“The issue arises due to inadequate privilege management and could be exploited by an authenticated malicious actor to execute commands without additional authorization,” Netscaler noted.

“However, only authenticated users with existing access to the NetScaler Console can exploit this vulnerability, thereby limiting the threat surface to only authenticated users.”

The shortcoming affects the below versions –

• NetScaler Console 14.1 before 14.1-38.53
• NetScaler Console 13.1 before 13.1-56.18
• NetScaler Agent 14.1 before 14.1-38.53
• NetScaler Agent 13.1 before 13.1-56.18

It has been remediated in the below versions of the software –

• NetScaler Console 14.1-38.53 and later releases
• NetScaler Console 13.1-56.18 and later releases of 13.1
• NetScaler Agent 14.1-38.53 and later releases
• NetScaler Agent 13.1-56.18 and later releases of 13.1

“Cloud Software Group strongly urges customers of NetScaler Console and NetScaler Agent to install the relevant updated versions as soon as possible,” the company said, adding there are no workarounds to resolve the flaw.

That said, customers who are using Citrix-managed NetScaler Console Service do not need to take any action.
