Description Pedro Sampaio 2019-05-15 03:24:30 UTC 
A Reflected Cross Site Scripting flaw was found in the pki-ca module from the pki-core server.

In the /ca/agent/ca/profileProcess form, the basicConstraintsPathLen parameter is not properly sanitized by the server and could allow an attacker to inject a specially crafted value that will be executed on the victim's browser.

Comment 7 Cedric Buissart 2019-05-31 10:08:09 UTC 
Statement:

This flaw is considered Low, because it requires the attacker to first request or predict a valid nonce. Without a valid nonce, no arbitrary HTML will be sent back to the victim's browser.

Created pki-core tracking bugs for this issue:

Comment 11 Salvatore Bonaccorso 2020-02-07 06:26:53 UTC 
Do you know if this was reported upstream and there is an upstream fix?
Comment 12 Cedric Buissart 2020-02-07 14:02:04 UTC 
Upstream is aware. There is currently no fix.
However, the security consequences are very limited. 
e.g. : Thanks to the webUI using client side TLS authentication, stealing a cookie will not be of much use to the attacker. 
At the moment, the only concerns are defacing.

If/when there is a fix upstream, it will be posted on this bug tracker.

I hope this helps!
