What to do
- Shut down on-premises N-central servers until further notice, as N-able urges
The Brief
- N-able has taken N-central Hosted Environments offline following public disclosure of over 30 vulnerabilities, tracked as Able2Shell.
- A researcher disclosed 33 zero-day vulnerabilities with proof-of-concept exploits.
- N-able is urging on-premises customers to shut down their N-central servers until further notice.
Why it matters
N-central is a remote monitoring and management platform, and public proof-of-concept exploits for its zero-days mean affected servers may be attacked while patches are still pending.
