Detailsinfo

A vulnerability, which was classified as problematic, has been found in Bitcoin Core and Bitcoin Knots (unknown version). Affected by this issue is an unknown code block of the component Final Alert Handler. The manipulation with an unknown input leads to a cryptographic issue vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is availability. CVE summarizes:

In Bitcoin Core before v0.13.0, a non-final alert is able to block the special "final alert" (which is supposed to override all other alerts) because operations occur in the wrong order. This behavior occurs in the remote network alert system (deprecated since Q1 2016). This affects other uses of the codebase, such as Bitcoin Knots before v0.13.0.knots20160814 and many altcoins.

The bug was discovered 07/02/2018. The weakness was published 07/05/2018 (Website). The advisory is shared for download at en.bitcoin.it. This vulnerability is handled as CVE-2016-10725 since 06/25/2018. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.

The vulnerability was handled as a non-public zero-day exploit for at least 3 days. During that time the estimated underground price was around $0-$5k.

Upgrading eliminates this vulnerability.
