go-tuf is a Go implementation of The Update Framework (TUF). go-tuf's TAP 4 Multirepo Client uses the map file repository name string (repoName) as a filesystem path component when selecting the local metadata cache directory. Starting in version 2.0.0 and prior to version 2.4.1, if an application accepts a map file from an untrusted source, an attacker can supply a repoName containing traversal (e.g., ../escaped-repo) and cause go-tuf to create directories and write the root metadata file outside the intended LocalMetadataDir cache base, within the running process's filesystem permissions. Version 2.4.1 contains a patch.
AnalysisAI
Path traversal in go-tuf versions 2.0.0 through 2.4.0 allows local attackers with low privileges to write metadata files outside the intended cache directory by injecting directory traversal sequences into the repository name parameter. An attacker supplying a malicious map file can escape the LocalMetadataDir boundary and create directories within the process's filesystem permissions. …
