+ <h3>CVE-2020-11651 - Authentication bypass vulnerabilities</h3>
+ <p>The ClearFuncs class processes unauthenticated requests and
+ unintentionally exposes the _send_pub() method, which can be used to
+ queue messages directly on the master publish server. Such messages
+ can be used to trigger minions to run arbitrary commands as root.</p>
+ <p>The ClearFuncs class also exposes the method _prep_auth_info(),
+ which returns the "root key" used to authenticate commands from the
+ local root user on the master server. This "root key" can then be
+ used to remotely call administrative commands on the master server.
+ This unintentional exposure provides a remote un-authenticated
+ attacker with root-equivalent access to the salt master.</p>
+ <p/>
+ <h3>CVE-2020-11652 - Directory traversal vulnerabilities</h3>
+ <p>The wheel module contains commands used to read and write files
+ under specific directory paths. The inputs to these functions are
+ concatenated with the target directory and the resulting path is not
+ canonicalized, leading to an escape of the intended path restriction.</p>
+ <p>The get_token() method of the salt.tokens.localfs class (which is
+ exposed to unauthenticated requests by the ClearFuncs class) fails
+ to sanitize the token input parameter which is then used as a
+ filename, allowing insertion of ".." path elements and thus reading
+ of files outside of the intended directory. The only restriction is
+ that the file has to be deserializable by salt.payload.Serial.loads().</p>
