Recently a "white hat" hacker team was hired by our IT department to probe for vulnerabilities in our intranet, including our JIRA installation. (JIRA was not compromised, btw -- woohoo!). During the exercise, they entered all sorts of script into the JIRA sign-in fields, creating spurious users. I was able to delete all the false accounts except the following two, which still remain in my user list:
These two lines are actually listed as usernames in the Users list. Problem is, when I try to delete them, the operation fails with a java.lang.NullPointerException at
com.atlassian.jira.web.action.admin.user.DeleteUser.doValidation(DeleteUser.java:56)
Is there any way to manually remove these users (perhaps in the database itself)?
