System-file disclosure via unfiltered video path
Published Apr 6, 2021 · Updated Sep 16, 2024
Path traversal in ASUS BMC firmware allows remote authenticated users with administrator access to read system files. The record-video function fails to filter special characters in a request parameter before using it as a file path, permitting traversal outside the intended directory. Exploitation requires BMC administrator privileges, and the published impact is limited to reading files.
