EUVDB-ID: #VU25032
Risk: High
CVSSv3.1: 7.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: N/A
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to consensus failure in the network in zcashd, that causes nodes to permanently reject blocks based on their timestamps using subjective information. A remote attacker can isolate the node on the network, potentially tricking a miner or mining pool into rejecting a valid chain. An attacker could have strategically exploited this issue to 51% attack some nodes’ view of the chain and perform double-spending attacks.
MitigationInstall updates from vendor's website.
Vulnerable software versionsZcash: 2.0.0 - 2.1.1
