Affected EdgeConnect SD-WAN Gateways versions: 9.7.0 and earlier; 9.6.0 through 9.6.3; 9.5.0 through 9.5.8, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Edgeconnect Sd-wan Orchestrator to 9.4.11 or 9.5.9 or 9.6.4, whichever matches your release line, or a later version.
- Update Edgeconnect Operating System to 9.4.9.0 or 9.5.9.0 or 9.6.4.0, whichever matches your release line, or a later version.
- Read the advisory on support.hpe.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
