CVE-2023-0591

5.5 · MEDIUM
Published Jan 31, 2023 ubi_reader_project CWE-22 EPSS 0.39% (32th pctl)

Overview

CVE-2023-0591 is a medium-severity vulnerability affecting ubi_reader_project ubi_reader. It was published on January 31, 2023 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical Description

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 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. 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 issue affects ubi-reader before 0.8.5.

Remediation

Check the references section for vendor advisories and patches from ubi_reader_project. Update ubi_reader to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
