RecoverPoint is disaster recovery software that can be used to back up local and remote data.
In a blog post, Foregenix said it had found ways of exploiting three recently patched vulnerabilities in the RecoverPoint software during a recent pen test.
But during that exercise, Paul Taylor had also found five new zero-day flaws and one insecure configuration option that also constituted a flaw.
The critical vulnerability discovered by Taylor allowed unauthenticated code execution with the privileges of the root user.
"This means, that if an attacker with no knowledge of any credentials has visibility of RecoverPoint on the network, or local access to it, they can gain complete control over the RecoverPoint and its underlying Linux operating system," Foregenix said.
Once control of RecoverPoint devices was gained, an attacker would be able to take advantage of some of the other zero-days discovered to take control of of the Microsoft Active Directory network which with the RecoverPoints were integrated.
The company said it had disclosed the flaws to Dell EMC and security fixes had been released on 18 May.
