Official description
NT OneAPP developed by NewType Infortech has an Improper Certificate Validation vulnerability. Unauthenticated network-adjacent attackers can perform a man-in-the-middle attack by failing to validate the server certificate and the hostname, thereby intercepting or modifying communications between the application and the server.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
