------------------------------------------------------------------------------ SuiteCRM <= 7.11.11 (add_to_prospect_list) Broken Access Control Vulnerability ------------------------------------------------------------------------------ [-] Software Link: https://suitecrm.com/ [-] Affected Versions: Version 7.11.11 and prior versions. [-] Vulnerability Description: There is a Local File Inclusion vulnerability within the "add_to_prospect_list" function. User input passed through the "parent_module" and "parent_type" parameters is not properly validated before being used in a call to the include() function. This can be exploited to include arbitrary .php files within the webroot and potentially bypass authorization mechanisms (for instance, by setting the "parent_module" parameter to "Administration" and the "parent_type" parameter to "expandDatabase" or any other administrative action which does not implement ACL checks). [-] Solution: No official solution is currently available.
