Description:
A weakness has been reported in IBM WebSphere Application Server, which can be exploited by malicious people to disclose system information.
The problem is that the serveServletsByClassnameEnabled is by default set to true, which allows certain information to be disclosed (e.g. Java Class name). This information may aid an attacker when looking for ways to attack a site.
The weakness is reported in the following versions:
For Distributed:
* 6.1.0.9 through 6.1.0.13
* 6.1.0.2 through 6.1.0.7
* 6.1 through 6.1.0.1
* 6.0.2.25
* 6.0.2.13 through 6.0.2.23
* 6.0.2.9 through 6.0.2.11
* 6.0.2.5 through 6.0.2.7
* 6.0.2 through 6.0.2.3
* 6.0.1 through 6.0.1.2
* 6.0 through 6.0.0.3
For i5/OS:
* 6.1 through 6.1.0.14
* 6.0.2.13 through 6.0.2.23
* 6.0.2 through 6.0.2.12
For z/OS:
* 6.1 through 6.1.0.14
* 6.0.2 through 6.0.2.25 for z/OS.
NOTE: The default setting of serveServletsByClassnameEnabled in versions 5.1, 5.0 and 4.0 is false.
