CVE-2023-38698 is a medium-severity vulnerability affecting ens.domains ethereum_name_service. It was published on August 4, 2023 and has a CVSS 3.1 base score of 4.9 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.9, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum blockchain. According to the documentation, controllers are allowed to register new domains and extend the expiry of existing domains, but they cannot change the ownership or reduce the expiration time of existing domains. However, a preliminary analysis suggests that an attacker-controlled controller may be able to reduce the expiration time of existing domains due to an integer overflow in the renew function. The vulnerability resides `@ensdomains/ens-contracts` prior to version 0.0.22.
If successfully exploited, this vulnerability would enable attackers to force the expiration of any ENS record, ultimately allowing them to claim the affected domains for themselves. Currently, it would require a malicious DAO to exploit it. Nevertheless, any vulnerability present in the controllers could potentially render this issue exploitable in the future. An additional concern is the possibili
Remediation
Check the references section for vendor advisories and patches from ens.domains. Update ethereum_name_service to the latest patched version. 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.
