IBM FlashSystem (IBM Storage Virtualize (8.5.0.0 through 8.5.0.13, 8.5.1.0, 8.5.2.0 through 8.5.2.3, 8.5.3.0 through 8.5.3.1, 8.5.4.0, 8.6.0.0 through 8.6.0.5, 8.6.1.0, 8.6.2.0 through 8.6.2.1, 8.6.3.0, 8.7.0.0 through 8.7.0.2, 8.7.1.0, 8.7.2.0 through 8.7.2.1) could allow a remote attacker to bypass RPCAdapter endpoint authentication by sending a specifically crafted HTTP request.
An attacker sends a specially crafted HTTP request to the RPCAdapter endpoint, which allows them to bypass required identity verification (CWE-288, CWE-306). The authentication mechanism is not properly enforced for this interface, causing the request to be processed without prior authorization. The attack requires no privileges or user interaction and can be conducted remotely over the network.
An attacker can gain unauthorized access to functions exposed by RPCAdapter, leading to a breach of confidentiality and integrity of data stored or managed by the IBM FlashSystem host system.
