CVE-2020-17533: Accumulo master Improper Privilege Handling Vulnerability
HIGHCVE-2020-17533 is a HIGH (CVSS 8.1) improper privilege handling vulnerability (CWE-732: Incorrect Permission Assignment for Critical Resource) affecting Accumulo master libraries in the Maven ecosystem. The issue involves improper privilege handling in apache accumulo. Remediation is available by upgrading affected packages to version 1.10.1, 2.0.1.
CVE-2020-17533 at a Glance
Security Impact
CVSS: 8.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).
How to Fix CVE-2020-17533
To remediate this vulnerability, upgrade all affected Accumulo master dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.accumulo</groupId>
<artifactId>accumulo-master</artifactId>
<version>1.10.1</version>
</dependency><dependency>
<groupId>org.apache.accumulo</groupId>
<artifactId>accumulo-master</artifactId>
<version>2.0.1</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.accumuloHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2020-17533, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.accumuloAnalyze the terminal output to locate any version of Accumulo master in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.10.1), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.accumulo 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-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In Accumulo master, 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.
