Description

Multiple vulnerabilities have been reported in Joomla!, which can be exploited by malicious users to bypass certain security restrictions and by malicious people to conduct cross-site scripting attacks and potentially cause a DoS (Denial of Service).

1) The application does not properly verify authorisation when deleting private messages. This can be exploited to e.g. delete otherwise inaccessible private messages.

2) The application does not properly verify authorisation when viewing permissions. This can be exploited to e.g. disclose otherwise inaccessible permission settings.

3) Certain unspecified input 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.

4) Certain unspecified input related to the Flash-based file uploader 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.

5) Certain unspecified input related to the Voting plugin 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.

6) An unspecified error related to the "unserialize()" function can be exploited to potentially cause a DoS (Denial of Service).

7) Certain unspecified input related to the Highlighter plugin 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 versions prior to 2.5.10 and 3.1.0.
