The persistent cross-site scripting vulnerability identified as CVE-2022-50797 affects the Stripe Green Downloads WordPress plugin version 2.03, representing a critical security flaw that enables remote attackers to execute malicious scripts through button label fields. This vulnerability resides within the plugin's input validation mechanisms, where user-supplied data intended for button labels fails to undergo proper sanitization before being rendered in the web application's user interface. The flaw allows attackers to inject malicious JavaScript code that persists in the application's database and executes whenever the affected page is loaded, creating a persistent threat vector that can compromise user sessions and application integrity. The vulnerability directly maps to CWE-79, which categorizes cross-site scripting flaws as weaknesses in input validation and output encoding, specifically targeting the failure to properly escape output content. The attack surface extends beyond simple script execution to include session hijacking and unauthorized access to application modules, as the injected scripts can manipulate user sessions and potentially escalate privileges within the WordPress environment.
The technical exploitation of this vulnerability occurs through the manipulation of input parameters within the button label fields of the Stripe Green Downloads plugin, where attackers craft malicious payloads that bypass the plugin's insufficient input validation routines. When administrators or users interact with pages containing these maliciously crafted button labels, the injected scripts execute in the context of the victim's browser, potentially allowing attackers to steal session cookies, modify application behavior, or redirect users to malicious websites. The persistent nature of the vulnerability means that once the malicious code is injected, it remains active until manually removed from the database, creating a long-term threat that can affect multiple users over extended periods. This vulnerability aligns with ATT&CK technique T1566.001, which describes the use of malicious content in web applications to compromise user sessions and execute arbitrary code, and represents a significant risk to WordPress installations that rely on the affected plugin for payment processing functionality.
The operational impact of CVE-2022-50797 extends beyond immediate script execution to encompass potential session hijacking, unauthorized module manipulation, and broader compromise of the WordPress application environment. Attackers can leverage the persistent XSS to establish backdoors within the application, manipulate payment processing workflows, or gain unauthorized access to sensitive administrative functions. The vulnerability particularly affects e-commerce environments where the plugin handles payment buttons and transaction processing, creating opportunities for financial fraud and data theft. Organizations using the affected plugin must consider the potential for cascading effects throughout their web application architecture, as compromised user sessions can lead to further exploitation of interconnected systems. The vulnerability also impacts the trust relationship between users and the website, as persistent XSS can be used to deface pages or redirect users to phishing sites, potentially resulting in significant reputational damage and regulatory compliance issues. Mitigation strategies should include immediate plugin updates, input sanitization implementation, and comprehensive security monitoring to detect and respond to exploitation attempts.
