common.inc.php in phpWebLog 0.4.2 does not properly initialize the $CONF array, which inadvertently sets the password to a single character, allowing remote attackers to easily guess the SiteKey and gain administrative privileges to phpWebLog.

PHP remote file inclusion vulnerability in PHPWebLog 0.5.3 and earlier allows remote attackers to execute arbitrary PHP code by modifying the (1) G_PATH parameter to init.inc.php or the (2) PATH parameter to index.php to reference a URL on a remote web server that contains the code.
