From remote

Impact:

Security Bypass, Cross Site Scripting, Manipulation of data, DoS

CVE Reference(s):

Description


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

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) Input passed via HTTP cookies to plugins/system/remember/remember.php is not properly sanitized before being used in an "unserialize()" function call. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code and delete arbitrary directories.

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.


Solution:
Update to version 2.5.10 or 3.1.0.
