Back in February, Exodus Intelligence released their blog entry titled 'Execute My Packet', which detailed their discovery and exploitation of CVE-2016-1287. Since then, I've fielded numerous requests for modules and witnessed much discussion generated from it. From this discussion, I've gathered that many researchers seem to consider the Cisco ASA as an unruly beast, difficult to approach, even harder to tame. I feel that this is far from the truth, and this article is a response to such notions. We attempted a module and stopped. Before explaining why, some disclosures may be in order: while I wasn't on this project with David or Jordan, I actually worked at Exodus Intelligence during the discovery of this vulnerability and the initial exploitation attempts. Jordan's original exploit, which the public has seen, is impressive in itself, though not portable across ASA's due to loss of heap determinism given variances in device configurations. I'm positive that given more time, he would have found an information leak necessary to circumvent that. Unfortunately, both he and I left Exodus before the disclosure of the bug, so I can't comment on the decision to release it in such a state. Since the initial disclosure, I've worked both with him and independently to find a fruitful memory disclosure, but to no avail. Given enough time, I'm sure it would come about, but the bug is patched. Releasing a module now that could be used to compromise one's own personal device running an outdated software release feels like a wasted effort at best. Rather, with the aforementioned questions and discussions in mind, I felt that more value would be had in using this as a teaching opportunity. Much of this article will be old hat to many of you, but on that note, you aren't the intended audience. While some people appear to almost fear the ASA, and embedded reverse-engineering in general, I'd argue that this is simply because it is an unknown. I believe this is actually an extremely good way to get one's feet wet in the field. The ASA runs on a common architecture, can be had with a valid license relatively cheap, and requires no electronics knowledge to begin picking apart.
