A TarSlip vulnerability exists in the deepjavalibrary/djl, affecting version 0.26.0 and fixed in version 0.27.0. This vulnerability allows an attacker to manipulate file paths within tar archives to overwrite arbitrary files on the target system. Exploitation of this vulnerability could lead to remote code execution, privilege escalation, data theft or manipulation, and denial of service. The vulnerability is due to improper validation of file paths during the extraction of tar files, as demonstrated in multiple occurrences within the library's codebase, including but not limited to the files_util.py and extract_imagenet.py scripts.
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '\..\filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
