- Summary
- NGINX ngx_mail_proxy_module vulnerability
- Details
-
NGINX Plus and NGINX Open Source have a vulnerability in the ngxmailsmtp_module module due to the improper handling of CRLF sequences in DNS responses. This allows an attacker-controlled DNS server to inject arbitrary headers into SMTP upstream requests, leading to potential request manipulation. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
