Natus Medical, Inc. (Natus) released a software update to mitigate stack-based buffer overflow and out-of-bounds read vulnerabilities in its Xltek NeuroWorks software, according to a report with NCCIC.

Successful exploitation of these vulnerabilities require access to the Natus customer network, and could crash the device being accessed; a buffer overflow condition may allow remote code execution.

Used in Natus Xltek EEG medical products, Natus Xltek NeuroWorks Version 8 suffers from the remotely exploitable vulnerabilities, discovered by Cory Duplantis from Cisco Talos.

In one vulnerability, a specially-crafted packet may be able to cause an out-of-bounds read, which may result in a denial-of-service condition.

CVE-2017-2852 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

In addition, an attacker may cause a buffer overflow by sending a specially-crafted packet to the affected product while the product attempts to open a file requested by the client.

CVE-2017-2853 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 10.0.

Also, a specially-crafted packet may cause an out-of-bounds read, which may result in a denial-of-service condition.

CVE-2017-2858 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

In addition, a specially-crafted packet may cause an out-of-bounds read, which may result in a denial-of-service condition.

CVE-2017-2860 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

Also, a specially-crafted packet may cause an out-of-bounds read, which may result in a denial-of-service condition.

CVE-2017-2861 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

A specially-crafted packet received during the execution of certain commands can cause memory to be overwritten in a way that could allow an attacker to take control of the program.

CVE-2017-2867 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.0.

In another vulnerability, an error in the way the program parses data structures may allow an attacker to take control of the system by sending it a specially-crafted packet.

CVE-2017-2868 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 10.0.

In addition, a specially-crafted packet takes advantage of the way the program parses data structures and may cause a buffer overflow, which may allow remote execution of arbitrary code.

CVE-2017-2869 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 10.0.

The product sees use mainly in the healthcare and public health sectors on a global basis.

No known public exploits specifically target these vulnerabilities. However, an attacker with low skill level could leverage the vulnerabilities.
