Detailsinfo

A vulnerability was found in Sprecher Automation SPRECON-E Service Program up to 3.42 (Automation Software). It has been declared as critical. This vulnerability affects an unknown part of the file service/maintenance. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in Sprecher Automation SPRECON-E Service Program before 3.43 SP0. Under certain preconditions, it is possible to execute telegram simulation as a non-admin user. As prerequisites, a user must have created an online-connection, validly authenticated and authorized as administrator, and executed telegram simulation. After that, the online-connection must have been closed. Incorrect caching of client data then may lead to privilege escalation, where a subsequently acting non-admin user is permitted to do telegram simulation. In order to exploit this vulnerability, a potential attacker would need to have both a valid engineering-account in the SPRECON RBAC system as well as access to a service/maintenance computer with SPRECON-E Service Program running. Additionally, a valid admin-user must have closed the service connection beforehand without closing the program, having executed telegram simulation; the attacker then has access to the running software instance. Hence, there is no risk from external attackers.

The bug was discovered 12/21/2016. The weakness was presented 12/25/2016 (Website). The advisory is available at sprecher-automation.com. This vulnerability was named CVE-2016-10041 since 12/25/2016.
