Authenticated arbitrary file writes via history command
Published Mar 18, 2022 · Updated Aug 4, 2024
Path traversal in Brocade Fabric OS before 9.0.1a, 8.2.3, 8.2.0_CBN4, and 7.4.2h allows remote authenticated users to write files. The CLI history command accepts an attacker-controlled path and writes arbitrary content outside its intended file location. Access to an authenticated CLI session is required; successful exploitation alters files, with no reported confidentiality or availability impact.
