The vulnerability identified as CVE-2022-0893 represents a stored cross-site scripting flaw within the pimcore content management platform, specifically affecting versions prior to 10.4.0. This issue resides in the GitHub repository pimcore/pimcore and demonstrates a critical security weakness that allows attackers to inject malicious scripts into web applications that subsequently execute in the context of other users' browsers. The vulnerability manifests when user-supplied input containing malicious code is stored within the application's database and later retrieved without proper sanitization or encoding, creating a persistent XSS vector that can affect multiple users who view the compromised content.
The technical nature of this stored XSS vulnerability stems from inadequate input validation and output encoding mechanisms within the pimcore platform's content handling processes. When administrators or content creators input data containing script tags or other malicious payloads into fields that are subsequently rendered in web pages, the application fails to properly escape or sanitize this content before displaying it to end users. This flaw falls under CWE-79 which specifically addresses Cross-Site Scripting vulnerabilities, and more particularly aligns with CWE-80 which describes stored XSS attacks where malicious scripts are permanently stored on the target server and executed automatically when accessed by other users.
The operational impact of CVE-2022-0893 extends beyond simple script execution as it provides attackers with the capability to hijack user sessions, steal sensitive information, manipulate application data, and potentially escalate privileges within the affected system. Attackers could leverage this vulnerability to execute malicious scripts that capture cookies, redirect users to phishing sites, modify content displayed to other users, or even establish backdoors within the application environment. The persistent nature of stored XSS means that the malicious code remains active until explicitly removed by administrators, potentially allowing attackers to maintain access to the system for extended periods. This vulnerability particularly affects organizations using pimcore for content management, as it undermines the integrity of user sessions and compromises the security of web applications that rely on the platform for their content delivery.
Organizations utilizing pimcore versions prior to 10.4.0 should immediately implement mitigation strategies including upgrading to the patched version 10.4.0 or later, which contains proper input sanitization and output encoding mechanisms. Additional protective measures include implementing robust content security policies, deploying web application firewalls, and conducting thorough security reviews of all user input handling processes. The vulnerability also aligns with several ATT&CK techniques including T1566 for credential access through social engineering and T1059 for command and scripting interpreter execution, highlighting the multi-faceted attack surface this flaw creates. Security teams should also consider implementing automated scanning tools to identify similar vulnerabilities in other applications and establish comprehensive monitoring procedures to detect potential exploitation attempts. The remediation process should include thorough testing of the patched version to ensure no regressions in functionality while maintaining the security improvements that address the stored XSS vulnerability.
