Carl Hurd of Cisco Talos discovered these vulnerabilities.
Cisco Talos recently discovered two vulnerabilities in WellinTech’s KingHistorian industrial control systems data manager.
KingHistorian is a time-series database that allows users to ingest and process large amounts of data from ICS, including built-in statistical analysis.
Talos discovered an information disclosure vulnerability (TALOS-2022-1683/CVE-2022-45124) in the software’s user authentication function. If an adversary could capture an authentication packet, it contains all the necessary information to steal the target user’s username and password for the software.
Another vulnerability, TALOS-2022-1674 (CVE-2022-43663) exists in a DLL in the software that could allow an adversary to cause a buffer overflow by sending a malicious packet to the targeted machine.
Cisco Talos worked with WellinTech to ensure that these issues are resolved and an update is available for affected customers, all in adherence to Cisco’s vulnerability disclosure policy.
Users are encouraged to update these affected products as soon as possible: WellinTech KingHistorian, version 35.01.00.05. Talos tested and confirmed these versions of KingHistorian could be exploited by these vulnerabilities.
The following Snort rule will detect exploitation attempts against this vulnerability: 61093. Additional rules may be released in the future and current rules are subject to change, pending additional vulnerability information.
