Arbitrary file read via improperly authorized CLI commands
Published May 6, 2021 · Updated Nov 8, 2024
Information disclosure in Cisco WAAS 6.4.5a and earlier allows local users to read arbitrary files through the CLI. The CLI improperly validates input and authorizes a specific command sequence, allowing files outside the account's permissions to be read. Authenticated local CLI access is required; successful exploitation exposes file contents without granting write access or disrupting service.
