When installing Nessus Agent to a directory outside of the default location on a Windows host, Nessus Agent versions prior to 10.6.4 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location.

A race condition vulnerability exists where an authenticated, local attacker on a Windows Nessus host could modify installation parameters at installation time, which could lead to the execution of arbitrary code on the Nessus host

When installing Nessus to a directory outside of the default location on a Windows host, Nessus versions prior to 10.7.3 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location.

As a part of Tenable’s vulnerability disclosure program, a vulnerability in a Nessus plugin was identified and reported. This vulnerability could allow a malicious actor with sufficient permissions on a scan target to place a binary in a specific filesystem location, and abuse the impacted plugin in order to escalate privileges.

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.

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 command injection vulnerability exists where an authenticated, remote attacker with administrator privileges on the Security Center application could modify Logging parameters, which could lead to the execution of arbitrary code on the Security Center host.

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, 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.
