CVE-2021-45046 : NetWitness is monitoring the current situation as it unfolds and as of now, our analysis does not indicate a higher risk. The current mitigation guidance listed here still remain applicable as we work on providing patches that address these vulnerabilities
NetWitness uses Log4j and is vulnerable to the attack. For the vulnerability to be successfully exploited:
The attacker must be able to gain access to the NetWitness Platform login screen
The network allows outbound LDAP connections from NetWitness Platform to external sites
NetWitness Platform 11.4 : If these preconditions are met, then it is theoretically possible to exploit the vulnerability to gain shell access to the NetWitness Platform.
NetWitness Platform 11.5 and later : If these preconditions are met, the Log4j packages cannot be exploited with remote code execution via LDAP, however, it is possible to leak system configuration data.
RSA NetWitness is actively working on patches for 11.5, 11.6 and 11.7 and will follow up with additional communication once that patch is available.
In many environments, we expect the preconditions above not to be met and the vulnerability to be unexploitable. We encourage all customers to validate their systems and take the appropriate immediate action. Please see the mitigation instructions below on how to change your NetWitness Platform deployment to prevent the exploit from succeeding.
All NetWitness Platforms currently supported on 11.4, 11.5, 11.6, 11.7
To mitigate the affected NetWitness deployments, NetWitness administrators should perform the following:
On the NetWitness Admin Server Host and Analyst UI:
1. Append the following parameters to JAVA_OPTIONS:
/etc/default/jetty.user (if jetty.user does not exist, use /etc/default/jetty)
2. Restart jetty as follows:
systemctl restart jetty
For more information on creating custom jetty configuration, see the Manage Custom Jetty Configuration in
the System Maintenance Guide.
NOTE : Depending on the version, these settings may be reverted during a chef run and may need to be configured again. NOTE : For customers on NetWitness 11.4 version, there will be no patch available, and the mitigation steps should be performed.
If you have NetWitness Orchestrator in your deployment, do the following:
Make the following change on the ThreatConnect Application server:
1. Add the following to line 6 of <threatconnect-home>/app/start.sh
For all NetWitness Platform environments, please coordinate with your IT Administrators to ensure there are firewall rules for blocking outbound LDAP connections.
