Frontier Transaction calculation

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability has been found in Frontier (unknown version) and classified as critical. Affected by this vulnerability is an unknown code block of the component Transaction Handler. The manipulation with an unknown input leads to a calculation vulnerability. The CWE definition for the vulnerability is CWE-682. The product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. As an impact it is known to affect availability. The summary by CVE is:

Frontier is an Ethereum compatibility layer for Substrate. Prior to commit d3beddc6911a559a3ecc9b3f08e153dbe37a8658, the worst case weight was always accounted as the block weight for all cases. In case of large EVM gas refunds, this can lead to block spamming attacks -- the adversary can construct blocks with transactions that have large amount of refunds or unused gases with reverts, and as a result inflate up the chain gas prices. The impact of this issue is limited in that the spamming attack would still be costly for any adversary, and it has no ability to alter any chain state. This issue has been patched in commit d3beddc6911a559a3ecc9b3f08e153dbe37a8658. There are no known workarounds.

The weakness was published 09/24/2022 as GHSA-v57h-6hmh-g2p4. It is possible to read the advisory at github.com. This vulnerability is known as CVE-2022-39242 since 09/02/2022. The technical details are unknown and an exploit is not publicly available.

Applying the patch d3beddc6911a559a3ecc9b3f08e153dbe37a8658 is able to eliminate this problem. The bugfix is ready for download at github.com.
