Password masking in logs outputs a lot of asterisks if any of the password variable contain an asterisk

Summary

Password masking in logs outputs a lot of asterisks if any of the password variable contain an asterisk and there is more than 1 password variable.

Steps to Reproduce

1. Create 2 variables with password in it's name:
   1. password1 = 123
   2. password2 = *
2. Add a script task that does any command, example echo "Hello"
3. Run the plan

Expected Results

In the build logs, it should show:
password1=********
password2=********

Actual Results

For each password Bamboo would show 512 asterisks

Extent

If you have multiple variables that contain passwords of just asterisks, the number of asterisks will increase by 8 exponent. If there is 10 variables containing just asterisks, Bamboo will create 1 billion asterisks for each password variable in the logs.

Workaround

For Bamboo 5.10.3. This patched jar will prevent the cascading effect of the password masking.

1. Stop Bamboo
2. Backup <bamboo install dir>/atlassian-bamboo/WEB-INF/lib/atlassian-bamboo-api-5.10.3.jar to a separate directory
3. Place this file in the above directory atlassian-bamboo-api-5.10.3.jar
4. Start Bamboo
