CVE-2021-3907

Arbitrary filepath traversal via URI injection

State: Published
Severity: 7.4 High
Published: Nov 11, 2021
Updated: Sep 17, 2024
Reserved: Oct 26, 2021

Description

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.
