Vendor / product: Broadcom — brocade active support connectivity gateway

When Brocade ASCG before 3.5.0 processes support bundle archives ingested from remote compromised endpoints, the application fails to sanitize path traversal sequences contained within archive entries prior to extraction. An unauthenticated remote attacker capable of sending or intercepting ingested archive files can leverage this flaw to write arbitrary files to restricted locations on the underlying host, potentially leading to remote code execution.
