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 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.

As part of our Security Development Lifecycle, a potential privilege escalation issue was identified internally. This could allow a malicious actor with sufficient permissions to modify environment variables and abuse an impacted plugin in order to escalate privileges. We have resolved the issue and also made several defense-in-depth fixes alongside. While the probability of successful exploitation is low, Tenable is committed to securing our customers’ environments and our products. The updates have been distributed via the Tenable plugin feed in feed serial numbers equal to or greater than #202212212055.

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.

DLL Injection in Tenable Identity Exposure Secure Relay

A DLL injection vulnerability exists where an authenticated, low-privileged local attacker could modify application files on the TIE Secure Relay host, which could allow for overriding of the configuration and running of new Secure Relay services.

Arbitrary File Write

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.

Improper privilege management

An improper privilege management vulnerability exists in Tenable Security Center where an authenticated, remote attacker could view unauthorized objects and launch scans without having the required privileges

Stored Cross Site Scripting

A stored cross site scripting vulnerability exists in Tenable Security Center where an authenticated, remote attacker could inject HTML code into a web application scan result page.

HTML Injection Vulnerability

An HTML injection vulnerability exists where an authenticated, remote attacker with administrator privileges on the Security Center application could modify Repository parameters, which could lead to HTML redirection attacks.

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

Stored XSS vulnerability

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.

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.

Blind SQL Injection

Under certain conditions, Nessus Network Monitor was found to not properly enforce input validation. This could allow an admin user to alter parameters that could potentially allow a blindSQL injection.

Privilege Escalation

NNM failed to properly set ACLs on its installation directory, which could allow a low privileged user to run arbitrary code with SYSTEM privileges where NNM is installed to a non-standard location

Privilege Escalation

Under certain conditions, Nessus Network Monitor could allow a low privileged user to escalate privileges to NT AUTHORITY\SYSTEM on Windows hosts by replacing a specially crafted file.

Improper authorization in Nessus

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

Arbitrary File Write

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.
