[-] Affected Versions:

All versions from 9.0.0-RC1 to 14.0.0-RC4.


[-] Vulnerability Description:

The vulnerability is located in the
/template/scripts/BxBaseMenuSetAclLevel.php script. Specifically,
within the BxBaseMenuSetAclLevel::getCode() method. When calling this
method, user input passed through the "profile_id" POST parameter is
not properly sanitized before being used in a call to the
unserialize() PHP function. This can be exploited by remote,
unauthenticated attackers to inject arbitrary PHP objects into the
application scope, allowing them to perform a variety of attacks, such
as writing and executing arbitrary PHP code.
