Though the now-infamous Heartbleed bug is currently being patched by many companies on the website level, the OpenSSL data encryption flaw also affects an unknown amount of networking hardware from companies including Cisco Systems.

Cisco published a bulletin on its site, warning that some of its networking hardware and software, which includes routers, Ethernet switches, access points, and more, is affected by the Heartbleed bug, a flaw in the OpenSSL data encryption software used by many of the world’s websites. Though most of this hardware wouldn’t be found in the average person’s home, the hardware that Cisco identifies as vulnerable is likely used by private companies, governments, and other organizations.

We reached out to Cisco for comment, and asked whether a patched website would still be vulnerable to Heartbleed if the organization running the site is still using Cisco hardware and/or services to keep it up and running. Nigel Glennie, Senior Manager of Global Corporate Communcations for Cisco, responded to our request for comment, stating that the list of affected hardware and services “are not going to be the type of products that allow the exploitation of user data on a website.”

However, that seems to run contrary to Cisco’s own bulletin, which states that “Multiple Cisco products incorporate a version of the OpenSSL package affected by a vulnerability that could allow an unauthenticated, remote attacker to retrieve memory in chunks of 64 kilobytes from a connected client or server.” On top of that, the bulletin also states that “disclosed portions of memory could contain sensitive information that may include private keys and passwords.”

Digital Trends is currently awaiting clarification on the apparent discrepancy between Glennie’s statement and Cisco’s published security advisory.

Here’s the list of Cisco networking hardware and services that’s affected by the Heartbleed bug, according to the firm’s official bulletin, as of this writing. Cisco will continue to update these lists, so check back with this Security Advisory page often.
