Summary
by MITRE • 05/02/2024
The Print Labels with Barcodes. Create price tags, product labels, order labels for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the template and javascript label fields in all versions up to, and including, 3.4.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The vulnerability identified as CVE-2024-1679 affects the Print Labels with Barcodes plugin for WooCommerce, which is widely used for creating price tags, product labels, and order labels within WordPress environments. This plugin serves as a critical component for e-commerce operations, enabling merchants to generate customized labels for their products and orders. The affected version range includes all iterations up to and including 3.4.6, making it a significant concern for WordPress administrators who rely on this functionality for their online stores. The vulnerability stems from inadequate input sanitization and output escaping mechanisms within the plugin's codebase, creating a pathway for malicious actors to exploit the system.
The technical flaw manifests through stored cross-site scripting vulnerabilities in the template and javascript label fields of the plugin. Attackers with subscriber-level access or higher can leverage this weakness to inject malicious scripts into the plugin's template handling mechanisms. These scripts become permanently stored within the application's database and execute whenever legitimate users access pages containing the injected content. The vulnerability specifically targets the plugin's handling of user-supplied data in template and javascript label fields, where insufficient validation and sanitization allows attackers to bypass security controls that should prevent malicious code execution. This represents a classic stored XSS attack vector where the malicious payload persists in the system rather than being executed only during a single request.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform various malicious activities within the compromised WordPress environment. Authenticated attackers with subscriber privileges can manipulate the label generation system to inject scripts that might steal user session cookies, redirect visitors to malicious sites, or even execute commands on the server if additional vulnerabilities exist. The vulnerability affects the entire WordPress ecosystem where the plugin is installed, potentially compromising all users who have access to the label creation functionality. This makes it particularly dangerous in multi-user environments where administrators may not immediately detect the presence of malicious scripts within label templates. The stored nature of the vulnerability means that the malicious code remains active until manually removed, creating an ongoing threat vector that can persist across multiple user sessions and page accesses.
Mitigation strategies for CVE-2024-1679 should prioritize immediate plugin updates to versions that address the identified XSS vulnerabilities, with administrators monitoring for security patches from the plugin developers. Access controls should be reinforced to limit the privileges of users who can create or modify label templates, ensuring that only trusted administrators have elevated permissions within the plugin's functionality. Input validation and output escaping mechanisms should be strengthened throughout the plugin's codebase to prevent similar issues from occurring in future versions. Organizations should implement regular security audits of their WordPress installations, particularly focusing on third-party plugins that handle user-supplied data. The vulnerability aligns with CWE-79 which describes cross-site scripting flaws, and represents a threat that could be categorized under ATT&CK technique T1566 for initial access through malicious content. Network monitoring should be enhanced to detect unusual script execution patterns that might indicate exploitation attempts, while security teams should maintain awareness of the specific attack vectors associated with stored XSS in e-commerce plugin environments.
