daloRADIUS is an open source RADIUS web management application. daloRadius 1.3 and prior are vulnerable to a combination cross site scripting (XSS) and cross site request forgery (CSRF) vulnerability which leads to account takeover in the mng-del.php file because of an unescaped variable reflected in the DOM on line 116. This issue has been addressed in commit ec3b4a419e. Users are advised to manually apply the commit in order to mitigate this issue. Users may also mitigate this issue with in two parts 1) The CSRF vulnerability can be mitigated by making the daloRadius session cookie to samesite=Lax or by the implimentation of a CSRF token in all forms. 2) The XSS vulnerability may be mitigated by escaping it or by introducing a Content-Security policy.
Weakness
The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request.

Potential Mitigations
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, use anti-CSRF packages such as the OWASP CSRFGuard. [REF-330]
- Another example is the ESAPI Session Management control, which includes a component for CSRF. [REF-45]
- Use the “double-submitted cookie” method as described by Felten and Zeller:
- When a user visits a site, the site should generate a pseudorandom value and set it as a cookie on the user’s machine. The site should require every form submission to include this value as a form value and also as a cookie value. When a POST request is sent to the site, the request should only be considered valid if the form value and the cookie value are the same.
- Because of the same-origin policy, an attacker cannot read or modify the value stored in the cookie. To successfully submit a form on behalf of the user, the attacker would have to correctly guess the pseudorandom value. If the pseudorandom value is cryptographically strong, this will be prohibitively difficult.
- This technique requires Javascript, so it may not work for browsers that have Javascript disabled. [REF-331]
