Technical ContextAI · show details

This vulnerability is classified as Incorrect Authorization (CWE-863), which allows attackers to bypass authorization checks to access restricted resources. An access control vulnerability was discovered in the Reports section due to a specific access restriction not being properly enforced for users with limited privileges. If a logged-in user with reporting privileges learns how to create a specific application request, they might be able to make limited changes to the reporting configuration. This could result in a partial loss of data integrity. In Guardian/CMC instances with a reporting configuration, there could be limited Denial of Service (DoS) impacts, as the reports may not reach their intended destination, and there could also be limited information disclosure impacts. Furthermore, modifying the destination SMTP server for the reports could lead to the compromise of external credentials, as they might be sent to an unauthorized server. This could expand the scope of the attack. Affected products include: Nozominetworks Cmc, Nozominetworks Guardian.

Attack Technique

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
