MPSB04-04 Security Patch available for ColdFusion MX and JRun 4.0 Web Services DoS
Originally posted: March 15, 2004
Last updated: March 15, 2004
Summary
ColdFusion MX and JRun 4.0 Web Services may be vulnerable to a Denial-of-Service attack from maliciously constructed SOAP requests.
ColdFusion Version 5 and earlier versions and JRun 3.1 and earlier versions do not support Web Services and are not vulnerable.
If using Web Services with ColdFusion MX or JRun 4.0, this fix should be applied if either:
- the Web Services are available publicly
- the Web Services may be accessed by a potential attacker
NOTE: This fix is NOT required if ColdFusion MX or JRun 4.0 is used only to consume Web Services provided by others. Also, the default ColdFusionMX and JRun 4.0 installations are not vulnerable because they do not contain any deployed web services.
NOTE: JRun 4 Updater 3 users are not vulnerable.
This fix supplies a replacement webservices.jar. This replacement webservices.jar is not vulnerable to the Denial-of-Service attack.
