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:
So only the pre-defined style sheets from the box are allowed.
Reported by trizwo GmbH IT & Communication, trizwo.de.
132044 - Fixed command injection vulnerability by modification of service id during app upload
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!

- The page does not work anymore, if loaded without a window.opener.
