How to Fix CVE-2020-10937

To remediate this vulnerability, upgrade all affected Github.com/ipfs/go ipfs 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/ipfs/go-ipfs fixed: 0.7.0 
Upgrade github.com/ipfs/go-ipfs to 0.7.0
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/ipfs/go-ipfs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-10937, inspect your project dependencies for Github.com/ipfs/go ipfs:

inspect dependencies for github.com/ipfs/go-ipfs

Analyze the terminal output to locate any version of Github.com/ipfs/go ipfs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.0), 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Github.com/ipfs/go ipfs, 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

An issue was discovered in IPFS (aka go-ipfs) 0.4.23. An attacker can generate ephemeral identities (Sybils) and leverage the IPFS connection management reputation system to poison other nodes' routing tables, eclipsing the nodes that are the target of the attack from the rest of the network. Later versions, in particular go-ipfs 0.7, mitigate this.
