      <title>CVE-2021-3978 — Improper Preservation of Permissions in github.com/cloudflare/cfrpki/cmd/octorpki</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2021-3978</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Cloudflare octorpki&lt;/p&gt;
&lt;p&gt;When copying files with rsync, octorpki uses the &amp;#34;-a&amp;#34; 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.&lt;/p&gt;</description>
