[R8] Tenable Products Affected by OpenSSL 'CCS Injection' Vulnerability



Multiple products from Tenable Network Security are vulnerable to the recently disclosed OpenSSL 'CCS Injection' vulnerability as they bundle affected versions of the software.

The flaw in OpenSSL is due to a flaw in the handshake process. With a carefully crafted handshake, a remote attacker can force the client or server to use weak keying material. This can then be leveraged to conduct a Man-in-the-Middle (MitM) attack allowing for the decryption or modification of traffic between the victim client and server. This affects the HTTPS web interface of Nessus, SecurityCenter, and PVS, while affecting the proxy server of LCE.

Note that while the CVSS score is 6.8 (Medium), it typically leads to a considerably more severe impact. Both Nessus and PVS currently have plugins that will detect this vulnerability.


Tenable has updated the products to address this issue. Please see the product-specific instructions below:


Tenable has released version 5.2.7 that corresponds to the supported operating systems and architectures. This version bundles the updated OpenSSL library (1.0.0m), which is not affected.

To update your Nessus installation, follow these steps:

  1. Download the appropriate installation file to the system hosting Nessus or Nessus Enterprise, available at the Tenable Support Portal (https://support.tenable.com/support-center/index.php?x=&mod_id=200)
  2. Stop the Nessus service.
  3. Install according to your operating system procedures.
  4. Restart the Nessus service.


Tenable has released a patch for all supported versions of SecurityCenter that addresses this vulnerability. The following patches apply OpenSSL 1.0.1h, which is not affected.:
