How to Fix CVE-2023-46741

To remediate this vulnerability, upgrade all affected Github.com/cubefs/cubefs 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/cubefs/cubefs fixed: 3.3.1 
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-2023-46741, 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.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. 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

A vulnerability was found in CubeFS that could allow users to read sensitive data from the logs which could allow them escalate privileges. CubeFS leaks configuration keys in plaintext format in the logs. These keys could allow anyone to carry out operations on blobs that they otherwise do not have permissions for. For example, an attacker that has succesfully retrieved a secret key from the logs can delete blogs from the blob store. The attacker can either be an internal user with limited privileges to read the log, or it can be an external user who has escalated privileges sufficiently to access the logs. 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 vulnerability has been patched in v3.3.1. There is no other mitigated than upgrading.
