qtnx 0.9 stores non-custom SSH keys in a world-readable configuration file. If a user has a world-readable or world-executable home directory, another local system user could obtain the private key used to connect to remote NX sessions.

Weakness

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Affected Software

Name Vendor Start Version End Version
Qtnx Qtnx_project 0.9 0.9

Extended Description

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
