while writing some articles on our company wiki, I found a strange behavior of the firewall. This is my environment:
PA model: PA-820
PAN-OS version: 10.1.8
APP/Threat version: 8653-7756
Decryption: SSL inbound enabled
I have a policy that allows access to the wiki with applications ssl and web-browsing. When no vulnerability protection profile is applied, I can access all pages of the wiki without any problem. The applications seen are, obviously, only ssl and web-browsing.
If I apply the provided strict vulnerability protection profile, accessing a particular wiki page is denied. The cause is that, when accessing that page, the application is identified as apache-guacamole instead of web-browsing. The wiki page is about installing and configuring Apache Guacamole, but it's not the Guacamole web UI. In the threat log there are no events about any threat detected. If I access the same page in edit mode, the page is not blocked.
These are the URLs involved:
Any idea about the cause of this behavior? It seems to me that the vulnerability protection feature is confusing the APP-ID engine.
