How to Fix CVE-2022-47930

To remediate this vulnerability, upgrade all affected Github.com/bnb chain/tss lib 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/bnb-chain/tss-lib fixed: 2.0.0 
Upgrade github.com/bnb-chain/tss-lib to 2.0.0
github.com/binance-chain/tss-lib fixed: 2.0.0 
Upgrade github.com/binance-chain/tss-lib to 2.0.0
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/bnb-chain/tss-lib

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-47930, inspect your project dependencies for Github.com/bnb chain/tss lib:

inspect dependencies for github.com/bnb-chain/tss-lib

Analyze the terminal output to locate any version of Github.com/bnb chain/tss lib in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.0), 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-294: Authentication Bypass by Capture-replay, where a capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes). In Github.com/bnb chain/tss lib, 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 IO FinNet tss-lib before 2.0.0. The parameter ssid for defining a session id is not used through the MPC implementation, which makes replaying and spoofing of messages easier. In particular, the Schnorr proof of knowledge implemented in sch.go does not utilize a session id, context, or random nonce in the generation of the challenge. This could allow a malicious user or an eavesdropper to replay a valid proof sent in the past.
