Severity: 4-Minor


While using the iRules LX Workspace editor, it's possible to see an error if the developer console or other JavaScript console is being used. The error takes the form of: Refused to load the image 'data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==' because it violates the following Content Security Policy directive: "default-src 'self' 'unsafe-inline' 'unsafe-eval'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.


There is no impact. The image trying to be loaded isn't necessary.


Opening files in the iRules LX Workspace editor


The workaround is to upgrade to TMOS v13 or later or upgrade the Chrome version being used.
