CVE-2023-39910

Summary

CVE-2023-39910: A significant vulnerability was discovered in Libbitcoin Explorer 3.0.0 to 3.6.0, which affects the cryptocurrency wallet's entropy seeding mechanism. The issue stems from the use of an mt19937 Mersenne Twister PRNG, limiting the internal entropy to 32 bits despite user settings. This weakness allows remote attackers to recover any wallet private keys generated from "bx seed" entropy output and subsequently steal funds. Notably, this vulnerability was exploited in the wild in June and July 2023. Despite vendor documentation advising against "bx seed," there is ongoing dispute regarding its adequacy. Affected users are advised to move their funds to a secure new cryptocurrency wallet as soon as possible.
