A vulnerability was found in Honda Vehicle up to 2018. It has been classified as very critical. This affects some unknown processing of the component Remote Keyless Entry. The manipulation with an unknown input leads to a weak authentication vulnerability (RollBack). CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the software does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Remote Keyless Entry (RKE) receiving unit on certain Honda vehicles through 2018 allows remote attackers to perform unlock operations and force a resynchronization after capturing five consecutive valid RKE signals over the radio, aka a RollBack attack. The attacker retains the ability to unlock indefinitely.

The weakness was disclosed 08/24/2022. It is possible to read the advisory at hackaday.com. This vulnerability is uniquely identified as CVE-2022-37305 since 08/01/2022. Technical details are unknown but an exploit is available. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 09/25/2022). Due to its background and reception, this vulnerability has a historic impact.

It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k.
