Title: OpenAsset Digital Asset Management IP Access Control Bypass Vulnerability Product: OpenAsset Digital Asset Management by OpenAsset Vendor Homepage: https://www.openasset.com/ Vulnerable Version: 12.0.19 (Cloud) 11.2.1 (On-premise) Fixed Version: 12.0.20 (Cloud) 11.4.10 (On-premise) CVE Number: CVE-2020-28856 Author: Jack Misiura from The Missing Link Website: https://www.themissinglink.com.au Timeline: 2020-11-14 Disclosed to Vendor 2020-12-04 Vendor releases final patches 2020-12-10 Publication 1. Vulnerability Description The OpenAsset Digital Asset Management web application allowed for spoofing of IP addresses by using X-Forwarded-For header. By default, the web application would allow all traffic in for 127.0.0.1, in order to prevent users from accidentally blocking themselves. 2. PoC Ensure a web application endpoint has been blocked for a specific IP address or alternatively, use a * to block all IP address. Confirm the block is in place by attempting to make a request to the endpoint. Next, add the following to the request header: X-Forwarded-For: 127.0.0.1 The request will not be blocked, allowing access to potentially dangerous endpoints or sensitive data. 3. Solution The vendor provides an updated version (11.4.10) which should be installed immediately. If using the cloud version, the vendor has already updated it. # 0day.today [2024-11-15] #
