Title
BleachBit: Exploit File Delete to Escalate Privilege
Summary
BleachBit cleans files to free disk space and to maintain privacy. Prior to 6.0.1, privileged Windows cleaning does not lock and validate a target's parent directory before deletion. A local unprivileged user can replace that directory with a Windows junction and use a native symlink to redirect the elevated deletion to an attacker-selected file. The arbitrary privileged file deletion can be combined with Windows Installer behavior to obtain local SYSTEM privileges. This issue is fixed in version 6.0.1.
