Name of the Vulnerable Software and Affected Versions insights-client (affected versions not specified)

Description A security issue occurs due to insecure file operations or unsafe handling of temporary files and directories, leading to local privilege escalation. An unprivileged local user or attacker could create the /var/tmp/insights-client directory with read, write, and execute permissions before the insights-client is registered by root. After registration, an attacker could control the directory content by putting malicious scripts into it and executing arbitrary code as root, bypassing SELinux protections.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
