The Tenable Appliance has recently been discovered to contain several vulnerabilities. One exists in the underlying operating system kernel, two in the Appliance web interface, and multiple issues in bundled applications. Since the Appliance ships with other Tenable products, please consult the associated advisories linked below for more details. The following issues were found by Gregor Kopf: Tenable Appliance Web UI Unauthorized Admin Password Manipulation (VulnDB 153134 / CVE-2017-8050) Tenable Appliance Web UI /simpleupload.py tns_appliance_session_user Parameter Remote Command Execution (VulnDB 153135 / CVE-2017-8051) Linux Kernel net/dccp/input.c dccp_rcv_state_process() Function DCCP_PKT_REQUEST Handling Use-after-free Remote Code Execution (VulnDB 152302 / CVE-2017-6074) Tenable Nessus on Windows Unspecified Remote File Upload (TNS-2017-06, VulnDB 152378 / CVE-2017-6543) Tenable SecurityCenter File Upload PHP Object Deserialization Remote File Deletion (TNS-2017-05, VulnDB 152286) Tenable SecurityCenter Multiple Vulnerabilities (TNS-2017-04, See advisory for VDB IDs) Tenable would like to thank Gregor Kopf of Recurity Labs GmbH, working in conjunction with a mutual customer, for discovering and reporting the two Web UI vulnerabilities. The associated CVSSv2 score for this advisory reflects the unauthenticated remote command execution issue. Please note that Tenable strongly recommends that the Tenable Appliance be installed on a subnet that is not Internet addressable. [1] The two vulnerabilities in the Web UI affects all appliances in the 3.x (3.4.0, 3.5.0, 3.5.1, 3.10.0, 3.10.1) and 4.x line (4.0.0, 4.1.0, 4.2.0, 4.3.0, 4.3.1, 4.4.0). Tenable has not tested the third-party code issues to determine how far back in the version line they go. If you are running an appliance prior to 4.5.0, no matter how old, it is strongly encouraged you upgrade to the latest version.
