CVE-2017-9979 describes a Cross-Site Scripting (XSS) vulnerability in OSNEXUS QuantaStor v4 virtual appliances prior to version 4.3.1. This flaw allows an attacker to inject arbitrary HTML or JavaScript into error responses when an invalid REST call is made, as the response is not properly sanitized. Rated Medium with a CVSS score of 6.1, the attack requires user interaction (UI:R) but can lead to client-side information disclosure and integrity compromise (C:L, I:L). While not listed in KEV and with no active exploitation observed, public exploit code (EDB-42517) is available, though community discussion and media coverage are minimal.
