Description:
Hanno Boeck has discovered two vulnerabilities in Serendipity, which can be exploited by malicious users to conduct cross-site scripting and script insertion attacks.
1) Input passed to the "realname" parameter in serendipity_admin.php is not properly sanitised before being stored. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.
2) The serendipity_admin.php script fails to completely validate the extension of an uploaded file. This can be exploited to upload files with the ".html" extension, which can then be used for cross-site scripting attacks.
Successful exploitation of both vulnerabilities requires valid user credentials.
The vulnerabilities are confirmed in version 1.2.1. Other versions may also be affected.
