Purpose
Demonstrates SCA reachability analysis for Java on SonarQube.
What this PR does
commons-text:1.9topom.xml(affected by CVE-2022-42889, "Text4Shell")TemplateServlet.javawhich callsStringSubstitutor.replaceSystemProperties(userInput)— a direct, single-hop call to the vulnerable function in the dependencyWhy this triggers reachability
The call graph is clear and shallow:
User-controlled input (
templaterequest parameter) flows directly into the vulnerable method, making this CVE reachable from first-party code.Expected SonarQube result
After analysis, the SCA panel should show
commons-text:1.9withhasReachableLocations: truefor CVE-2022-42889.
