Summary
When creating a script task or SSH task in a build plan, if the inline script includes a chmod command like chmod +x <filename>, saving the task command results in an error.
No errors appear in the logs, failure appears to be client side. Validate this by confirming no errors are present in atlassian-bamboo.log or by Generating HAR files and analyzing web requests.
Cause
A firewall is blocking "unsafe" text strings from being sent through to the server. "chmod +x" is being detected as potentially unsafe or malicious, and the firewall is preventing the client (web browser) from sending this information through to the Bamboo server
Solution
Resolution
Configure exceptions in firewall for Bamboo
