PDQ Manufacturing, Inc. is working on fixes for improper authentication and missing encryption of sensitive data vulnerabilities in its LaserWash, Laser Jet and ProTouch products, according to a report with ICS-CERT.

Successful exploitation of these remotely exploitable vulnerabilities may allow a remote attacker to gain unauthorized access to the affected system and to issue unexpected commands to impact the intended operation of the system.

An attacker with low skill level would be able to leverage the vulnerabilities. Public exploits are available

The affected web-server does not properly verify that provided authentication information is correct.

CVE-2017-9630 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.4.

In addition, the username and password are transmitted insecurely.

CVE-2017-9632 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

The products see action in the commercial facilities sector. It sees use on a global basis.

De Pere, Wisconsin-based PDQ Manufacturing, Inc. (“PDQ”) has validated the vulnerabilities and is developing product fixes for the affected systems. In the interim, PDQ. has identified compensating controls to limit the exploitability of the affected systems.

PDQ recommends users apply the following controls:
• Always make sure any PDQ equipment is not accessible from the Internet; it should be behind a secure firewall.
• Whenever a machine or router is received and installed, always change the default password from the factory settings to a new password unique to the machine. If an existing site is still using the factory default passwords on a machine or router, immediately change the default password to a new, unique, strong password.
• Always set up the system network (router or Wi-Fi) with its security features enabled such that they require a username and password to be able to access the machine network.
• Do not set up the site router with “port forwarding” enabled. This can effectively expose the system to the Internet and may permit an unauthorized person to reach the machine login screen.
• Do not share passwords or write them down in an accessible place where unauthorized users may find them.
