Hi,

Where can I find if switches S7700, S5710, S9300, CE6563 are vulnerable to CVE-2021-3449 or CVE-2021-3449 - related to OpenSSL 1.1.1-1.1.1j (released on 25.03.2021) ?

I tried Security Advisory in Product Support but there is no reference to the case


Regards, Piotr Laniec

Hi,
Huawei has announced this vulnerability, and related devices should be patched.
Please refer to:
https://www.huawei.com/ca/psirt/security-notices/huawei-sn-20210210-01-sudo-en
But the device you mentioned should not be involved in this vulnerability.

Sorry I misread it. These are two new vulnerabilities and the bulletin should not have been updated. I guess that using ssl authentication on older devices might be affected by CVE-201-3449(DoS attack).
Anyway, hope you will get an official response soon.

Hi,
I don't think the devices will be vulnerable to CVE-2021-3449. As far as I know, CVE-2021-3449 affects the OpenSSL TLS server while the devices you listed don't support working as a TLS server.
Anyway, that's my viewpoint, and it's better that Huawei provides an official annoucement.

Hi,
Thanks for your reply.
You may be right but switches like s77, S93, ce68 use openssl (check Open Source Software Notice documents for the models) and in V200r019 (v200r009 for CE) it is v1.1.1 of openssl so there might be the case. I do not know the conditions of use (ssl is part of the "internal" software) and there may not be any threat. Nevertheless some other vendors have released statements on the case that's why I think I just have to wait.
