Overview

CVE-2023-31290 is a medium-severity vulnerability. It was published on April 27, 2023 and has a CVSS 3.1 base score of 5.9 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.9, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Trust Wallet Core before 3.1.1, as used in the Trust Wallet browser extension before 0.0.183, allows theft of funds because the entropy is 32 bits, as exploited in the wild in December 2022 and March 2023. This occurs because the mt19937 Mersenne Twister takes a single 32-bit value as an input seed, resulting in only four billion possible mnemonics. The affected versions of the browser extension are 0.0.172 through 0.0.182. To steal funds efficiently, an attacker can identify all Ethereum addresses created since the 0.0.172 release, and check whether they are Ethereum addresses that could have been created by this extension. To respond to the risk, affected users need to upgrade the product version and also move funds to a new wallet address.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
