Port 25
Protocol TCP
Class SMTP
Detailed Description A version of IBM Lotus Domino SMTP server which is older or equal to 6.5.4 is detected as running on the host. Lotus Domino versions prior to 6.5.4 FP1, 6.5.5, and 7.0 are vulnerable to a denial of service in the SMTP service. The vulnerability is due to an error in the "nrouter" module that fails to properly handle malformed meeting requests received via SMTP. A remote attacker could exploit this vulnerability to cause the application to crash or consume a large amount of system resources.

* Note: This check solely relied on the banner of the remote SMTP server to assess this vulnerability, so this might be a false positive.
