Detailsinfo

A vulnerability, which was classified as critical, was found in OpenText Flipper 3.1.2. This affects some unknown processing of the component Backend API. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. CWE is classifying the issue as CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Insufficient Granularity of Access Control vulnerability in opentext Flipper allows Exploiting Incorrectly Configured Access Control Security Levels. The vulnerability could allow a low privilege user to interact with the backend API without sufficient privileges. This issue affects Flipper: 3.1.2.
