CVE-2019-1908 [High] | Information Disclosure in Unified Computing System

A vulnerability in the Intelligent Platform Management Interface (IPMI) implementation of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to view sensitive system information. The vulnerability is due to insufficient security restrictions imposed by the affected software. A successful exploit could allow the attacker to view sensitive information that belongs to other users. The attacker could then use this information to conduct additional attacks.
