curl successfully matches IP address literal in URL against IP address literal in certificate Common Name
hackerone·2021-01-08
curl successfully matches IP address literal in URL against IP address literal in certificate Common Name
curl successfully matches IP address literal in URL against IP address literal in certificate Common Name
## Summary:
A user may invoke the curl command line utility with an IP address literal in the URL, such as
https://192.168.124.2/...
If the HTTPS server presents a certificate whose Common Name matches this IP address literal as a *string* (that is, Common Name is the ASCII string `192.168.124.2`), then curl accepts the certificate (assuming it is properly signed by a trusted CA).
This is wrong. Per [RFC-2818, section *3.1. Server Identity*](https://tools.ietf.org/html/rfc2818#section-3.1):
In some cases, the URI is specified as an IP address rather than a
hostname. In this case, the iPAddress subjectAltName must be present
in the certificate and must exactly match the IP in the U

CVE-2019-14553 [MEDIUM] CVE-2019-14553 edk2: invalid server certificate accepted in HTTPS-over-IPv6 boot
CVE-2019-14553 edk2: invalid server certificate accepted in HTTPS-over-IPv6 boot
edk2 accepts invalid certificates in HTTPS-over-IPv6 boot, which would allow an attacker to perform a man-in-the-middle attack even when HTTPS is used. In particular, the Common Name (CN) of the certificate is not correctly checked, thus the boot succeeds even if it should not be performed.
