Multiple vulnerabilities have been discovered in phpGroupWare, which can be exploited by malicious users to disclose sensitive information and by malicious people to disclose sensitive information or conduct cross-site scripting and SQL injection attacks.
1) Input passed to the "csvfile" parameter is not properly verified before being used in addressbook/csv_import.php. This can be exploited to disclose the content of arbitrary files on an affected system.
2) Input passed to the "passwd" parameter in login.php is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
3) Input passed via query parameter names that start with "phpgw_" is not properly sanitised before being returned to the user in login.php. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
4) Input passed via the "conv_type" parameter in addressbook/inc/class.uiXport.inc.php is not properly sanitised before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks.
The vulnerabilities are confirmed in version 0.9.16.12. Other versions may also be affected.
Solution: Reportedly fixed in version 0.9.16.015.
