PHP remote file inclusion vulnerability in games.php in MyCMS 0.9.8 and earlier allows remote attackers to execute arbitrary PHP code via a URL in the id parameter.

Multiple direct static code injection vulnerabilities in MyCMS 0.9.8 and earlier allow remote attackers to inject arbitrary PHP code into (1) a _score.txt file via the score parameter, or (2) a _setby.txt file via a login cookie, which is then included by games.php. NOTE: programs that use games.php might include (a) snakep.php, (b) tetrisp.php, and possibly other site-specific files.

MyCMS 0.9.8 and earlier allows remote attackers to gain privileges via the admin cookie parameter, as demonstrated by a post to admin/settings.php that injects PHP code into settings.inc, which can then be executed via a direct request to index.php.
