CVE-2021-3978 (GCVE-0-2021-3978)

Vulnerability from cvelistv5 – Published: 2025-01-29 10:00 – Updated: 2025-02-12 16:03

Summary

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.

Severity ?
