How to Deal with WooCommerce Vulnerabilities?

WooCommerce Vulnerabilities

As a popular platform used widely across the world, WooCommerce vulnerabilities could be a major trouble for store owners. In case you are impacted with a security vulnerability of WooCommerce, how will you handle it. In this article, we will discuss some of the precautions you can take to deal with WooCommerce vulnerabilities.

WooCommerce Critical Vulnerability July 13th, 2021

A critical vulnerability was reported for WooCommerce and the WooCommerce Blocks plugin on July 13, 2021. This vulnerability was reported by a security researcher Josh through the HackerOne security program of Automattic. Once the vulnerability was detected, there was a thorough investigation by WooCommerce, followed by the development of a security patch. This security patch was deployed automatically to all impacted versions of the plugin.

Recommended actions to tackle July 13 Critical vulnerability

WooCommerce will automatically roll out the security patch on all impacted stores. From a store owner’s perspective, it is recommended that you ensure both WooCommerce and WooCommerce Blocks are updated to their latest versions (5.5.1). It is also preferable to have your passwords updated for admin users. Another suggestion is to rotate API keys and payment gateway keys used on the store.

WooCommerce has also published a list of patch versions in this post, and if your version is not in the list, you can update both WooCommerce and WooCommerce Block plugin to the highest available version.

Reasons for not receiving the security patch automatically

There could be a few reasons for your store not receiving the security patch. These are:

  1. Your store is running on an older version of WooCommerce (lower than version 3.3)
  2. You have disabled automatic updates on your store.
  3. There is a possibility that the file system is read only.
  4. There could be conflicts from some plugins installed on your site.

For stores running on older versions, there is no further action required as this particular security vulnerability won’t have any impact. However, for all the other reasons mentioned above, WooCommerce advises store owners to try manually updating the plugin.

How to find if data was compromised?

According to WooCommerce, there is no definite way to confirm what information was exposed during the exploit. If a site is exposed to this issue, any information stored could be affected. In the case of a WooCommerce store, this could be information about customers, orders or other admin data.

One way of knowing whether this vulnerability was exploited is to check the access logs of your web server. WooCommerce has also provided sample request formats that could indicate a possible exploit attempt. Also, they have provided some IP addresses from which majority of exploit attempts came. You can read more details about this on this post about WooCommerce critical vulnerability.

Is there a possibility of password compromise?

According to WooCommerce, the possibility that this exploit could lead to the compromise of passwords is practically nil. This is because WordPress passwords use cryptographic hash function, and is impossible to crack. If you are following the password management guidelines of WordPress, your password will be secure. However, if a plugin you are using has been storing passwords in less secure ways, there could be an impact.

Suggested precautions

If you are a WooCommerce developer or own a SaaS-based tool based on WooCommerce API, you may have to inform your clients and subscribers about this vulnerability and encourage them to update to a secure version. If you are a WooCommerce store owner, WooCommerce recommends to change any private data stored in your WordPress database such as API keys as well as public or private keys for payment gateway integration. It is also advisable to change the administrator password(s), if they are used in other websites. Resetting passwords of customers is not a necessary step, though you can do it as an additional precautionary measure.
