CVE-2022-21667
Denial of Service in soketi
Description
### Impact _What kind of vulnerability is it? Who is impacted?_ There was a wrong behavior when reading POST requests, making the server crash if it couldn't read the body. In case a POST request was sent to any endpoint of the server with an empty body, **even unauthenticated with the Pusher Protocol**, it would simply just crash the server for trying to send a response after the request closed. All users that run the server are affected by it and it's highly recommended to upgrade to the latest patch. ### Patches _Has the problem been patched? What versions should users upgrade to?_ Updating to at least 0.24.1 or the latest version. ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ No. Upgrading is the only solution. ### References _Are there any links users can visit to find out more?_ https://github.com/soketi/soketi/releases/tag/0.24.1 ### For more information If you have any questions or comments about this advisory: * Open an issue in [the issues board](https://github.com/soketi/soketi/issues) * Email us at [[email protected]](mailto:[email protected])
