CVE-2023-28465: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

December 12, 2023 (updated December 15, 2023)

The package-decompression feature in HL7 (Health Level 7) FHIR Core Libraries before 5.6.106 allows attackers to copy arbitrary files to certain directories via directory traversal, if an allowed directory name is a substring of the directory name chosen by the attacker. NOTE: this issue exists because of an incomplete fix for CVE-2023-24057.
