Title: Lotus Domino R5 Server DIIOP DoS Vulnerability
Severity: MODERATE
Description:
Lotus Domino is a multiplatform web server which integrates messaging and various interactive web applications.
DIIOP enables various programs to communicate with Lotus Domino over the internet. When a client request is made, a session is started with the DIIOP protocol. DIIOP listens on TCP port 63148.
A remote attacker could carry out a denial of service attack on a host running Lotus Domino Server. A connection request to port 63148, composed of 10k of data, will establish a DIIOP session. Each such request made will launch a new DIIOP session. By continually submitting requests, an attacker can cause CPU utilization to reach 100% on the target host.
A restart of the service is required in order to gain normal functionality.
Affected Products:
- Lotus Domino 5.0.1
- Lotus Domino 5.0.2
- Lotus Domino 5.0.3
- Lotus Domino 5.0.4
- Lotus Domino 5.0.5
- Lotus Domino 5.0.6
