CVE-2021-3978
Improper Preservation of Permissions in github.com/cloudflare/cfrpki/cmd/octorpki
Impact
### Impact When copying files with rsync, octorpki uses the "-a" flag 0, which forces rsync to copy binaries with the suid bit set as root. Since the provided service definition defaults to root (https://github.com/cloudflare/cfrpki/blob/master/package/octorpki.service) this could allow for a vector, when combined with another vulnerability that causes octorpki to process a malicious TAL file, for a local privilege escalation. ## For more information If you have any questions or comments about this advisory email us at security@cloudflare.com
