A SQL injection vulnerability exists where an authenticated, low-privileged remote attacker could potentially alter scan DB content.

A stored XSS vulnerability exists where an authenticated, remote attacker with administrator privileges on the Nessus application could alter Nessus proxy settings, which could lead to the execution of remote arbitrary scripts.

An arbitrary file write vulnerability exists where an authenticated attacker with privileges on the managing application could alter Nessus Rules variables to overwrite arbitrary files on the remote host, which could lead to a denial of service condition.

An arbitrary file write vulnerability exists where an authenticated, remote attacker with administrator privileges on the Nessus application could alter Nessus Rules variables to overwrite arbitrary files on the remote host, which could lead to a denial of service condition.

Under certain conditions, a low privileged attacker could load a specially crafted file during installation or upgrade to escalate privileges on Windows and Linux hosts.

An improper authorization vulnerability exists where an authenticated, low privileged remote attacker could view a list of all the users available in the application.

An arbitrary file write vulnerability exists where an authenticated, remote attacker with administrator privileges could alter logging variables to overwrite arbitrary files on the remote host with log data, which could lead to a denial of service condition.

A pass-back vulnerability exists where an authenticated, remote attacker with administrator privileges could uncover stored SMTP credentials within the Nessus application.This issue affects Nessus: before 10.6.0.

A vulnerability was reported where through modifying the scan variables, an authenticated user in Tenable products, that has Scan Policy Configuration roles, could manipulate audit policy variables to execute arbitrary commands on credentialed scan targets.

A privilege escalation vulnerability was identified in Nessus versions 8.10.1 through 8.15.8 and 10.0.0 through 10.4.1. An authenticated attacker could potentially execute a specially crafted file to obtain root or NT AUTHORITY / SYSTEM privileges on the Nessus host.

An authenticated attacker could utilize the identical agent and cluster node linking keys to potentially allow for a scenario where unauthorized disclosure of agent logs and data is present.

Insufficiently Protected Credentials: An authenticated user with debug privileges can retrieve stored Nessus policy credentials from the “nessusd” process in cleartext via process dumping. The affected products are all versions of Nessus Essentials and Professional. The vulnerability allows an attacker to access credentials stored in Nessus scanners, potentially compromising its customers’ network of assets.
