[squid-users] SSL_Bump not working correctly for IP destiantions like https:/1.1.1.1/

[Dieter Bloms]

Hello,

I've a working setup with squid 4.14 and enabled sslbump under debian buster.
But when I try destinations like https://1.1.1.1/ I get an error ERR_CERT_COMMON_NAME_INVALID

The alternate DNS Names in the certificate of the original webserver is:

X509v3 Subject Alternative Name: 
    DNS:cloudflare-dns.com, DNS:*.cloudflare-dns.com, DNS:one.one.one.one, IP Address:1.1.1.1, IP Address:1.0.0.1, IP Address:162.159.36.1, IP Address:162.159.46.1, IP Address:2606:4700:4700:0:0:0:0:1111, IP Address:2606:4700:4700:0:0:0:0:1001, IP Address:2606:4700:4700:0:0:0:0:64, IP Address:2606:4700:4700:0:0:0:0:6400

for the client using the proxy with sslbump it looks like:

X509v3 Subject Alternative Name: 
    DNS:1.1.1.1

so the SAN is a DNS and not an IP Address one.
I think is has to be something like this:

X509v3 Subject Alternative Name: 
    IP Address:1.1.1.1

Can someone confirm this, or may I have a mistake in my squid configuration.

Here some sslbum related details of my config:

http_port MYIP:8080 ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=32MB cert=/etc/squid/cert.pem key=/etc/squid/key.pem tls-dh=/etc/squid/dhparams.pem
http_port MYIP:8880 ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=32MB cert=/etc/squid/cert.pem key=/etc/squid/key.pem tls-dh=/etc/squid/dhparams.pem
sslcrtd_program /usr/sbin/security_file_certgen -s /var/cache/squid/sslcert_db -M 32MB
sslcrtd_children 32 startup=10 idle=3
tls_outgoing_options capath=/etc/ssl/certs min-version=1.2
ssl_bump peek step1

ssl_bump bump all
