Issue Summary

Provide support for HTTP Strict Transport Security (HSTS) policy mechanism in Fisheye/Crucible as implemented from Bitbucket 8.9. HSTS helps reduce the chances of users accidentally connecting to Fisheye/Crucible over non-secure HTTP connections and prevents man-in-the-middle attacks.

By default, HSTS max-age is set at 2000 in Fisheye/Crucible.

Workaround

1. Create a file byteman_rule.btm on the server hosting Fisheye/Crucible.
2. Add the content below to the file:

   # This is for setting the HSTS max age to the recommended 31536000 in FECRU
   RULE setStsMaxAge
   CLASS com.cenqua.fisheye.web.WebServer
   METHOD addSSLListener
   AT EXIT
   IF true
   DO $src.setStsMaxAge(31536000);
   org.slf4j.LoggerFactory.getLogger("Byteman").info("HSTS max age set successfully");
   ENDRULE
   

3. Set the following environment variables

   If Fisheye/Crucible is installed on a Linux/MacOS you would need to follow these steps to set the environmental variables:

   // Enable Byteman
   export FISHEYE_LOAD_BYTEMAN=1
   // Specify the path to the byteman rule file
   export FISHEYE_BYTEMAN_SCRIPT=</path/to/byteman rule file>
   

   If Fisheye/Crucible is installed as a Windows Service, you would need to follow these steps to set the environmental variables:

   • Stop Fisheye/Crucible Service.
   • Go to <Fisheye installation directory>\bin from the CMD prompt.
   • Run in CMD: service.bat manage
   • Switch to Java tab and append to the java options:

     -javaagent:<Fisheye installation directory>\tools\byteman\lib\byteman.jar=listener:true,script:<\path\to\byteman rule file>\byteman_rule.btm 

   • Apply the changes and close the settings.
4. Restart Fisheye/Crucible
5. From the command line on the server, run the following command to load the Byteman rule

   // Linux
   cd <Fisheye installation directory>/tools/byteman
   ./load-rules.sh </path/to/byteman rule file>/byteman_rule.btm 
   // Windows
   cd <Fisheye installation directory>\tools\byteman
   load-rules.bat <\path\to\byteman rule file>\byteman_rule.btm 
   

6. Restart Fisheye/Crucible. The Strict-Transport-Security max-age would be set at 31536000.
