We are reaching out to inform you about a critical security vulnerability detected in all CS-Cart versions 4.x.x, including 4.16.2. This issue has the potential to allow malicious users to upload and execute any PHP file on your server.
While there have been no reported cases of exploitation, this issue will likely become widely known within weeks, and malicious actors may begin to target unpatched systems.
Our Services Will Be in High Demand
Due to the severity of this vulnerability, we expect a significant influx of requests for assistance. We will be working on a first-come-first-serve basis, so we highly recommend that you act promptly to secure your position.
Recommended Action: Full Upgrade
Our strong recommendation is a full upgrade to CS-Cart 4.16.2 SP1. This latest version resolves the vulnerability and offers the most robust protection.
Alternative Action: Patch Installation
If a full upgrade is not possible, we can install the “Security Fixes (August 2023) for 4.3.1 - 4.16.x” add-on as a temporary measure.
Note for Earlier Versions:
If you are using versions earlier than 4.3.1, you will need to upgrade to at least version 4.3.1 before applying the security patch.
How to Proceed:
To engage our services, please reply to this email or contact us directly at ecommand.co.uk. Specify your current CS-Cart version, and whether you prefer a full upgrade or patch installation.
Is this something the devs are aware of, or just ecommand trying to scam?
We have indeed released a security patch yesterday. You can either upgrade to version 4.16.2.SP1, or apply the security patch that @smich mentioned. We tried our best to make the installation as easy as an add-on.
Here’s a summary:
There is indeed a vulnerability. It is very important for Multi-Vendor owners to fix it. But if you use Store Builder, you still can — and probably should — apply the fix. Your store will be slightly safer for it.
So far, we have only announced the vulnerability through emails. Forum announcement will come soon as well.
If you haven’t received an email from CS-Cart, it could be because:
either you’re on an older version unaffected by this vulnerability,
or you unsubscribed from our emails in the past.
ecommand.co.uk are on our list of authorized resellers. But we (CS-Cart) usually announce security issues ourselves, to clients and partners alike, and at the same time. But we do not share your email addresses with resellers or partners.
@kingsleypress, @ghiyas, my first guess is that e:command received our email and decided to take a proactive approach in warning their clients. If you never contacted them before, then do not know how they have your email address. Anything I say on the matter would be speculation without any evidence.
For example, I used to receive cold emails from companies that scrape sites all over the Internet, determine those built on platform X/Y/Z etc., find the contact emails, accumulate the data, and then offer spreadsheets like “X/Y/Z users in the United Kingdom”.
Our way to guarantee that the fix is legit is by placing it at https://helpdesk.cs-cart.com, in the “File area”. Just in case, our Help Desk recently got a makeover lately, so don’t be alarmed if it looks better than before
Speaking of “upgrading to latest version” vs “applying an add-on” (to answer @traveler’s question). I’m somewhat biased here — because the more people are using the latest version, the better it is for us. But there are pros and cons to both ways:
Upgrading to the latest version means you get all of the security fixes we’re aware of. It also provodes smaller security improvements that don’t warrant a Service Pack or us bothering you with emails. And whenever we release a new fix, all you have to do is install an SP version.
Installing “Security Fixes” from Help Desk does solve the major security issues — those that can be easily exploited or pose a significant risk to your store or marketplace. This approach might be more appealing when you are on a rather old version and can’t commit to a full upgrade for the moment.
I would assume they’ve used a website like https://builtwith.com who can scrape data such as what platform a website is built with, and they sell that data too to get a list of CS-Cart websites in the UK
I am not in the UK. I have no recollection of having any previous interactions with this company (ecommand.co.uk). I just don’t like it when companies try to trick me into buying their services which turns out to be something I can easily do by myself (upgrade to the Service Pack).
