TITLE

Siemens Automation License Manager Buffer Overflow and Denial of Service Vulnerabilities

Trust: 0.9

sources: BID: 50830 // CNNVD: CNNVD-201111-482

DESCRIPTION

Siemens Automation License Manager (ALM) 4.0 through 5.1+SP1+Upd1 does not properly copy fields obtained from clients, which allows remote attackers to cause a denial of service (exception and daemon crash) via long fields, as demonstrated by fields to the (1) open_session->workstation->NAME or (2) grant->VERSION function. The Siemens Automation License Manager is the authorization manager program for Siemens software. Some long fields can be used to trigger exceptions: The exception unknown software exception (0xc0000417) occurred in the application at location 0x????????. This exception is due to some functions using wcscpy_s to copy the value provided by the client to Caused by the stack buffer. The get_target_ocx_param and send_target_ocx_param commands have a null pointer reference error that can cause the service to crash. Remote attackers can exploit these issues to execute arbitrary code in the context of the application or cause denial-of-service conditions. This vulnerability has been confirmed in (1) open_session->workstation->NAME or (2) grant->VERSION function
