4.1 · MEDIUMOverview
CVE-2024-42369 is a medium-severity vulnerability affecting matrix javascript_sdk. It was published on August 20, 2024 and has a CVSS 3.1 base score of 4.1 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.1, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. A malicious homeserver can craft a room or room structure such that the predecessors form a cycle. The matrix-js-sdk's getRoomUpgradeHistory function will infinitely recurse in this case, causing the code to hang. This method is public but also called by the 'leaveRoomChain()' method, so leaving a room will also trigger the bug. This was patched in matrix-js-sdk 34.3.1.
Remediation
Check the references section for vendor advisories and patches from matrix. Update javascript_sdk 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.
