Arbitrary file writes via unchecked archive paths
Published Jan 31, 2024 · Updated Aug 23, 2024
Path traversal in Anchore Stereoscope before 0.0.1 allows local users to write files outside its temporary extraction directory. UntarToDirectory joined the destination with an untrusted tar header name, then created directories or opened files without checking that the resulting path remained beneath the destination. Exploitation requires a crafted OCI tar archive to be supplied to a consuming application, and file-write effects are bounded by that process's filesystem permissions.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
