The vulnerability identified as CVE-2016-15002 represents a critical privilege escalation flaw within MONyog Ultimate version 6.63, specifically within the Cookie Handler component. This security weakness stems from improper validation of the HasServerEdit and IsAdmin arguments, which are critical parameters used to determine user permissions and access levels within the application's authentication and authorization framework. The vulnerability's classification as critical indicates the potential for severe impact on system security and data integrity.
The technical flaw manifests through the insecure handling of cookie-based authentication parameters that control administrative privileges. When the HasServerEdit or IsAdmin arguments are manipulated, attackers can bypass normal access controls and elevate their privileges within the MONyog Ultimate application. This occurs because the application fails to properly validate or sanitize these cookie values before processing them, allowing malicious actors to inject arbitrary privilege levels into their authenticated sessions. The vulnerability operates at the application logic level, specifically within the authentication subsystem where session management and access control decisions are made.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it enables remote attackers to gain administrative access to the MONyog Ultimate monitoring system. This represents a significant security risk since MONyog Ultimate is typically used for database monitoring and management, making the compromised system a potential gateway for broader network infiltration. Attackers can exploit this vulnerability without requiring local access or credentials, leveraging the remote attack vector to manipulate session cookies and assume elevated privileges. The implications include potential data exfiltration, system compromise, and unauthorized database access that could affect entire database infrastructures.
The vulnerability aligns with CWE-285, which addresses improper authorization issues, and demonstrates characteristics consistent with ATT&CK technique T1078 for Valid Accounts and T1484 for Domain Controller Implantation. Organizations using MONyog Ultimate should immediately implement mitigations including patching to the latest version, implementing strict cookie validation mechanisms, and monitoring for suspicious authentication patterns. Additional security measures should include network segmentation, enhanced logging of authentication events, and regular security assessments of web application components. The remote exploitability of this vulnerability necessitates immediate action to prevent potential compromise of database monitoring systems and the sensitive information they handle.
