James Bercegay has reported some vulnerabilities in Geeklog, which can be exploited by malicious people to conduct SQL injection attacks, disclose potentially sensitive information and potentially to compromise a vulnerable system.

1) Input passed in cookies to users.php and lib-sessions.php isn't properly sanitised before being used in a SQL query. This can be exploited by manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed in cookies to lib-common.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources. This can be exploited with vulnerability #1 to execute arbitrary PHP code by injecting the code into the "error.log" SQL error log and including it.

The vulnerabilities have been reported in versions prior to 1.3.11sr4 and 1.4.0sr1.
