Description SMASH SMASH 2023-10-16 15:08:18 UTC

The functions to fetch e-mail via POP3 or IMAP as well as sending e-mail via
SMTP use OpenSSL for static SSL or TLS based communication. As the 
SSL_get_verify_result() function is not used the certificated is trusted always
and it can not be ensured that the certificate 
satisfies all necessary security requirements.

This could allow an 
attacker to use an invalid certificate to claim to be a trusted host, 
use expired certificates, or conduct other attacks that could be 
detected if the certificate is properly validated.

This issue affects OTRS: from 7.0.X before 7.0.47, from 8.0.X before 8.0.37;
((OTRS)) Community Edition: from 6.0.X through 6.0.34.

Comment 2 Christian Wittmer 2023-10-17 08:19:12 UTC

OTRS 6 is not supported anymore. And there won't be fixes anymore.
There are to alternatives for Users:
- migration to OTRS community fork _otobo_
  http://download.opensuse.org/repositories/Application:/ITS:/otobo/
- going ahead with paid versions (7 or 8) of OTRS.
