No Cookie Cutters

Many organizations trying to mature their Application Security Programs are buying SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing) solutions. For those unfamiliar, SAST tools are used for binary, byte, or source code analysis, and look for flaws at the code level, whereas DAST tools are meant to test an application at run time. These tool sets can add a lot of value to an organization, but how they are implemented into the SDLC will determine the true return on investment. Some organizations create a budget, then buy some tools…but beyond that, still need help figuring out next steps. Where there may not be a cookie cutter solution for this, there are common factors that will help you determine the most effective strategy for implementation.

Before we talk about implementing SAST and DAST tools into the SDLC, organizations should first gain an understanding of the size of their application portfolio, how many licenses they can reasonably budget for, and the amount of resources required to implement, tune, support and run these tools. Once those factors are understood, one must put the cart before the horse and ask how the results from these tests will be reviewed, who will review them, and how they will get tracked and prioritized for remediation.

Smaller development shops tend to have tighter budgets and a more tactical approach, given that they may only have one or two application security resources. With environments like this, the development leads are often getting asked for help, and being trained to run the tools themselves so that the application security resources can focus their time on reviewing, validating, analyzing, and tracking the results. Organizations should try to avoid implementing tools which are licensed per user. Why should you have to choose which developer should be able to proactively find issues in the code being developed? The whole purpose of driving automated tools into the SDLC is to encourage all developers to develop based on secure coding principles and be able to test their code as early in the SDLC as possible. When everyone on the development team has the same chance at secure development, a formalized secure coding standard starts to take shape.

Developers leveraging these tools are a very good thing for an organization, but this activity should never replace the more formal review performed by application security professionals. Frequency of testing factors in several other considerations that are a bit off topic for this blog, but may be revisited in a future article.

For issue tracking, the organization may leverage their ticketing, bug tracking, or GRC systems, but needs to also take into consideration what kind of detail is contained within the tickets. In other words, not everyone who can access the tickets should be able to access vulnerability details or application specifics. The ticket should be as generic as possible with details tracked in a system that can be limited to least privilege. Even a developer of one application shouldn’t necessarily have access to the vulnerabilities of another application they don’t work with. It’s important to keep the existence of insider threats in mind when deciding how much detail to reveal within an environment. If the application security issues are available to everyone, and an attack is executed before remediation is in place, this could introduce a great deal of complexity into an internal investigation.

Another important part of the process is aligning the findings that come out of the tools with the security policies/standards that may already be in place. Each tool assigns default levels of severity for each finding. These are typically configurable and should be reviewed, as some organizations may want to change some of these levels based on their own unique environments or controls. It is common for our clients to have a policy or standard in place (whether it be formal or informal) that requires the remediation of all high or medium severity findings prior to code being implemented to production. Ensuring the findings in the tools are configured to help meet this standard also aligns the business and security with the process. It should be noted that if developers can access and run these tools, they should not be able to reconfigure the severity levels themselves and should not deem anything a false positive without a formal review by the security team. Checks and balances are important to maintain, even in a large development shop or organization.

Overall, automated tools are an important part of a Secure SDLC program and provide a lot of value to any development organization. They can help increase the coverage for testing, help identify “low hanging fruit”, and are a great first step to help kick start a new Application Security Program within an existing SDLC. However, organizations must consider implementing usage plans and developing processes to expand the quality and security of the code, as well as provide a much more significant return on investment. Just remember, the solution is as unique as your development environment and overall business. There are no cookie cutter solutions to implementing tools, but GuidePoint is here to help you, and we might even have cookies!

Exim MTA

vSOC SPOT Report: Exim Remote Code Execution Vulnerability


On March 6th, 2018, a security researcher by the name of Meh Chang of Devcore, a Taiwanese security consulting firm, published a remote code execution vulnerability that is present in the mail transfer agent, Exim. Exim is a mail transfer agent (MTA for short) for Unix servers that was developed at the University of Cambridge. Its use is very widespread, estimated to be used on hundreds of thousands of different servers, and it is the default mail transfer agent on some popular web control panels, such as cPanel. It is also the default mail transfer agent in the Debian and Ubuntu Linux distributions. Due to the widespread use of Exim, we believe this vulnerability is particularly dangerous. The vulnerability was first disclosed to Exim on February 2nd, 2018, and a patch was published on February 10th to resolve this issue. This vulnerability is currently being tracked under CVE-2018-6789.

