Hi Guys,
I saw a looooot of these messages in the logs:
2023-05-09 17:46:31 TLS error on connection from
p4ff64002.dip0.t-ipconnect.de [79.246.64.2] (SSL_accept):
error:0A000126:SSL routines::unexpected eof while reading
2023-05-09 17:47:46 TLS error on connection from
p4ff64002.dip0.t-ipconnect.de [79.246.64.2] (SSL_accept): ret 5
2023-05-09 17:49:01 TLS error on connection from
p4ff64002.dip0.t-ipconnect.de [79.246.64.2] (SSL_accept): ret 5
Does anyone know, what kind of Client/SSL bug causes this exact pattern?
(Exim 4.96/OpenSSL 1.1.1)
I know as fact, that some vulnerablility scanner try to find out if
ports using SSL or not, and cause this messages, but the "ret 5" is
missing when they probe it out. The above log is from a client connect
and the specific user is unable to cooperate on finding out, what setup
bug this might cause(if any).
Thanks,
Marius
