Cacti graph_image.php denial of service
| cacti-graphimage-dos (34747) |  Low Risk |
Description:
Cacti is vulnerable to a denial of service, caused by improper validation of user-supplied input by the graph_image.php script. By sending multiple requests containing a specially-crafted graph_start, graph_end, graph_width, or the graph_height parameter, a remote authenticated attacker could consume all available CPU resources.
