Some vulnerabilities have been reported in Joomla!, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct cross-site scripting attacks.
1) Certain unspecified input is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in the context of an affected site when the malicious data is displayed.
2) Certain unspecified input passed to the user view of the com_users core component 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) Input passed via certain parameters to the "JA_Purity" template 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.
The vulnerabilities are reported in Joomla! 1.5.10 and all prior 1.5.x releases.
