| Название | CodeLibs Fess 15.5.1 Arbitrary File Write |
|---|
| Описание | The update() method in AdminDesignAction writes user-supplied content directly to a JSP file on disk after passing it through decodeJsp(). The filter only escapes <% %> scriptlet tags and <%= %> expression tags — JSP EL expressions (${}) are not touched at all. An attacker with the admin-design role can inject JSP EL expressions into content. EL expressions are evaluated by the JSP/Servlet container at render time and can invoke arbitrary Java methods, achieving Remote Code Execution. |
