How to Fix CVE-2023-34205

To remediate this vulnerability, upgrade all affected Github.com/moov io/signedxml 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/moov-io/signedxml fixed: 1.1.0 
Upgrade github.com/moov-io/signedxml to 1.1.0
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/moov-io/signedxml

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-34205, inspect your project dependencies for Github.com/moov io/signedxml:

inspect dependencies for github.com/moov-io/signedxml

Analyze the terminal output to locate any version of Github.com/moov io/signedxml in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), 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-347: Improper Verification of Cryptographic Signature, where the product does not verify, or incorrectly verifies, the cryptographic signature for data. In Github.com/moov io/signedxml, 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

In Moov signedxml through 1.0.0, parsing the raw XML (as received) can result in different output than parsing the canonicalized XML. Thus, signature validation can be bypassed via a Signature Wrapping attack (aka XSW).
