What it is

AIL Project contains a stored cross-site scripting vulnerability in the translation controls displayed for chat messages and forum posts.

The affected templates inserted message and post identifiers directly into inline JavaScript onclick handlers:

onclick="translateMessageToPreferredLanguage('{{ message['id'] }}', '{{ mess_id_escape }}', this)"

and:

onclick="translatePostToPreferredLanguage('{{ post['id'] }}', '{{ post_id_escape }}', this)"

These values were HTML-template escaped but were not safely encoded for use as JavaScript string literals inside an HTML attribute. A specially crafted identifier containing quotation marks, escape characters, or other JavaScript syntax could therefore terminate the expected string argument and inject arbitrary JavaScript into the event handler.

Because the affected values are associated with indexed chat messages or forum posts, a malicious value may remain stored by AIL and be rendered whenever an analyst accesses the corresponding chat or forum explorer view.

Successful exploitation requires the victim to click the affected Translate to preferred language button. The injected code would then execute in the victim’s browser under the security origin of the AIL instance.
