Detailsinfo

A vulnerability was found in deepin-clone up to 1.1.2 and classified as critical. Affected by this issue is the function Helper::getPartitionSizeInfo of the file /tmp/partclone.log of the component Log File Handler. The manipulation as part of a Symlink leads to a link following vulnerability. Using CWE to declare the problem leads to CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

deepin-clone before 1.1.3 uses a fixed path /tmp/partclone.log in the Helper::getPartitionSizeInfo() function to write a log file as root, and follows symlinks there. An unprivileged user can prepare a symlink attack there to create or overwrite files in arbitrary file system locations. The content is not attacker controlled.
