How to Fix CVE-2023-47320

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

org.silverpeas.core:silverpeas-core-war fixed: 6.3.2 
<dependency>
    <groupId>org.silverpeas.core</groupId>
    <artifactId>silverpeas-core-war</artifactId>
    <version>6.3.2</version>
</dependency>
org.silverpeas.core:silverpeas-core-web fixed: 6.3.2 
<dependency>
    <groupId>org.silverpeas.core</groupId>
    <artifactId>silverpeas-core-web</artifactId>
    <version>6.3.2</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=org.silverpeas.core

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-47320, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.silverpeas.core

Analyze the terminal output to locate any version of Silverpeas core war in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.3.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.silverpeas.core 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Silverpeas core war, 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

Silverpeas Core 6.3.1 is vulnerable to Incorrect Access Control. An attacker with low privileges is able to execute the administrator-only function of putting the application in "Maintenance Mode" due to broken access control. This makes the application unavailable to all users. This affects Silverpeas Core 6.3.1 and below.
