13r2 Service Release 14 (136373)
127224 - App Events: Do not broadcast syslog messages on not authenticated WebSocket connections

13r2 Service Release 17 (136386)
131497 - Advanced UI: Prevent XSL injection
The servlets for the advanced UI accept an "xsl" URL paramter that specifies the XSLT file for displaying the corresponding page.
Before this fix it was possible to specify a DATA URL containing a malicious style sheet that could be used for phishing attacks.
After this fix no values containing a colon are allowed, like:
- xsl=data:...
- xsl=data%3A...
- xsl=data%3a...
- xsl=javascript%3A...
- xsl=http%3A...
- ...
So only the pre-defined style sheets from the box are allowed.

132044 - Fixed command injection vulnerability by modification of service id during app upload
VID-EXA-20220929.1
CVE-2022-41870
Just possible with access to the AP Manager and knowledge of the password of the AP Manager.
The service ID is now validated and must only contain a-zA-Z0-9_- chars.
Thus no command injection vulnerability is possible anymore.
Reported by: Dennis Herrmann of Code White GmbH
Note: the CVE score is wrong (at 7.10.2022), as the CVE has been reported with wrong "Privileges Required" and "User Interaction" tags. Privileges Required must be "High" instead of "None" and User Interaction "Required" instead of "None".
With correct tags, the score would be much lower!
13r2 Service Release 21 (136409)
139670 - Addtional protection against theoretical XSS possibility in pbx_appclient_popup.htm
- The page does not work anymore, if loaded without a window.opener.
- The page does not work anymore, if loaded in a standard browser, just in the myApps launcher.
- The URL-Parameter does not allow data-URLs anymore.
13r2 Service Release 22 (136416)
142560 - App Devices: do not allow to provision a device to a different domain if already provisioned
It is not longer possible to provision a device into another domain if the device is already inside a domain in devices.
If you want to reprovision a device to a different domain, you must first remove it from its current domain.
