| Título | FOSSBilling >= 0.1.0, <= 0.8.6 Exposure of Access Control List Files to an Unauthorized Control |
|---|
| Descrição | A path-traversal flaw in the guest/system/template_exists API endpoint lets any unauthenticated attacker probe whether arbitrary files and directories exist anywhere on the server filesystem by submitting .. sequences in the file parameter; the boolean result is returned verbatim, breaking the intended restriction to the active theme directory. |
