Technical details
An authentication bypass vulnerability (CWE-302) exists in the Geo replication feature of Dell ECS and ObjectScale. The flaw is rooted in 'assumed-immutable data,' where the system incorrectly trusts certain data elements that should be verified. An unauthenticated remote attacker can exploit this vulnerability to gain unauthorized access to data as it is replicated across geographic sites. The attack requires a high complexity (AC:H), likely involving specific timing or network positioning to intercept or manipulate the replication stream. Dell has released updates to address this issue in ObjectScale version 4.3.0.0 and relevant ECS patches.
Affected products
- Dell ECS 3.8.1.0 - 3.8.1.7
- Dell ObjectScale Prior to 4.3.0.0
