In Mitre's CVE dictionary: CVE-2020-24379, CVE-2020-24916.
More information:

Two vulnerabilities were discovered in yaws, a high performance HTTP 1.1 webserver written in Erlang.

  • CVE-2020-24379

    The WebDAV implementation is prone to a XML External Entity (XXE) injection vulnerability.

  • CVE-2020-24916

    The CGI implementation does not properly sanitize CGI requests allowing a remote attacker to execute arbitrary shell commands via specially crafted CGI executable names.

For the stable distribution (buster), these problems have been fixed in version 2.0.6+dfsg-1+deb10u1.

We recommend that you upgrade your yaws packages.
