Cause There are 2 security exposures: - - in the internal HTTP server - - in the external IHS web server The first one has been identified as an ITM product defect. The second one has been identified as a vulnerability to fix and ITM team is working with IHS provider to find a permanent solution. Answer The internal HTTP server exposure is addressed by APAR IV23864 which will be included in ITM 6.2.3 FP3. The external IHS vulnerability is being addressed together with the IHS provider and so far we have a workaround available which is modifying the httpd.conf file. Work-around steps: 1) Locate the httpd.conf file. On Windows %candle_home%\IHS\conf\httpd.conf C:\IBM\ITM\IHS\conf\httpd.conf On Unix $CANDLEHOME/<PLAT>/iu/ihs/conf/httpd.conf /opt/IBM/ITM/*/iu/ihs/conf/httpd.conf 2) Make a backup of httpd.conf to httpd.conf.save 3) Modify httpd.conf a) Locate the line that starts with the word "ServerRoot" b) Insert the following lines after the located line: # disable TRACE in the main scope of httpd.conf RewriteEngine On RewriteCond %{REQUEST_METHOD} ^TRACE RewriteRule .* - [F] RewriteCond %{REQUEST_METHOD} ^TRACK RewriteRule .* - [F] TraceEnable off c) Locate the following line: #LoadModule rewrite_module modules/mod_rewrite.so d) Uncomment the line so that it looks like: LoadModule rewrite_module modules/mod_rewrite.so e) Locate the section: <VirtualHost *:15201> f) Within the section, locate the line that starts "TransferLog" g) Insert the following lines after the located line: # disable TRACE and TRACK in the virtual host RewriteEngine On RewriteCond %{REQUEST_METHOD} ^TRACE RewriteRule .* - [F] RewriteCond %{REQUEST_METHOD} ^TRACK RewriteRule .* - [F] h) Save httpd.conf 4) Restart the HTTP server. You can do this by recycling the Tivoli Enterprise Portal Server. 5) Run the security scan and verify that the vulnerabilities are fixed.
