How to Fix CVE-2023-44311

To remediate this vulnerability, upgrade all affected Com.liferay.oauth2.provider.rest dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.liferay:com.liferay.oauth2.provider.rest fixed: 4.0.51 
<dependency>
    <groupId>com.liferay</groupId>
    <artifactId>com.liferay.oauth2.provider.rest</artifactId>
    <version>4.0.51</version>
</dependency>
com.liferay.portal:release.dxp.bom fixed: 7.4.13.u90 
<dependency>
    <groupId>com.liferay.portal</groupId>
    <artifactId>release.dxp.bom</artifactId>
    <version>7.4.13.u90</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.liferay

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-44311, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.liferay

Analyze the terminal output to locate any version of Com.liferay.oauth2.provider.rest in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.51), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.liferay command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Com.liferay.oauth2.provider.rest, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Multiple reflected cross-site scripting (XSS) vulnerabilities in the Plugin for OAuth 2.0 module's OAuth2ProviderApplicationRedirect class before 4.0.51 from Liferay Portal (7.4.3.41 through 7.4.3.89), and Liferay DXP 7.4 update 41 through update 89 allow remote attackers to inject arbitrary web script or HTML via the (1) code, or (2) error parameter. This issue is caused by an incomplete fix in CVE-2023-33941.
