CVE Reference(s):

Description


Some vulnerabilities have been reported in Textpattern, which can be exploited by malicious users to disclose sensitive information or conduct script insertion attacks, and by malicious people to conduct cross-site scripting attacks.

1) Input passed to an unspecified parameter in textpattern/index.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.

Successful exploitation requires publisher privileges.

2) Input passed as the "Body" parameter in textarea/index.php when the "event" parameter is set to "article" ("Write" page in admin console) 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 context of an affected site when a malicious article is viewed.

Successful exploitation requires publisher privileges.

3) Input passed as the comment name is not properly sanitised in comment previews. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Other issues e.g. changing a password does not require the old password and a parameter value overflow in textarea/index.php have also been reported.

The vulnerabilities are reported in version 4.0.5. Prior versions may also be affected.


Solution:
Update to version 4.0.6.
