Description

A Cross-site scripting (XSS) vulnerability in the Role module's edit role assignees page in Liferay Portal 7.4.0 through 7.4.3.36, and Liferay DXP 7.4 before update 37 allows remote attackers to inject arbitrary web script or HTML.

Technical Analysis

CVE-2022-42114 is a Cross-site Scripting (XSS) vulnerability identified in the Role module's 'edit role assignees' page of Liferay Portal versions 7.4.0 through 7.4.3.36 and Liferay DXP 7.4 prior to update 37. This vulnerability allows remote attackers with at least limited privileges (PR:L) and requiring user interaction (UI:R) to inject arbitrary web scripts or HTML code into the affected page. The vulnerability arises from insufficient input sanitization or output encoding in the role assignee editing interface, which is part of the administrative functionality of Liferay Portal, a widely used enterprise web platform for building portals and websites. Exploitation of this vulnerability could lead to the execution of malicious scripts in the context of the victim's browser session, potentially resulting in session hijacking, privilege escalation, or unauthorized actions within the portal. The CVSS v3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based (AV:N), with low attack complexity (AC:L), but requires privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the security scope of the vulnerable component. Confidentiality and integrity impacts are low, while availability is not affected. No known exploits are currently reported in the wild, and no official patches are linked in the provided data, suggesting that mitigation may require applying the latest Liferay updates or configuration changes once available.

Potential Impact

For European organizations using Liferay Portal or Liferay DXP, this vulnerability poses a moderate risk primarily to administrative users who manage roles and permissions. Successful exploitation could allow attackers to execute malicious scripts within the portal environment, potentially leading to unauthorized access to sensitive information, session hijacking, or manipulation of user roles. This could disrupt business operations, compromise data confidentiality, and undermine trust in the portal's integrity. Given that Liferay is popular among government agencies, educational institutions, and enterprises across Europe for intranet and extranet portals, the impact could extend to critical sectors including public administration, finance, and healthcare. The need for user interaction and existing privilege requirements somewhat limit the attack surface, but insider threats or social engineering could facilitate exploitation. Additionally, the cross-site scripting vulnerability could be leveraged as a stepping stone for more advanced attacks targeting European organizations' web infrastructure.

Mitigation Recommendations

European organizations should prioritize the following specific mitigation steps: 1) Immediately review and restrict administrative privileges to the minimum necessary, ensuring that only trusted users can access the role assignees editing page. 2) Apply the latest Liferay Portal and DXP updates, specifically updating to versions beyond 7.4.3.36 or update 37 where the vulnerability is addressed. 3) Implement Web Application Firewall (WAF) rules to detect and block malicious script injections targeting the role management interface. 4) Conduct thorough input validation and output encoding audits on customizations or extensions related to role management to prevent similar XSS issues. 5) Educate administrators about phishing and social engineering risks to reduce the likelihood of user interaction facilitating exploitation. 6) Monitor logs for unusual activity around role management pages to detect potential exploitation attempts early. 7) Consider deploying Content Security Policy (CSP) headers to mitigate the impact of any injected scripts by restricting script execution contexts.
