CVE-2022-38902: n/a in n/a
A Cross-site scripting (XSS) vulnerability in the Blog module - add new topic functionality in Liferay Digital Experience Platform 7.3.10 SP3 allows remote attackers to inject arbitrary JS script or HTML into the name field of newly created topic.
AI Analysis
Technical Summary
CVE-2022-38902 is a Cross-Site Scripting (XSS) vulnerability identified in the Blog module's 'add new topic' functionality of Liferay Digital Experience Platform (DXP) version 7.3.10 SP3. This vulnerability allows remote attackers with limited privileges (PR:L) to inject arbitrary JavaScript or HTML code into the 'name' field when creating a new topic. The injected script can then be executed in the context of other users who view the affected content, potentially leading to session hijacking, defacement, or redirection to malicious sites. The vulnerability requires user interaction (UI:R), meaning the victim must view the maliciously crafted topic for exploitation to occur. 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 requiring privileges and user interaction. The vulnerability impacts confidentiality and integrity but does not affect availability. No known exploits are currently reported in the wild, and no official patches or vendor advisories are linked in the provided data. The CWE classification is CWE-79, which is a common and well-understood category of XSS vulnerabilities. Given the nature of Liferay DXP as a widely used enterprise portal and content management system, this vulnerability could be leveraged to compromise user sessions or inject malicious content within corporate intranets or public-facing portals.
Potential Impact
For European organizations using Liferay DXP 7.3.10 SP3, this vulnerability poses a moderate risk primarily to the confidentiality and integrity of user data. Exploitation could lead to unauthorized access to user sessions, data leakage, or manipulation of displayed content, potentially damaging organizational reputation and user trust. Since Liferay is often used for internal collaboration portals, intranets, and customer-facing websites, successful exploitation could facilitate phishing attacks or lateral movement within corporate networks. The requirement for limited privileges and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments with many users and frequent content creation. Regulatory frameworks such as GDPR emphasize the protection of personal data, and exploitation leading to data breaches could result in compliance violations and financial penalties. Additionally, the medium severity score suggests that while the vulnerability is not critical, it should be addressed promptly to prevent escalation or chaining with other vulnerabilities.
Mitigation Recommendations
European organizations should implement the following specific mitigations: 1) Apply any available vendor patches or updates for Liferay DXP 7.3.10 SP3 as soon as they are released. In the absence of official patches, implement input validation and output encoding on the 'name' field in the Blog module to sanitize user inputs and prevent script injection. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the web application context. 3) Limit privileges for users who can create or edit blog topics to trusted personnel only, reducing the risk of malicious input. 4) Conduct regular security audits and penetration testing focused on web application vulnerabilities, including XSS. 5) Educate users to recognize suspicious content and avoid interacting with untrusted links or topics. 6) Monitor web application logs for unusual input patterns or error messages that may indicate exploitation attempts. 7) Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting the Liferay platform. These measures collectively reduce the likelihood and impact of exploitation beyond generic advice.
