Advisory Summary

CVE-2026-104810 is a HIGH security vulnerability vulnerability (CWE-31: Path Traversal: 'dir\..\..\filename') affecting Software libraries in the Maven ecosystem. The weakness occurs when the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize 'dir\..\..\filename' (multiple internal backslash dot dot) sequences that can resolve to a location that is outside of that directory.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-104810

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-2026-104810, 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-31: Path Traversal: 'dir\..\..\filename', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize 'dir\..\..\filename' (multiple internal backslash dot dot) sequences that can resolve to a location that is outside of that directory. 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

This vulnerability allows remote attackers to delete sensitive files on vulnerable installations of Mitel MiVoice Office 400. Authentication is required to exploit this vulnerability. The specific flaw exists within the web portal listening on TCP port 443, under Maintenance → File Management → File Browser, which is affected by a directory traversal vulnerability. By exploiting this vulnerability, an authenticated attacker can access and delete files outside of the intended directory, including files belonging to the Mitel application and the underlying Linux system. Deleting critical system or application files can result in a denial-of-service condition affecting the underlying system.
