How to Fix CVE-2023-49674

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

io.jenkins.plugins:neuvector-vulnerability-scanner fixed: 2.2 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>neuvector-vulnerability-scanner</artifactId>
    <version>2.2</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=io.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-49674, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugins

Analyze the terminal output to locate any version of Neuvector vulnerability scanner in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins.plugins 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Neuvector vulnerability scanner, 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

Jenkins NeuVector Vulnerability Scanner Plugin 1.22 and earlier does not perform a permission check in a connection test HTTP endpoint. This allows attackers with Overall/Read permission to connect to an attacker-specified hostname and port using attacker-specified username and password. Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. NeuVector Vulnerability Scanner Plugin 2.2 requires POST requests and Overall/Administer permission for the affected HTTP endpoint.
