CVE-2021-3907
Arbitrary filepath traversal via URI injection
Impact
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. ## Patches ## For more information If you have any questions or comments about this advisory email us at security@cloudflare.com
