What is CVE-2018-1147?

Nessus versions prior to 7.1.0 are vulnerable to a Cross-Site Scripting (XSS) attack due to improper input validation. This flaw allows a remote, authenticated attacker to create and upload a malicious .nessus file. If an administrator views this file, arbitrary script code could be executed in the context of the administrator's browser session, potentially compromising sensitive information. Additionally, XSS could be triggered by manipulating variables in the Advanced Settings. Organizations using affected versions of Nessus should apply the latest updates to mitigate this vulnerability.
