CVE-2022-45064: Apache Sling Engine: Include-based XSS

[Angela Schreiber <angela () apache org>]

Description:

The SlingRequestDispatcher doesn't correctly implement the RequestDispatcher API resulting in a generic type of 
include-based cross-site scripting issues on the Apache Sling level. The vulnerability is exploitable by an attacker 
that is able to include a resource with specific content-type and control the include path (i.e. writing content). The 
impact of a successful attack is privilege escalation to administrative power.




Please update to Apache Sling Engine >= 2.14.0 and enable the "Check Content-Type overrides" configuration option.
