Major flaw discovery Citrix patches long overdue

According to Citrix, exploitation of this vulnerability could allow an unauthenticated attacker to execute arbitrary code. Customers were first informed about this flaw via a security advisory (with the list of all exposed products). The editor specializing in virtualization has just specified via his blog that patches will be published, but not before January 20. And some versions of the products on display will not have a patch until January 31. Several security researchers have indicated, notably via Twitter, that scans are underway to identify vulnerable servers. Attackers would have enough time to exploit the fault. In addition, proof-of-concept (PoC) exploits have already appeared on Github. Companies using the solutions on display therefore have no time to waste in following the mitigation measures published by Citrix.
