Kerentanan Improper Input Validation pada cloudflare octorpki, debian linux. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

OctoRPKI does not escape a URI with a filename containing "..", this allows a repository to create a file, (ex. rsync://example.org/repo/../../etc/cron.daily/evil.roa), which would then be written to disk outside the base cache folder. This could allow for remote code execution on the host machine OctoRPKI is running on.
