Technical details
A path traversal vulnerability exists in the TAR.GZ extraction logic of XClarity Essentials OneCLI 5.5.0 that fails to properly validate file paths during archive extraction. An attacker can craft a malicious TAR.GZ update package with path traversal sequences (e.g., ../../../) to write arbitrary files with the process privileges when a user processes the package. This requires user interaction to open a specially crafted update package.
