Advisory Summary

CVE-2021-45465 is a HIGH (CVSS 7.8) security vulnerability vulnerability (CWE-123: Write-what-where Condition) affecting Software libraries in the Maven ecosystem. The weakness occurs when any condition where the attacker has the ability to write an arbitrary value to an arbitrary location, often as the result of a buffer overflow.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2021-45465

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.

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

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-45465, 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.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-123: Write-what-where Condition, where any condition where the attacker has the ability to write an arbitrary value to an arbitrary location, often as the result of a buffer overflow. In Software, 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

A vulnerability has been identified in syngo fastView (All versions). The affected application lacks proper validation of user-supplied data when parsing BMP files. This could result in a write-what-where condition and an attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-15696)
