XWiki Platform may allow privilege escalation to programming rights via user's first name
Impact
Any user can edit his own profile and inject code which is going to be executed with programming right.
Steps to reproduce:
- Set your first name to
{{cache id="userProfile"}}{{groovy}}println("Hello from groovy!"){{/groovy}}{{/cache}}The first name appears as interpreted "Hello from groovy" instead of the expected fully escaped "{{cache id="userProfile"}}{{groovy}}println("Hello from groovy!"){{/groovy}}{{/cache}}".
The same vulnerability can also be exploited in all other places where short text properties are displayed, e.g., in apps created using Apps Within Minutes that use a short text field.
Patches
The problem has been patched on versions 13.10.9, 14.4.4, 14.7RC1.
Workarounds
There are no other workarounds than upgrading XWiki or patching the xwiki-commons-xml JAR file.
