IBM Lotus Notes URL Handler Command Execution

Added: 09/07/2012
CVE: CVE-2012-2174
BID: 54070
OSVDB: 83063

Background

Lotus Notes is the client for Lotus Domino servers.

Problem

Lotus Notes 8.5.3 (and earlier) is vulnerable to remote code execution when handling a specially crafted URL. A remote attacker can pass the -RPARAMS command line argument to notes.exe, which then launches rpclauncher.exe. Also supplying the java -vm command allows the attacker to execute arbitrary code in the context of the notes.exe process.

Resolution

Apply the updates as described in the IBM Security Bulletin.
