|Product |VRMF |APAR |Remediation/First Fix |
+----------+---------+------------+---------------------------------------------------------------------------+
| | | |Steps to download and replace JRE in IBM Security AppScan Enterprise: |
| | | |1. Download AppScanEnterprise-JavaSE-SDK-8.0.5.15-Windows from http:// |
| | | |www.ibm.com/support/fixcentral/quickorder?product= |
| | | |ibm%2FRational%2FRational+AppScan+Enterprise+Edition&fixids= |
| | | |AppScanEnterprise-JavaSE-SDK-8.0.5.15-Windows&source=SAR |
| | | |2. Steps to replace JRE: |
| | | | |
| | | | o Unzip the downloaded JRE zip file to a directory. |
| | | | o Stop the IBM Security AppScan Enterprise Server service from the |
| | | | Service Control Manager. |
| | | | o Move %ASE_HOME%\java\jre folder to backup folder. |
| | | | o Move %ASE_HOME%\Liberty\jre folder to backup folder. |
|IBM | | | o Copy the unzipped jre folder to %ASE_HOME%\java\ and %ASE_HOME%\Liberty|
|Security | | | \ folders. |
|AppScan | | | o Start the IBM Security AppScan Enterprise Server service from the |
|Enterprise|9.0.3.x |N/A | Service Control Manager. |
+----------+---------+------------+---------------------------------------------------------------------------+
To verify if IBM Security AppScan Enterprise has JRE version to address above
security vulnerabilities:
Open a command prompt
Go to %ASE_HOME%\java\jre\bin folder Execute java -version
Example Output:- java version "1.8.0_171" Java(TM) SE Runtime Environment (build
8.0.5.15 - pwi3280sr5fp15-20180502_01(SR5FP15)) IBM J9 VM (build 2.9, JRE 1.8.0
Windows Server 2012 R2 x86-32 20180425_385365 (JIT enabled, AOT enabled)
If the output version is 8.0.5.15 or greater than 8.0.5.15, it implies that the
JRE addresses these security vulnerabilities.
