CVE-2021-3978
Last modified
CVE-2021-3978 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
