CVE-2023-6367 in WhatsUp Gold
Summary
by MITRE • 12/14/2023
In WhatsUp Gold versions released before 2023.1, a stored cross-site scripting (XSS) vulnerability has been identified. It is possible for an attacker to craft a XSS payload and store that value within Roles.
If a WhatsUp Gold user interacts with the crafted payload, the attacker would be able to execute malicious JavaScript within the context of the victims browser.

The vulnerability identified in CVE-2023-6367 represents a critical stored cross-site scripting flaw within WhatsUp Gold software versions prior to 2023.1. This type of vulnerability falls under the Common Weakness Enumeration category CWE-79 which specifically addresses cross-site scripting conditions where untrusted data is improperly integrated into web pages without proper validation or encoding. The flaw exists within the application's handling of user input within the Roles functionality, creating an environment where malicious actors can inject persistent malicious code that remains stored within the application's database or configuration system.
The technical execution of this vulnerability requires an attacker to craft a malicious cross-site scripting payload and successfully store it within the Roles component of the WhatsUp Gold application. This stored payload becomes persistent and remains available for execution whenever a legitimate user interacts with the affected system. The vulnerability is classified as stored XSS because the malicious script is not executed immediately upon input but rather waits for a victim user to perform an action that triggers the payload execution within their browser context. This timing aspect makes the vulnerability particularly dangerous as it can remain dormant for extended periods before being activated by unsuspecting users.
The operational impact of CVE-2023-6367 extends beyond simple script execution, as it provides attackers with the ability to operate within the victim user's browser session with the same privileges and permissions as that user. This capability enables attackers to perform actions such as stealing session cookies, accessing sensitive data, modifying user permissions, or even executing further malicious activities through the compromised user's authenticated session. The vulnerability specifically targets the Roles functionality, suggesting that attackers could potentially escalate privileges or gain access to administrative controls if the affected roles contain elevated permissions. According to the MITRE ATT&CK framework, this vulnerability maps to techniques involving client-side attacks and session hijacking, with potential lateral movement capabilities when users with elevated privileges interact with the malicious content.
The security implications of this stored XSS vulnerability are significant for organizations relying on WhatsUp Gold for network monitoring and management. Attackers exploiting this flaw could gain unauthorized access to network configurations, device credentials, and monitoring data that would otherwise be protected by proper access controls. The persistent nature of stored XSS makes it particularly challenging to detect and remediate, as the malicious payload can remain undetected for extended periods while continuing to compromise user sessions. Organizations should prioritize immediate remediation through the application of the vendor-provided security patch for version 2023.1 or later, while also implementing network monitoring to detect potential exploitation attempts. Additionally, security teams should consider conducting thorough vulnerability assessments of related systems and implementing proper input validation controls to prevent similar issues in other applications within their environment.
