IDenticard released a software update to mitigate multiple vulnerabilities in its PremiSys access control systems, according to NCCIC.
The vulnerabilities are a use of hard-coded credentials, use of hard-coded password, and an inadequate encryption strength.
Successful exploitation of these remotely exploitable vulnerabilities could allow an attacker to view sensitive information via backups, obtain access to credentials, and/or obtain full access to the system with admin privileges.
Vulnerability details have been publicly disclosed.
An access control system, PremiSys all versions prior to 4.1 suffer from the vulnerabilities, discovered by Jimi Sebree working with Tenable.
In one vulnerability, the system contains hard-coded credentials that allow admin access to the entire service via the PremiSys WCF Service endpoint, which may allow complete control with admin privileges.
CVE-2019-3906 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 8.8.
In addition, the system stores user credentials and other sensitive information with a known weak encryption method, which may allow decryption and exposure of sensitive data.
CVE-2019-3907 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.
Also, the system stores backup files as encrypted zip files. The password to the zip is hard-coded and unchangeable, which may allow access to the information they contain.
CVE-2019-3908 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.
The product sees use in the commercial facilities, government facilities, healthcare and public health, and water and wastewater systems sectors. It also sees action on a global basis.
An attacker with low skill level could leverage the vulnerabilities.
IDenticard released updated software, Version 4.1, to address the hard-coded credential vulnerability (CVE-2019-3906). Inadequate encryption strength (CVE-2019-3907) and use of hard-coded password (CVE-2019-3908) are in process of being fixed with an update expected in February. These software updates will be provided free of charge. Additional information can be obtained by contacting the IDenticard Technical Support Team at (800) 220-8096.
IDenticard also recommends users change the Service Database default username and password.
