Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-79

Untrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

Recommended fix High confidence
  1. 1. Navigate to the daloRADIUS source code repository at https://github.com/lirantal/daloradius
  2. 2. Locate the file mng-del.php in the repository
  3. 3. Apply the changes from commit ec3b4a419e20540cf28ce60e48998b893e3f1dea to mng-del.php, specifically addressing the unescaped variable on line 116 that is reflected in the DOM
  4. 4. Verify that the variable(s) are now properly escaped before being reflected in the HTML/DOM
  5. 5. For additional CSRF mitigation as mentioned in the advisory, ensure the session cookie includes SameSite=Lax or implement CSRF tokens in all forms
  6. 6. Consider implementing a Content-Security-Policy header to provide defense-in-depth against XSS attacks
  7. 7. Test the mng-del.php functionality after applying the patch to ensure legitimate operations still work
