I found two vulnerabilities in the ShipRocket OpenCart module

One was an Access Bypass as a result of a logic error and type confusion in PHP.

This allows an unauthenticated attacker to access potentially sensitive information stored in the site's database.

This was assigned CVE-2025-0580.

I found an Unrestricted File Upload in the BlogBotz OpenCart module.

This could allow an unauthenticated attacker to gain unauthorised access to the site / hosting infrastructure, for example via a PHP webshell or similar exploit.

This was assigned CVE-2025-0460

I found a SQLi vulnerability in the Dreamvention Live Ajax Search OpenCart module.

This allows an unauthenticated attacker to access any and all content stored in the database.

Via the SQLi vulnerability it's possible to compromise the site by exfiltrating admin session details / credentials.

This was assigned CVE-2025-1116

I found a SQLi vulnerability in the TMD Custom Header Menu OpenCart module.

The CVSS score for this is lower than some of the other SQLi vulnerabilities I found in OpenCart modules, because the vulnerable code is only accessible by authenticated (admin) users.

The maintainers acknowledged the report and fixed this quickly.

This was assigned CVE-2025-0214

It's possible to use the metasploit console and meterpreter as a powerful Command and Control (C2) system using sessions and channels; here's how.

One-liner to start up a multi-handler in the metasploit console listening on a given port for incoming connections from a (staged) metasploit payload:

PHP's create_function() was:

DEPRECATED as of PHP 7.2.0, and REMOVED as of PHP 8.0.0

As the docs say, its use is highly discouraged.

PHP 7 is no longer supported by the upstream developers, but it'll still be around for a while longer (because, for example, popular linux distributions provide support for years beyond the upstream End of Life).

A few years ago I found quite an interesting vulnerability in a contributed Drupal module called tablefield.

The module allows Drupal entities to hold tabular data, and the vulnerability was a combination of Insecure Deserialisation and a type of Insecure Direct Object Reference (IDOR).

The fix was released over 4 years ago so sufficient time has passed for me to share some more details.

The module has a hook_menu page callback (Drupal 7's equivalent of a route) that looks like this:

A couple of years ago I was asked to take a look at a Drupal 7 site that was performing poorly where a colleague had spotted a strange function call in an Application Performance Management (APM) system.

The APM traces we were looking at included a __lamda_func under which was a class called Ratel. Under those were some apparent external calls to some dodgy looking domains.

One of my very excellent colleagues had done some digging and found some more details about the domains which confirmed their apparent dodginess.

My colleagues and I in the Drupal Security Team recently became aware of a Zero Day RCE vulnerability in Ghostscript. This was later assigned CVE-2021-3781.

At least one viable Proof of Concept (PoC) was made public not long after the Zero Day which illustrated Scalable Vector Graphics (SVG) handling in Imagemagick being used as an attack vector.

Easy-to-guess passwords are all too often the means by which intruders gain unauthorised access. It's useful to be able to audit the passwords in use on your site - especially for user accounts with administrative privileges.
