As part of my research into Gadget Chains and PHP Object Injection, I discovered an unsafe deserialisation vulnerability in The Marketer OpenCart module.

There are Gadget Chains available in Opencart - including a few that I found and submitted to the PHPGGC project:

https://github.com/ambionics/phpggc/pull/199 (not yet merged).

The vulnerability in The Marketer module, combined with these Gadget Chains, allows remote unauthenticated RCE so it got a very high CVSS score.

As part of my research into Gadget Chains and PHP Object Injection, I discovered an unsafe deserialisation vulnerability in the openmass project.

The maintainers responded quickly to the report, and put a fix in place the same day:

The vulnerability was never exposed on the public facing website.

As part of my research into Gadget Chains and PHP Object Injection, I discovered a File Write Gadget Chain in Joomla.

I submitted a PR for this to the excellent PHPGGC project - it will hopefully be Joomla/FW1:

https://github.com/ambionics/phpggc/pull/202 (not yet merged)

I reported this to the Joomla Security Team (before submitting the PR), and they responded quickly.

Unlike some projects I've reported Gadget Chains to, they were grateful for the report and put a fix in place fast:

As part of my research into Gadget Chains and PHP Object Injection, I discovered exploitable vulnerabilities in three different XOOPS modules.

As part of my research into Gadget Chains and PHP Object Injection, I discovered a vulnerability in the Lightning OpenCart module.

(POP/) Gadget Chains exist in OpenCart (3 and 4) which allow Object Injection vulnerabilities to be exploited, for example to write arbitrary files or achieve Remote Code Execution.

The maintainer was very responsive to the report and addressed the issue quickly. Thanks!

As part of my research into Gadget Chains and PHP Object Injection, I discovered an exploitable vulnerability in multiple OpenCart modules named aridius_XYZ.

It appears that current "official" releases of Aridius modules are not vulnerable. However, it also appears to be common for "unofficial" versions of the extensions to be used.

At the time of discovery, at least one such unofficial version was available for free download from the OpenCart marketplace - this release was vulnerable.

The vulnerability is exploitable remotely without authentication.

I found multiple SQLi vulnerabilities in the Coinremitter OpenCart module.

The most serious of these allows an unauthenticated attacker to access any and all content stored in the database.

This potentially exposed credentials for a crypto currency wallet, as well as allowing full compromise of the site.

This was assigned CVE-2025-1117
