Upgrade github.com/cubefs/cubefs to 3.3.1
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/cubefs/cubefs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-46742, inspect your project dependencies for Github.com/cubefs/cubefs:

inspect dependencies for github.com/cubefs/cubefs

Analyze the terminal output to locate any version of Github.com/cubefs/cubefs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.1), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In Github.com/cubefs/cubefs, 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

CubeFS was found to leak users secret keys and access keys in the logs in multiple components. When CubeCS creates new users, it leaks the users secret key. This could allow a lower-privileged user with access to the logs to retrieve sensitive information and impersonate other users with higher privileges than themselves. There is no evidence of this vulnerability being exploited in the wild. It was found during an ongoing security audit carried out by [Ada Logics](https://adalogics.com/) in collaboration with [OSTIF](https://ostif.org/) and the [CNCF](https://www.cncf.io/). The issue has been patched in v3.3.1. There is no other mitigation than upgrading CubeFS.
