CWE-22

A directory traversal vulnerability in the SevenZipFile.extractall() function of the python library py7zr v0.20.0 and earlier allows attackers to write arbitrary files via extracting a crafted 7z file.

A vulnerability classified as critical was found in scifio. Affected by this vulnerability is the function downloadAndUnpackResource of the file src/test/java/io/scif/util/DefaultSampleFilesService.java of the component ZIP File Handler. The manipulation leads to path traversal. The attack can be launched remotely. The name of the patch is fcb0dbca0ec72b22fe0c9ddc8abc9cb188a0ff31. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-215803.

A vulnerability, which was classified as critical, has been found in bspkrs MCPMappingViewer. Affected by this issue is the function extractZip of the file src/main/java/bspkrs/mmv/RemoteZipHandler.java of the component ZIP File Handler. The manipulation leads to path traversal. The attack may be launched remotely. The name of the patch is 6e602746c96b4756c271d080dae7d22ad804a1bd. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-215804.

Casdoor before v1.126.1 was discovered to contain an arbitrary file deletion vulnerability via the uploadFile function.

A directory traversal vulnerability in the ZIP archive extraction routines of KNIME Server since 4.3.0 can result in arbitrary files being overwritten on the server’s file system. This vulnerability is also known as ‘Zip-Slip’. An attacker can create a KNIME workflow that, when being uploaded, can overwrite arbitrary files that the operating system user running the KNIME Server process has write access to. The user must be authenticated and have permissions to upload files to KNIME Server. This can impact data integrity (file contents are changed) or cause errors in other software (vital files being corrupted). It can even lead to remote code execution if executable files are being replaced and subsequently executed by the KNIME Server process user. In all cases the attacker has to know the location of files on the server’s file system, though. Note that users that have permissions to upload workflows usually also have permissions to run them on the KNIME Server and can therefore already execute arbitrary code in the context of the KNIME Executor’s operating system user. There is no workaround to prevent this vulnerability from being exploited. Updates to fixed versions 4.13.6, 4.14.3, or 4.15.3 are advised.

A directory traversal vulnerability in the ZIP archive extraction routines of KNIME Analytics Platform 3.2.0 and above can result in arbitrary files being overwritten on the user’s system. This vulnerability is also known as ‘Zip-Slip’. An attacker can create a KNIME workflow that, when being opened by a user, can overwrite arbitrary files that the user has write access to. It’s not necessary to execute the workflow, opening the workflow is sufficient. The user will notice that something is wrong because an error is being reported but only after the files have already been written. This can impact data integrity (file contents are changed) or cause errors in other software (vital files being corrupted). It can even lead to remote code execution if executable files are being replaced and subsequently executed by the user. In all cases the attacker has to know the location of files on the user’s system, though.
