How to Fix CVE-2022-31836

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

github.com/beego/beego fixed: 1.12.11 
Upgrade github.com/beego/beego to 1.12.11
github.com/beego/beego/v2 fixed: 2.0.4 
Upgrade github.com/beego/beego/v2 to 2.0.4
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 github.com/beego/beego

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-31836, inspect your project dependencies for Github.com/beego/beego:

inspect dependencies for github.com/beego/beego

Analyze the terminal output to locate any version of Github.com/beego/beego in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.12.11), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Github.com/beego/beego, 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

The `leafInfo.match()` function in Beego v2.0.3 and below uses `path.join()` to deal with wildcardvalues which can lead to cross directory risk.
