description

PowerProtect Data Domain Management Center Feature Release 7.7.1.0 through 8.8 and specified LTS builds are affected. A remote attacker with low-privilege access may impersonate authentication and obtain higher permissions, potentially affecting managed Data Domain systems.

mitigation

Upgrade to 8.9.0.0 or later, 7.13.1.90 or later, 8.3.1.50 or later, or 8.6.1.30 or later, as appropriate for the release branch. Until upgrades are complete, limit remote access to trusted low-privilege users.

fixed in 8.9.0.0 or later, 7.13.1.90 or later, 8.3.1.50 or later, 8.6.1.30 or later
