Description

A vulnerability in the web-based management interface of Cisco HyperFlex software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected system. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. Versions prior to 3.5(1a) are affected.

Affected products

Cisco HyperFlex HX-Series: 2.6(1a), 2.6(1b), 2.6(1d), 2.6(1e), 3.0(1a), 3.0(1b) (+5)
