Successful exploitation of these vulnerabilities could allow an attacker to execute code, crash the device, or view protected data.
The following versions of Crimson, windows configuration software, are affected:
Multiple vulnerabilities can be exploited when a valid user opens a specially crafted, malicious input file that can reference memory after it has been freed.
CVE-2019-10996 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Multiple vulnerabilities can be exploited when a valid user opens a specially crafted, malicious input file that operates outside of the designated memory area.
CVE-2019-10978 has been assigned to this vulnerability. A CVSS v3 base score of 3.3 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).
Multiple vulnerabilities can be exploited when a valid user opens a specially crafted, malicious input file that causes the program to mishandle pointers.
CVE-2019-10984 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Crimson uses a hard-coded password to encrypt protected files in transit and at rest, which may allow an attacker to access configuration files.
CVE-2019-10990 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N).
Michael DePlante, Anthony Fuller, and Todd Manning of Trend Microβs Zero Day Initiative reported these vulnerabilities to CISA.
Red Lion Controls recommends users migrate to Crimson 3.1 release 3112.00 or later where the model choice allows. Updated software can be found at the following link:

CISA recommends users take the following measures to protect themselves from social engineering attacks:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.gov in the Technical Information Paper, ICS-TIP-12-146-01BβTargeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
