Rapid7 Velociraptor did not properly sanitize the client ID parameter to the CreateCollection API, allowing a directory traversal in where the collection task could be written. This issue affects ubi-reader before 0.8.5. By crafting a malicious UBIFS file with node names holding path traversal payloads (e.g././tmp/outside.txt), it's possible to force ubi_reader to write outside of the extraction directory. This is due to the fact that a node name (dent_node.name) is considered trusted and joined to the extraction directory path during processing, then the node content is written to that joined path. Ubireader_extract_files is vulnerable to path traversal when run against specifically crafted UBIFS files, allowing the attacker to overwrite files outside of the extraction directory (provided the process has write access to that file or directory). This issue affects yaffshiv up to version 0.1 included, which is the most recent at time of publication. By crafting a malicious YAFFS file, an attacker could force yaffshiv to write outside of the extraction directory. HL7 (Health Level 7) FHIR Core Libraries before 5.6.92 allow attackers to extract files into arbitrary directories via directory traversal from a crafted ZIP or TGZ archive (for a prepackaged terminology cache, NPM package, or comparison archive).Ī path traversal vulnerability affects yaffshiv YAFFS filesystem extractor.
