CVE-2023-32623: WordPress Plugin "Snow Monkey Forms" vulnerable to directory traversal

The Subscribe2 plugin for WordPress is vulnerable to unauthorized access to email functionality due to a missing capability check when sending test emails in versions up to, and including, 10.40. This makes it possible for author-level attackers to send emails with arbitrary content and attachments to site users.

CVE-2023-1844: send-email.php in subscribe2/trunk/admin – WordPress Plugin Repository

The Salon Booking System plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 8.4.6. This is due to missing or incorrect nonce validation on the 'save_customer' function. This makes it possible for unauthenticated attackers to change the admin role to customer or change the user meta to arbitrary values via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

CVE-2023-3427: Changeset 2931406 for salon-booking-system – WordPress Plugin Repository

The free tool aims to help organizations meet the requirements of the new version of the payment standard, which takes effect next March.

Jscrambler has released a free tool to help companies check the JavaScript code running on their e-commerce sites and bring them into compliance with the latest PCI DSS (Payment Card Industry Data Security Standards) version 4.0.

PCI Security Standards Council released PCI DSS v4.0 in March 2022 and began a two-year phaseout of the previous versions before beginning enforcement. By March 31, 2025, all retailers and e-commerce sites – anyone who handles payment cards online, really – will need to be in compliance with these requirements. Jscrambler's PCI DSS JavaScript Compliance Tool helps organizations assess whether the JavaScript on their e-commerce sites meet to two v4.0 requirements: protection against (6.4.3) and detection (11.6.1) of skimming attacks on all scripts from a merchant or its third- and fourth-party contractors.

Section 6.4.3 requires that companies confirm that each script is authorized, ensure the integrity of the scripts, and maintain a complete inventory that explains why each script is necessary. Section 11.6.1 applies to merchants that include a third party's iframe payment form on their websites; it compels an evaluation of the HTTP header and payment page periodically (usually every seven days) that looks for and notifies the merchant about any changes to the page.

The anti-skimming requirements are necessary because attackers are launching Web skimming campaigns by injecting malicious code into Magento, WooCommerce, Shopify, and WordPress sites. Magecart skimmers have been found on 2 million websites, including those of Ticketmaster and British Airways.

The Jscrambler tool searches for and collates all scripts on a merchant's site, performing script verification and authorization, and then logging the results, including compliance status. It visualizes each script, highlighting actions that are considered suspicious, analyzes scripts for function and generates justifications for using each. Alerts are triggered if scripts are tampered with, the contents of the payment page are changed without authorization, and the HTTP header is altered. All of these functions reduce manual compliance efforts and assist in generating audit-ready reports, the company said.

WordPress LearnDash LMS version 4.6.0 suffers from an insecure direct object reference vulnerability.

    Description: LearnDash LMS <= 4.6.0 – Authenticated (Subscriber+) Insecure Direct Object Reference to Arbitrary User Password Change Affected Plugin: LearnDash LMSPlugin Slug: sfwd-lmsAffected Versions: <= 4.6.0CVE ID: CVE-2023-3105CVSS Score: 8.8 (High)CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HResearcher/s: Lana Codes Fully Patched Version: 4.6.0.1The LearnDash LMS plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 4.6.0. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for attackers with existing account access at any level, to change user passwords and potentially take over administrator accounts.Technical AnalysisThe LearnDash LMS plugin provides the shortcode ‘[ld_reset_password]‘ to embed a password reset form into a page on a WordPress site. The form allows users to submit their username or email address to receive an email with a password reset link containing a user activation key.Examining the code reveals that the plugin checks that the user activation key belongs to the given user with the learndash_reset_password_verification() function only when displaying the new password form, where the new password can be entered.[View this code snippet on the blog]  However, there is no user activation key check when processing this form. This makes it possible for any authenticated user who has accessed the password reset form via the link sent in the email to modify the password of another user by changing the value of the username hidden input field.[View this code snippet on the blog]  As with any Arbitrary User Password Change that leads to a Privilege Escalation vulnerability, this can be used for complete site compromise. Once an attacker has gained administrative user access to a WordPress site they can then manipulate anything on the targeted site as a normal administrator would. This includes the ability to upload plugin and theme files, which can be malicious zip files containing backdoors, and modifying posts and pages which can be leveraged to redirect site users to other malicious sites.Disclosure TimelineJune 5, 2023 – Discovery of the Arbitrary User Password Change vulnerability in LearnDash LMS.June 5, 2023 – We initiate contact with the plugin vendor asking that they confirm the inbox for handling the discussion.June 5, 2023 – The vendor confirms the inbox for handling the discussion.June 5, 2023 – We send over the full disclosure details.
