CVE-2021-3978

Published: Jan 29, 2025

Modified: Feb 12, 2025

PUBLISHED

CVSS v3.1

7.5

HIGH

Description

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.
