CVE-2017-16544 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks.. EPSS estimates a 6.24% chance of exploitation in the next 30 days.
