CVE-2018-7600
Unauthenticated Remote Code Execution in Drupal Core (Drupalgeddon 2)

CVE-2018-7600, widely known as 'Drupalgeddon 2', is an unauthenticated remote code execution flaw in Drupal Core caused by insufficient input validation (CWE-20) in how the CMS processes certain structured request data. It can be triggered through multiple attack vectors, such as crafted parameters submitted to commonly used form and rendering features that are reachable by anonymous users with a single HTTP request. Successful exploitation lets an attacker run arbitrary code under the web application, typically resulting in complete site compromise, and CISA notes the flaw has been used in ransomware operations. Any site running unpatched Drupal 7.x or 8.x core is affected; Drupal's installed base at the time of disclosure was on the order of one million sites. Exploitation is confirmed in the wild (CISA KEV, added 2021-11-03), EPSS assigns a 100% probability of exploitation within 30 days, and no public PoC is recorded in the supplied data.

Do: Upgrade immediately per vendor instructions: Drupal 7.58, 8.5.1, or the corresponding 8.4.6/8.3.9 updates if you remain on older 8.x branches, prioritizing internet-facing sites. Because this flaw has been exploited in the wild and used in ransomware operations, also check patched sites for backdoors, unexpected administrator accounts, modified core files, and rotate credentials.

Two months after the release of the security updates for the drupalgeddon2 flaw, experts continue to see vulnerable websites running on flawed versions of Drupal that hasn’t installed security patches.

In March, the Drupal developers Jasper Mattsson discovered a “highly critical” vulnerability, tracked as CVE-2018-7600, aka drupalgeddon2, affecting Drupal 7 and 8 versions.

Both Drupal 8.3.x and 8.4.x are not supported, but due to the severity of the flaw, the Drupal Security Team decided to address it with specific security updates that were issued a few days later.

The vulnerability that could be exploited by an attacker to run arbitrary code on the CMS core component and take over a website just by accessing an URL.

After the publication of a working Proof-Of-Concept for Drupalgeddon2 on GitHub experts started observing attackers using it to deliver backdoors and crypto miners.

Two months after the release of the security updates, experts continue to see vulnerable websites running on flawed versions of Drupal that hasn’t installed security patches.

According to the security researcher Troy Mursch, there are over 115,000 Drupal sites that have installed security patched for drupalgeddon2 vulnerability.

The researcher found numerous vulnerable sites in the Alexa Top 1 Million, the list includes major US educational institutions, government organizations around the world, a large television network, a multinational mass media and entertainment conglomerate, and two major computer hardware manufacturers.

The expert shared the list of vulnerable websites with US-CERT and other CERT teams worldwide.

Mursch confirmed that cryptojacking campaigns are continuing even after his first report,

“While scanning for vulnerable sites, I discovered a new cryptojacking campaign targeting Drupal sites. One of the affected sites was a police department’s website in Belgium. This campaign uses the domain name upgraderservices[.]cf to inject Coinhive.” added the expert.

The expert published a Google Docs spreadsheet to track the original cryptocurrency mining campaign, the document includes now data on several different campaigns he discovered.

The expert published IoCs for the campaign, the presence online of 115,000 of Drupal 7.x web sites is very danger, a gift for crooks that can abuse them for a broad range of illegal activities.
