Some weaknesses and vulnerabilities have been reported in Atlassian JIRA, which can be exploited by malicious users to compromise a vulnerable system and by malicious people to conduct cross-site scripting attacks.
1) The application allows administrative users to e.g. change certain path settings, which can be exploited to gain operating system account privileges to the server infrastructure.
Successful exploitation of these weaknesses requires administrative privileges.
2) Input passed via the "element" or "defaultColor" parameters to the "Colour Picker" page, via the "formName" and "element" parameters and the full user name field to the "User Picker" page, via the "formName" and "element " parameters and the full group name field to the "Group Picker" page, via the "announcement_preview_banner_st" parameter to the "Announcement Banner Preview" page, via the "portletKey" parameter to runportleterror.jsp, via the URL to issuelinksmall.jsp, via the "afterURL" parameter to screenshot-redirecter.jsp, and via the "Referrer" HTTP request header to 500page.jsp is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) Unspecified input passed to the groupnames.jsp, indexbrowser.jsp, classpath-debug.jsp, viewdocument.jsp, and cleancommentspam.jsp scripts is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
NOTE: The vulnerabilities are reportedly being actively exploited in the wild.
Solution: Apply the patches or update to version 4.1.1.
