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.
