Nessus versions 8.2.1 and earlier were found to contain a stored XSS vulnerability due to improper validation of user-supplied input. An authenticated, remote attacker could potentially exploit this vulnerability via a specially crafted request to execute arbitrary script code in a user's browser session. Tenable has released Nessus 8.2.2 to address this issue.
Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'.
In Nessus before 7.1.0, a XSS vulnerability exists due to improper input validation. A remote authenticated attacker could create and upload a .nessus file, which may be viewed by an administrator allowing for the execution of arbitrary script code in a user's browser session. In other scenarios, XSS could also occur by altering variables from the Advanced Settings.
In Nessus before 7.1.0, Session Fixation exists due to insufficient session management within the application. An authenticated attacker could maintain system access due to session fixation after a user password change.
When installing Nessus to a directory outside of the default location, Nessus versions prior to 7.0.3 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the installation location.
The moment module before 2.19.3 for Node.js is prone to a regular expression denial of service via a crafted date string, a different vulnerability than CVE-2016-4055.
The duration function in the moment package before 2.11.2 for Node.js allows remote attackers to cause a denial of service (CPU consumption) via a long string, aka a "regular expression Denial of Service (ReDoS)."
