CVE 2021 3449 exploit method
1 project | /r/PenetrationTesting | 28 Mar 2021

I am trying to understand how to use the information in https://github.com/terorie/cve-2021-3449 to check in my server which has UI and supports TLS 1.2. It does not support renegotiation though but I still wanted to check with exploit to verify whether or not, it is impacted. The link mentions “go run . -host host:port” but I am not able to figure out how to use it as there seem no script to run. Any help would be appreciated.

Does anyone have a PoC? Someone posted this on Github but the git log is squashed and doesn't show the changes they made. https://github.com/terorie/cve-2021-3449
