IDOR Payment Gateway Firm PII Plugin Flaws Vulnerabilities and Exploits WooCommerce Strip Payment WooCommerce WordPress Plugins WordPress

WordPress: Strip Payment Plugin Flaw Exposes Customers' Order Details


A critical vulnerability has recently been discovered in the WooCommerce Gateway plugin for WordPress. Apparently, it has compromised sensitive customer information related to their orders to unauthorized data. On WordPress e-commerce sites, the plugin supported payment processing for over 900,000 active installations. It was susceptible to the CVE-2023-34000 unauthenticated insecure direct object reference (IDOR) bug.

WooCommerce Stripe Payment

WooCommerce Strip Payment is a payment gateway for WordPress e-commerce sites, with 900,000 active installs. Through Stripe's payment processing API, it enables websites to accept payment methods like Visa, MasterCard, American Express, Apple Pay, and Google Pay.

About the Vulnerability

Origin of the Flaw

The vulnerability originated from unsafe handling of order objects and an improper access control measures in the plugin’s ‘javascript_params’ and ‘payment_fields’ functions.

Due to these coding errors, it is possible to display order data for any WooCommerce store without first confirming the request's permissions or the order's ownership (user matching).

Consequences of the Flaw

The payment gateway vulnerability could eventually enable unauthorized users access to the checkout page data that includes PII (personally identifiable information), email addresses, shipping addresses and the user’s full name.

Since the data listed above is listed as ‘critical,’ it could further lead to additional cyberattacks wherein the threat actor could attempt account hijacks and credential theft through phishing emails that specifically target the victim.

How to Patch the Vulnerability?

Users of the WooCommerce Strip Gateway plugin should update to version 7.4.1 in order to reduce the risks associated with this vulnerability. On April 17, 2023, specialists immediately notified the plugin vendor of the vulnerability, CVE-2023-34000. On May 30, 2023, a patch that addressed the problem and improved security was made available.

Despite the patch's accessibility, the concerning WordPress.org data point to risk. The truth is that unsafe plugin versions are still being used by more than half of the active installations. The attack surface is greatly increased in this situation, which attracts cybercriminals looking to take advantage of the security flaw.

Adding to this, the gateway needs safety measures to be taken swiftly like updating version 7.4.1 and ensuring that all plugins are constantly updated, and keeping an eye out for any indications of malicious activities. Website supervisors can preserve sensitive user data and defend their online companies from potential cyber threats by giving security measures a first priority.

Command and Control(C2) Linux Malicious actor Plugin Flaws Spyware URL Vulnerabilities and Exploits Wordpress Vulnerability

WordPress Sites Hit by New Linux Malware

According to an analysis by cybersecurity company Dr. Web, WordPress-based websites are being targeted by an unidentified Linux malware variant.

Recognized as LinuxBackDoor.WordPressExploit.1, while it can also operate on 64-bit Linux versions, the Trojan favors 32-bit versions. 30 vulnerabilities in numerous outdated WordPress plugins and themes have been used by Linux malware.  

Injecting harmful JavaScript into the webpages of websites using the WordPress content management system (CMS) is its primary purpose. The malware may be the malicious instrument that hackers have used for more than three years to perform specific attacks and generate income from the resale of traffic, or arbitrage, based on a study of an unearthed trojan program undertaken by Doctor Web's specialists. 

Malicious actors can remotely operate a Trojan by sending its command and control (C&C) server the URL of the site they want to infect. Threat actors can also remotely disable the spyware, turn it off, and stop recording its activities. 

The researchers described how the process works, adding that if a plugin or theme vulnerability is exposed, the injection is done so that, irrespective of the original contents of the page, the JavaScript would be launched first when the infected page is loaded. By clicking any part of the compromised website, users will be sent to the attackers' preferred website.

Additionally, it can take advantage of many plugins' flaws, including the Brizy WordPress Plugin, the FV Flowplayer Video Player, and the WordPress Coming Soon Page.

According to Dr. Web, both Trojan variants include unreleased functionality for brute-force hacking the admin access of selected websites. Applying well-known logins and passwords while utilizing specialized vocabulary can accomplish this.

The researchers issued a warning, speculating that hackers may be considering using this feature in further iterations of the malware. Cybercriminals will even be able to effectively attack some of the websites that utilize current plugin versions with patched vulnerabilities.

WordPress is reportedly used by 43% of websites, making it a CMS that cybercriminals aggressively target.WordPress website owners are recommended by Dr. Web to update all parts of their platforms, including any third-party add-ons and themes, and to use secure passwords for their accounts.

Jupiter Plugin Flaws Enable Hackers to Hijack Websites

 

According to WordPress security researchers, the Jupiter Theme and JupiterX Core plugins for the WordPress content management system have a variety of vulnerabilities. A major privilege escalation issue is one of these vulnerabilities. 

Privilege escalation is a malicious method that involves acquiring control of a user's account that would otherwise be inaccessible to the present user by exploiting an app or OS flaw or configuration error. By obtaining these rights, a hostile actor can do a variety of actions on the operating system or server, such as executing instructions or assisting malware infection within the network, which can result in business disruption, sensitive data exposure, or system takeover. This is a violation of privilege. 

As per the source, "This vulnerability allows any authenticated attacker, including a subscriber or customer-level attacker, to gain administrative privileges and completely take over any site running either the Jupiter Theme or JupiterX Core Plugin. The JupiterX Core plugin is required for the JupiterX theme. The classic Jupiter Theme contains a function, uninstallTemplate, which is intended to reset a site after a template is uninstalled, but has the additional effect of elevating the user calling the function to an administrator role. In JupiterX, this functionality has been migrated to the JupiterX Core plugin. Vulnerable versions register AJAX actions but do not perform any capability checks or nonce checks."

"On a site with a vulnerable version of the Jupiter Theme installed, any logged-in user can elevate their privileges to those of an administrator by sending an AJAX request with the action parameter set to abb_uninstall_template. This calls the uninstallTemplate function, which calls the resetWordpressDatabase function, where the site is effectively reinstalled with the currently logged-in user as the new site owner. On a site where a vulnerable version of the JupiterX Core plugin is installed, the same functionality can also be accessed by sending an AJAX request with the action parameter set to jupiterx_core_cp_uninstall_template." 

Jupiter is a powerful and high-quality WordPress theme builder. More than 90,000 well-known blogs, online magazines, and platforms with a high volume of user traffic use it. The vulnerability, which has been issued the tracking number CVE-2022-1654 and a CVSS score of 9.9, allows any authorised user on a website that employs vulnerable plugins to get administrator access (critical). 

After successfully exploiting the flaw, attackers have complete control over the website and may do whatever they want with it. This can include altering the site's content, installing dangerous programmes, or completely deleting the site. The attacker only has to be a simple subscriber or client on the website to exploit this vulnerability; thus, it could be said that the attack does not have strict requirements. 

CVE-2022-1654 affects Jupiter Theme 6.10.1 and older (fixed in 6.10.2), JupiterX Theme 2.0.6 and older (fixed in 2.0.7), and JupiterX Core Plugin 2.0.7 and older (fixed in 2.0.8). To improve the security vulnerabilities, one needs to either update to the latest version or disable the plugin and change the site's theme.
