Vulnerability Note VU#912420

IBM Notes runs arbitrary JAVA and Javascript in emails

Original Release date: 30 Apr 2013 | Last revised: 03 May 2013


IBM Notes parses arbitrary JAVA and Javascript code by default when viewing emails.


The n.runs AG security advisory states:

    Notes 8.5.3 does not filter <applet> tags inside HTML emails. This can be used to load arbitrary Java applets from remote sources (making it an information disclosure as well as this can be used to trigger an HTTP request once the mail is previewed/opened).

Additional details may be found in the full n.runs AG security advisory. It should also be noted that the IBM JRE that comes with the latest patched version of IBM Notes is IBM JRE 6 SR12 while IBM JRE 6 SR13 has been released and includes many security related fixes.


A remote unauthenticated attack may be able to execute arbitrary code in the context of the user viewing emails within IBM Notes.


Apply an Update

IBM's Security Bulletin states:

    The fix will be included in Interim Fix 1 for 8.5.3 Fix Pack 4 and 9.0 Interim Fix 1.
The fix disables loading of JAVA applets for emails that originated from the Internet. Please consider the following workarounds if you are unable to upgrade. We also recommend all users implement the following workarounds if they do not have a need for JAVA & Javascript within Notes.

The following directives should be set to zero in notes.ini to reduce the attack surface.

  • EnableJavaApplets=0
  • EnableJavaScript=0
  • EnableLiveConnect=0

Although not needed to mitigate this vulnerability, if plugins are not needed we recommend the following directive also be set to zero.
  • EnablePlugins=0

Alternatively, in Notes Basic Preferences, deselect the following three preferences:
  • Enable Java applets
  • Enable Java access from JavaScript
  • Enable JavaScript
