Arbitrary file write via ZIP path traversal
Published Jul 20, 2021 · Updated Sep 26, 2024
Path traversal in Oracle Hyperion Infrastructure Technology 11.2.5.0 allows remote authenticated users to write arbitrary files. EPM Workspace Lifecycle Management extracts ZIP entries containing parent-directory segments without confining them to the restore directory. Exploitation requires high-privileged HTTP access and another user's interaction; escaped writes can overwrite sensitive files, execute code, or interrupt service.
