Vulnerabilidades

A path traversal vulnerability in Tenable Agent 11.2.0 and 11.1.3 and lower allows a privileged attacker to write arbitrary files outside the intended plugin directory, potentially leading to remote code execution.

This vulnerability allows an attacker to create a junction, enabling the deletion of arbitrary files with SYSTEM privileges. As a result, this condition potentially facilitates arbitrary code execution, whereby an attacker may exploit the vulnerability to execute malicious code with elevated SYSTEM privileges.

A vulnerability has been identified where weak file permissions in the Nessus Agent directory on Windows hosts could allow unauthorized access, potentially permitting Denial of Service (DoS) attacks.

A vulnerability has been identified in the installation/uninstallation of the Nessus Agent Tray App on Windows Hosts which could lead to escalation of privileges.

In Tenable Agent versions prior to 10.8.5 on a Windows host, it was found that a non-administrative user could execute code with SYSTEM privilege.

In Tenable Agent versions prior to 10.8.5 on a Windows host, it was found that a non-administrative user could arbitrarily delete local system files with SYSTEM privilege, potentially leading to local privilege escalation.

In Tenable Agent versions prior to 10.8.5 on a Windows host, it was found that a non-administrative user could overwrite arbitrary local system files with log content at SYSTEM privilege.

When installing Nessus Agent to a non-default location on a Windows host, Nessus Agent versions prior to 10.8.3 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.

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.

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.

Nessus Agent 8.3.0 and earlier was found to contain a local privilege escalation vulnerability which could allow an authenticated, local administrator to run specific executables on the Nessus Agent host. This is different than CVE-2021-20117.

Nessus Agent 8.3.0 and earlier was found to contain a local privilege escalation vulnerability which could allow an authenticated, local administrator to run specific executables on the Nessus Agent host. This is different than CVE-2021-20118.

The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict…

Nessus Agent versions 7.2.0 through 8.2.2 were found to inadvertently capture the IAM role security token on the local host during initial linking of the Nessus Agent when installed on an Amazon EC2 instance. This could allow a privileged attacker to obtain the token.

A vulnerability in Nessus versions 8.9.0 through 8.12.0 for Windows & Nessus Agent 8.0.0 and 8.1.0 for Windows could allow an authenticated local attacker to copy user-supplied files to a specially constructed path in a specifically named user directory. An attacker could exploit this vulnerability by creating a…

In SQLite through 3.29.0, whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application because of missing validation of a sqlite_stat1 sz field, aka a "severe division by zero in the query planner."
