A Server Side Request Forgery (SSRF) vulnerability exists in Tenable.sc due to improper validation of session & user-accessible input data. A privileged, authenticated remote attacker could interact with external and internal services covertly.

A stored cross-site scripting (XSS) vulnerability exists in Tenable.sc due to improper validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

A formula injection vulnerability exists in Tenable.sc due to improper validation of user-supplied input before returning it to users. An authenticated attacker could leverage the reporting system to export reports containing formulas, which would then require a victim to approve and execute on a host.

A LDAP injection vulnerability exists in Tenable.sc due to improper validation of user-supplied input before returning it to users. An authenticated attacker could generate data in Active Directory using the application account through blind LDAP injection.

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.

An authenticated attacker could read Nessus Debug Log file attachments from the web UI without having the correct privileges to do so. This may lead to the disclosure of information on the scan target and/or the Nessus scan to unauthorized parties able to reach the Nessus instance.

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.

An authenticated attacker could read arbitrary files from the underlying operating system of the scanner using a custom crafted compliance audit file without providing any valid SSH credentials.

An authenticated attacker could create an audit file that bypasses PowerShell cmdlet checks and executes commands with administrator privileges.
