Identifiers

GHSA-cqh2-vc2f-q4fh, CVE-2021-3907

Package Slug

go/github.com/cloudflare/cfrpki/cmd/octorpki

Vulnerability

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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.

Affected Versions

All versions before 1.4

Solution

Upgrade to version 1.4 or above.
