Security Bulletin, FAQs, and Knowledge Base

  • Security Bulletin 20210511 v1.0 - RUCKUS AP Aggregation And Fragmentation Attacks Vulnerability (aka “FragAttacks”)
  • FragAttacks Vulnerability FAQs - last updated 25 May 2021:  While the FAQs contain many answers to support-related questions, and you should absolutely read them all, we've surfaced these for quick visibility:
    • Q: What if I don’t have an active Support contract with RUCKUS – will I be able to upgrade my software?

      A: Yes. You will be able to obtain the patches that are available for your platform even if you don’t have a current support contract.

    • Q: I picked up the releases you mention, but the release notes do not mention anything about the vulnerabilities. Are they really fixed?
      A: The software versions with fixes and their release notes were made available prior to the public announcements of the FragAttacks vulnerability. In accordance with standard practice, there was an embargo on the public release of information about the vulnerabilities until 11 May 2021. After 11 May 2021, the release notes will be updated to explicitly mention the FragAttacks vulnerability. If you downloaded and installed the software versions mentioned above, please be assured that the fixes are present in the code.