Attack Details

The attack exploits the Base64 decode function of the Exim MTA. The AUTH function of Exim, in most cases, uses Base64 encoding to communicate with the client. Exim uses a buffer to store the decoded Base64 data. Chang found that it was possible to use a certain invalid Base64 string to cause Exim to allocate less space for the buffer than it consumed, creating a buffer overflow. Normally this buffer overflow is harmless, but it is possible to craft the Base64 string to a certain length to overwrite critical data.

Remote execution is possible depending on the use of the Access Control List (ACL) strings in Exim. Chang found that it was possible to overwrite the ACL strings, and then initiate an ACL Check using the ‘MAIL FROM’ SMTP command. When an ACL Check is performed, any code in these strings will be executed if it encounters ${run{cmd}}.

Potential Impact

There have been no known active exploits or proofs of concept of this vulnerability, but this is expected to change in the days following the disclosure due to the ease of exploiting it. Also, the estimated number of machines affected by this vulnerability is very high. A successful exploit of this vulnerability could allow the attacker to gain full access to the mail server. This could then be used to compromise privileged information through the use of reading emails, or the copying, modifying, sending, or deleting of email. This server can then be used as a launching point for further attacks within your network. Even if you are not using Exim within your environment for mail, you could still be vulnerable if Exim is installed and there are open SMTP ports that allow incoming mail.

What You Should Do

Exim has already published Exim 40.9.1 to fix this vulnerability. ALL versions of Exim prior to 40.9.1 are vulnerable to this. Patches are available for Debian, Fedora, SuSE, and Ubuntu Linux distributions as standard packages. Some vulnerability scanners have already added checks for this vulnerability, such as Qualys, Rapid7 and Tenable. We would recommend you review your environment for any indication of vulnerable mail servers and ensure these are updated

GuidePoint’s vSOC will provide additional information as it is made public to help protect our clients.

When user behavioral analytics isn’t the right name

There is a lot of talk about “machine learning” and “behavioral analytics” in the cybersecurity world. Some products and companies are doing a great job designing big data based solutions that use higher math and analytics to find and alert on unusual or malicious activities. Some products are simply a higher order of signatures hiding behind a shiny veneer to make them look like math and analytics.

But sometimes there is a way of doing things that’s simply, well, more than that. There are user behavioral products out there that I think really should be named something different. I’m not sure what that marketing name should be, but let me explain what they do and maybe someone can create a cool shiny name for it.

These products do in fact use math and analytics to baseline activities and alert on deviations, but more importantly, they collect up activities around those deviations and create timelines of total activity and then score them. This is higher order incident response. If you walk into any SOC when a major alert is being investigated, the first thing a SOC analyst will do is collect up evidence and create a timeline of activity around it. Then once all this information is plotted together of “what just happened” they make a decision about whether it was a user who hit something, an application that hiccupped, or the possibility of something much more sinister.

At least one of the user behavioral analytics products does most of that heavy lifting, and does it fast and automatically. Its hands over the timelines and evidence for a human to then validate the “risk score” or invalidate and throw in the trash. Who wouldn’t like to have more time back for their SOC analysts to go proactively hunting instead of reacting? It could be a game changer for many cash and talent strapped agency SOCs.

So, what should these products be called? They aren’t classic automation and orchestration products. They aren’t an IR tool for forensics. They are doing rock star user behavioral analytics, that’s true. Oh alright, I’ll keep calling them user behavioral analytics for now… until someone smarter than me figures out that cool shiny marketing term.

Join GuidePoint Security and Exabeam on March 21st, for a live webinar, to learn more about how they aren’t, well maybe are,  the best User Behavioral Analytics product on the market.  Click here for more information.
