised accounts. This vulnerability particularly affects multi-user environments where users have varying levels of access privileges and where account isolation is critical for maintaining data integrity and user privacy. The risk is exacerbated by the fact that the vulnerability requires only authenticated access, meaning that any user with valid credentials can exploit this flaw to target other users within the system.
From a cybersecurity framework perspective, this vulnerability maps directly to CWE-285, which addresses improper authorization issues in software applications. The flaw also aligns with ATT&CK technique T1078.004, which covers valid accounts as a method for compromising systems through the exploitation of legitimate user credentials. Organizations should implement immediate mitigations including input validation for all user-supplied parameters, proper access control verification before processing profile modifications, and comprehensive audit logging of profile update activities. The recommended solution involves implementing strict parameter validation that ensures MM_recordId values match the authenticated user's own account identifier, along with mandatory authorization checks that verify user permissions before allowing any profile modification operations to proceed. Additionally, regular security assessments and code reviews should be conducted to identify and remediate similar authorization bypass vulnerabilities within the application's codebase.
