Category: Magento exploit

Attack code was published on Friday that exploits a critical vulnerability in the Magento e-commerce platform, all but guaranteeing it will be used to plant payment card skimmers on sites that have yet to install a recently released patch. Hackers could exploit the flaw to take administrative control of administrator accounts, assuming the hackers can download user names and password hashes and crack the hashes. From there, attackers could install the backdoors or skimming code of their choice.

A researcher at Web security firm Sucuri said Thursday that company researchers reverse-engineered an official patch released Tuesday and successfully created a working proof-of-concept exploit. The compromises are the result of exploits against either known or zeroday vulnerabilities. A vulnerability of this severity in an e-commerce platform that boastsbusinesses and merchants is almost certainly going to face in-the-wild attacks by the same card-skimmer gangs.

As a result, we can expect another wave of compromises in light of this newly found critical vulnerability. On Friday, a proof-of-concept exploit was published here. That means virtually all Magento sites that haven't installed the patch are susceptible.

A separate technical writeup herealso published Friday, provides additional exploit details, along with the disclosure timeline. Sucuri researcher Marc-Alexandre Montpas concurred with that assessment. Unauthenticated attacks, like the one seen in this particular SQL Injection vulnerability, are very serious, because they can be automated—making it easy for hackers to mount successful, widespread attacks against vulnerable websites.

The number of active installs, the ease of exploitation, and the effects of a successful attack are what makes this vulnerability particularly dangerous. It affects the following versions:. Sites that want to quickly protect themselves from this vulnerability only can install a stand-alone patch. To be fully protected against all vulnerabilities, sites will have to upgrade to Magento Commerce or Open Source 2.

In an emailed statement, Magento officials wrote: "As the majority of exploits tend to target software installations that are not up-to-date with the latest security updates, we always strongly recommend that users install security updates as soon as they are available. A small number of hits to that path may indicate a legitimate request, but more than a couple dozen hits from the same IP address in a few minutes should be considered suspicious. It was updated to report that publicly available exploit code was published less than a day later.

Proof-of-concept Magento exploit used in attacks

It will be a decent amount of work but we've collected our research from the last few client engagements to share with the community to help others who have to work through these issues and that will definitely help you get your environmnet sorted out more quickly than figuring this all out on your own. We've remediated many sites since these exploits were released and to assist the community in responding to them we've documented our research to provide a list of 18 known attack signatures so that you can check your systems for evidence of them and respond accordingly.

Keep in mind we've never seen two compromises that are exactly the same, so there's a chance your particular system might be slightly different - if you discover anything on your system that we don't already have documeted, please share that with us so we can update the attack signature guide. We're working on a toolkit to automate the remediation of these item but it may be a week or two until it's ready for distribution. I'm including a 3-Step Compromise Response Process below that we've worked over and over again to get consistent results.

We provide a link to a guide we've uploaded to our GitHub repo that is tracking the 18 signatures we have been able to clearly identify in the wild that relate to these most recent security announcements.

You should go through each and every one of them to see if you can find anything that matches. If so, you can follow the instructions to either delete or replace the compromised file or delete or update your database to replace the affected data.

It's in PDF format now, but we should have it converted to Markdown by tomorrow. Let me know if you discover anything not included already in that guide - we're trying our best ot keep up with the latest developments on this topic and happily welcome any contributions from the community. You need to go through each one and check to see if you find any evidence on it on your system. Many of them are enough by themselves to allow an attacker to re-enter your systen after you patch it, so you'll have to be dilligent and make sure you don't skip anything or fail to remediate it.

If you're not running one of the latest versions, you can still use the Magento download page to grab older version sources from their site. Contact me at work via AOE - the open web company online! Sign In Help.

Magento patched 37 flaws Thursday, including a stored cross-site scripting XSS vulnerability that could have let an attacker take over a site. Magento patched 37 vulnerabilities on Thursday, including a host of critical flaws in the e-commerce platform that could have let attackers perform a range of malicious activities, such as take over a site and create new admin accounts.

The most serious of the bugs is a remote code-execution RCE vulnerability that could allow an authenticated user, with limited permissions, to create specially crafted newsletters and email templates that can be used to execute arbitrary code on targeted systems. The vulnerability has a CVSS score of 9. This would allow site takeover with the stolen credentials.

On Friday, Ambionics Security released an analysis of the bug and a working proof-of-concept attack model that would allow for extraction of admin sessions or password hashes. The bug has a CVSS score of 9.

InfoSec Insider.Threat actors weaponized a proof-of-concept exploit for a critical vulnerability in Magento after the e-commerce platform patched dozens of flaws last week. The SQL injection vulnerability affected Magento versions 2.

Our team reversed the official patch and successfully created a working proof of concept exploit for internal testing and monitoring. Ambionics Security, a threat assessment firm based in Paris, disclosed the flaw to Magento in November via Bugcrowd. The company warned users on March 25 via Twitter to install the forthcoming patches. On March 27, it tweeted it was going to delay disclosing the technical details of a Magento exploit "to a yet unknown time," because the RCE vector Ambionics disclosed hadn't been patched.

However, on March 29 -- three days after the patches were released -- Ambionics not only posted technical details of the vulnerability, but also posted a proof-of-concept SQL injection Magento exploit. Blaakmeer confirmed via Twitter direct message that he saw more attempts -- "about a dozen over the weekend, spread over several but not all of our shops. Magento urged users to upgrade in order to protect against all known flaws, but also released a patch specifically for the SQL injection vulnerability in case users were unable to upgrade right away.

Magento is a popular open-source e-commerce platform with overshops currently active. This makes it an attractive target for hackers. For the past couple of years, hackers leveraged multiple vulnerabilities to compromise Magento websites and plant malicious scripts that steal payment data on checkout pages. This type of attack is called web skimming and hackers used it to target thousands of websites.

The bug was uncovered by Charles Fola researcher for security company Ambionics. The following versions of Magento are affected by this vulnerability:. To better understand the root cause of the vulnerability, we should take a look at some snippets of Magento code from this file. Here are the relevant lines for the vulnerability:.

At the end of this call, the query becomes:. Our query first turns to:. An issue arises, though, as the next call will be:. The resulting query after the call above then becomes:. The latest versions of Magento already have this fix that removes the CVE vulnerability. To reproduce the vulnerability in a test environment, we ran Magento 2. Here are two examples of GET requests made to the database:.

If the condition evaluates to false, SLEEP 5 is called, and the server will sleep for 5 seconds before responding. Otherwise, we get the response immediately. The original author has already released a proof-of-concept exploit for this vulnerability; however, it is very limited in the amount of information it can extract from the database.

A more generic exploitation method is possible by using SQLMap.
