Detailed vulnerability description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to incorrect handling of some edge cases by the IIS/ISAPI specific code that normalised the requested path before matching it to the URI-worker map. A remote attacker can send a specially constructed request to expose application functionality through the reverse proxy that was not intended for clients accessing the application via the reverse proxy.

How to mitigate CVE-2018-1323

Update to version 1.2.43.
