How to Fix CVE-2010-0156

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

puppet fixed: 0.24.9

Upgrade puppet to 0.24.9

puppet fixed: 0.25.2

Upgrade puppet to 0.25.2

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for puppet

How to Check if You Are Affected

To determine whether your application is affected by CVE-2010-0156, inspect your project dependencies for Puppet:

inspect dependencies for puppet

Analyze the terminal output to locate any version of Puppet in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.24.9), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-59: Improper Link Resolution Before File Access ('Link Following'), where the product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
