The inclusion of PuTTY with XenCenter for Citrix Hypervisor 8.2 CU1 LTSR was deprecated with version 8.2.6 of XenCenter and any versions after 8.2.7 will not include PuTTY. An issue has been reported in versions of PuTTY prior to version 0.81; when used in conjunction with XenCenter, this issue may, in some scenarios, allow an attacker who controls a guest VM to determine the SSH private key of a XenCenter administrator who uses that key to authenticate to that guest VM while using an SSH connection. This issue has the following identifier: * CVE-2024-31497 WHAT CUSTOMERS SHOULD DO Customers who do not wish to use the “Open SSH Console” functionality may remove the PuTTY component completely. Customers who wish to maintain the existing usage of PuTTY should replace the version installed on their XenCenter system with an updated version (with a version number of at least 0.81). Note that versions of XenCenter for XenServer 8 have never included PuTTY.
