How to Fix CVE-2020-23262

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

net.mingsoft:ms-mcms fixed: 5.1 
<dependency>
    <groupId>net.mingsoft</groupId>
    <artifactId>ms-mcms</artifactId>
    <version>5.1</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=net.mingsoft

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-23262, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=net.mingsoft

Analyze the terminal output to locate any version of Ms mcms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=net.mingsoft 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-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Ms mcms, 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

An issue was discovered in ming-soft MCMS v5.0, where a malicious user can exploit SQL injection without logging in through /mcms/view.do.
