[R8] SecurityCenter Affected by OpenSSL 'Heartbleed' Vulnerability



SecurityCenter is vulnerable to the recently disclosed OpenSSL 'Heartbleed' vulnerability as it bundles the software. The flaw in OpenSSL is due to an out-of-bounds read flaw that is triggered during the handling of TLS heartbeat extensions. This may allow a remote unauthenticated attacker to disclose up to 64k of memory at a time, that can contain sensitive information including secret keys, which would allow decryption of all traffic to and from the server. This affects the HTTPS web interface of SecurityCenter.

Note that while the CVSS score is 5.0 (Medium), it typically leads to a considerably more severe impact. Further, Tenable strongly recommends that SecurityCenter and the Tenable Appliance be installed on a subnet that is not Internet addressable.


Tenable has created four archives and they correspond to the supported operating systems and architectures. Each archive contains an updated .so file and an install script that will upgrade OpenSSL to 1.0.1h, which is not affected.

To apply the appropriate patch, follow these steps:

  1. Download the appropriate patch to the system hosting SecurityCenter. Files are named OpenSSL-patch--.tgz. We recommend you put it in /tmp or its own folder.
  2. Untar the patch archive, for example: # tar zxf sc4.7.1-rh6-64.tgz
  3. Run the install script: # ./install.sh

The archives are:
