About CVE-2022-47412

CVE-2022-47412, an instance of CWE-79: Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’), was initially discovered by Rapid7 researcher Matthew Kienow in February 2023.

Generally speaking, it is a Multiple DMS XSS vulnerability that allows the intruder to retrieve information about the targeted user’s client. The intruder shares a malicious document that contains a cross-site scripting (XSS) code. When the document is saved within a document management system and the user performs a search action within document content in ONLYOFFICE Docs, the action triggers the execution of the XSS in the user’s browser.

Possible impact may be impersonation of a privileged user within organization’s portal by stealing the user’s session cookie or executing custom commands on behalf of the victim by hooking their browser.

The detailed scenario is described in the original report.
