CWE
- CWE-379 - Creation of Temporary File in Directory with Insecure Permissions
Summary
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).

Mitigation
Phase: Requirements
Description:
- Many contemporary languages have functions which properly handle this condition. Older C temp file functions are especially susceptible.
Mitigation
Phase: Implementation
Description:
- Try to store sensitive tempfiles in a directory which is not world readable -- i.e., per-user directories.
Mitigation
Phase: Implementation
Description:
- Avoid using vulnerable temp file functions.
