Critical vulnerability disclosed in DNA sequencing systems
The U.S. Cybersecurity Infrastructure Security Agency (CISA) and the Food and Drug Administration (FDA) have released a disclosure pertaining to two security vulnerabilities that affect Illumina’s Universal Copy Service (UCS), which is used for DNA sequencing in labs and medical facilities.
The first flaw is tracked as CVE-2023-1968 and allows an unauthenticated threat actor to use UCS to listen on all IP addresses, including those capable of accepting remote communications.
The second is tracked as CVE-2023-1966, which relates to a security misconfiguration allowing users of UCS to execute commands with elevated privileges.
Exploitation of these vulnerabilities could allow a threat actor to upload and execute code remotely at the operating system level, which could lead to the modification of settings, configurations, software, or the access of sensitive data on the affected product.
Security updates have been released for vulnerabilities in the affected product versions. As such, previous versions are vulnerable to potential exploit.

Containment, Mitigations & Remediations
The Illumina Advisory contains the relevant remediation instructions for the affected product versions. It is strongly recommended that the associated steps are adhered to as soon as possible.
CISA also recommends that these steps are followed:
– Minimise the exposure of the affected systems to the internet as much as possible
– Utilise firewalls to isolate systems from the wider network
– Utilise VPNs when remote access is required
