Exploitation Status

any of our products.
Solution
No software updates are required at this time.
NOTE: Cortex XDR Broker VM versions earlier than Cortex XDR Broker VM 17.4.1
contain an affected version of the OpenSSL 3.0 library but are not impacted.
There are no scenarios in Cortex XDR Broker VM software that enable successful
exploitation of these vulnerabilities. The OpenSSL 3.0 library has been removed
from Cortex XDR Broker VM 17.4.1 and later versions for security assurance.
Workarounds and Mitigations
Customers with a Threat Prevention subscription can block known attacks for
CVE-2022-3602 by enabling Threat ID 93212 (Applications and Threats content
update 8638). This mitigation reduces the risk of exploitation from known
exploits.
