Bitcoin Core vulnerability analysis and mitigation
Overview
bitcoind and Bitcoin-Qt prior to 0.17.1 allow injection of arbitrary data into the debug log via an RPC call (NVD, Bitcoin Wiki). The vulnerability was discovered in 2019 and affects Bitcoin Core and Bitcoin-Qt versions before 0.17.1.
Technical details
The vulnerability is classified as a deception-type flaw that allows debug log injection through unauthenticated RPC access. It has been assigned a CVSS v3.1 Base Score of 5.3 (MEDIUM) with vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N, and a CVSS v2.0 Base Score of 4.3 (MEDIUM) with vector (AV:N/AC:M/Au:N/C:N/I:P/A:N) (NVD).
Impact
The vulnerability allows attackers to inject arbitrary data into the debug log of the Bitcoin client. While this does not directly compromise the security of funds or the network, it could potentially be used for deception or social engineering attacks by manipulating log entries (Bitcoin Wiki).
Mitigation and workarounds
The vulnerability was fixed in Bitcoin Core and Bitcoin-Qt version 0.17.1. Users running affected versions should upgrade to version 0.17.1 or later to mitigate this vulnerability (NVD).
