Dell EMC Unity and UnityVSA Vulnerable to cross-site scripting

Trust: 0.8

sources: JVNDB: JVNDB-2018-011139

DESCRIPTION

Dell EMC Unity and UnityVSA contains reflected cross-site scripting vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability by tricking a victim application user to supply malicious HTML or Java Script code to Unisphere, which is then reflected back to the victim and executed by the web browser. An authorization-bypass vulnerability 2. A cross-site scripting vulnerability 3. The following products are vulnerable: Versions prior to EMC Unity Operating Environment (OE) 4.3.1.1525703027 Versions prior to EMC UnityVSA Operating Environment (OE) versions prior to 4.3.1.1525703027. UnityVSA is another version of it. A remote authenticated user could potentially exploit this vulnerability to read files in NAS server by directly interacting with certain APIs of Unity OE, bypassing Role-Based Authorization control implemented only in Unisphere GUI. Attacker could potentially phish information, including Unisphere users' credentials, from the victim once they are redirected.
