CVE-2021-42563: Software Security Vulnerability Vulnerability
HIGHCVE-2021-42563 is a HIGH security vulnerability vulnerability (CWE-428: Unquoted Search Path or Element) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. this can cause the product to access resources in a parent path.. Remediation is available in the latest vendor maintenance releases.
CVE-2021-42563 at a Glance
How to Fix CVE-2021-42563
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2021-42563, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree
Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree 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.
