NVD Description

Note: Versions mentioned in the description apply only to the upstream nginx-mod-http-perl package and not the nginx-mod-http-perl package as distributed by AlmaLinux.

When the ngx_mail_auth_http_module module is enabled on NGINX Plus or NGINX Open Source, undisclosed requests can cause worker processes to terminate. This issue may occur when (1) CRAM-MD5 or APOP authentication is enabled, and (2) the authentication server permits retry by returning the Auth-Wait response header. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
