Summary

Pure Software products are not affected by CVE-2022-42889 (Apache Commons Text) or CVE-2022-33980 (Apache Commons Configuration).

Details

Purity software for FlashArray and FlashBlade do contain the vulnerable software packages as specified by the Apache Project, but the exploitable functions are never used. Additional testing confirms this assessment. Regardless, the relevant packages will be updated as part of Pure's standard processes.

Corrective Action

No corrective action is required for any Pure Storage products.

General Mitigation Best Practices

Pure Storage recommends following network security best practices that minimize the risk of compromise:

  • Restrict management interfaces to a trusted set of networks. Please see Best practices on restricting public IP addresses. Additional security posture hardening may be achieved by restricting all control plane access through a jump box (bastion host).

  • Restrict outbound Internet access to trusted destinations. Phone Home and Remote Assist (RA) require port 443 (https) to be open to CloudAssist subnet 52.40.255.224/27 for outbound traffic. A firewall will need to permit inbound traffic for the established connection. 

  • Pure Storage strongly encourages the widely-endorsed best practice of highly restricting -- if not blocking altogether -- Internet access to management interfaces, including connections via SSH, TLS, remote consoles, and remote desktop mechanisms.

  • Closely monitor arrays for abnormal or unexpected workload/ IO spikes or utilization as a leading indicator.  

  • Enable edge detection/protection mechanisms in the firewall / IDS / IPS systems to detect anomalous access or traffic patterns.
