CVE-2019-16216 (GCVE-0-2019-16216)

Vulnerability from cvelistv5 – Published: 2019-09-18 11:08 – Updated: 2024-08-05 01:10
VLAI
Summary
Zulip server before 2.0.5 incompletely validated the MIME types of uploaded files. A user who is logged into the server could upload files of certain types to mount a stored cross-site scripting attack on other logged-in users. On a Zulip server using the default local uploads backend, the attack is only effective against browsers lacking support for Content-Security-Policy such as Internet Explorer 11. On a Zulip server using the S3 uploads backend, the attack is confined to the origin of the configured S3 uploads hostname and cannot reach the Zulip server itself.
