Zikula 1.2.4 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by themes/voodoodolly/version.php and certain other files.

Zikula before 1.3.1 uses the rand and srand PHP functions for random number generation, which makes it easier for remote attackers to defeat protection mechanisms based on randomization by predicting a return value, as demonstrated by the authid protection mechanism.
