Senserva AI Opinion for CVE-2022-30333
RARLAB's UnRAR utility on Linux and UNIX follows crafted paths during extraction, letting an attacker write files outside the extraction directory. The 99 percent EPSS score and confirmed ransomware use trace to its exploitation against servers that automatically unpack RAR attachments, notably mail platforms, where one emailed archive becomes file-write and then code execution. CISA listed it in August 2022.
Do this: Update unrar on all Linux and UNIX systems and identify any service that auto-extracts untrusted archives.
