Description

This security bulletin contains information about 1 security vulnerability.


1) Information disclosure (CVE-ID: CVE-2018-1323)

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.

Remediation

Install update from vendor's website.
