    CVE-2021-3907

    Published: 11 Nov 2021Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
