SQL injection vulnerability in Mambo 4.5.3, 4.5.3h, and possibly earlier versions allows remote attackers to execute arbitrary SQL commands via (1) the $username variable in the mosGetParam function and (2) the $task parameter in the mosMenuCheck function in (a) includes/mambo.php; and (3) the $filter variable to the showCategory function in the comcontent component (content.php).

DISPUTED PHP remote file inclusion vulnerability in contentpublisher.php in the contentpublisher component (comcontentpublisher) for Mambo allows remote attackers to execute arbitrary PHP code via a URL in the mosConfigabsolutepath parameter. NOTE: this issue has been disputed by third parties who state that contentpublisher.php protects against direct request in the most recent version. The original researcher is known to be frequently inaccurate.

content.php in Mambo 4.5.2 through 4.5.2.3 allows remote attackers to obtain the installation path of the application via a URL that causes the application to return an error.
