CVE-2015-3974

TITLE

Used in products from multiple vendors EasyIO EasyIO-30P-SF Vulnerabilities that can gain access rights in controller firmware

Trust: 0.8

sources: JVNDB: JVNDB-2015-004971

DESCRIPTION

EasyIO EasyIO-30P-SF controllers with firmware before 0.5.21 and 2.x before 2.0.5.21, as used in Accutrol, Bar-Tech Automation, Infocon/EasyIO, Honeywell Automation India, Johnson Controls, SyxthSENSE, Transformative Wave Technologies, Tridium Asia Pacific, and Tridium Europe products, have a hardcoded password, which makes it easier for remote attackers to obtain access via unspecified vectors. EasyIO EasyIO-30P-SF is prone to a security-bypass vulnerability. A remote attacker may leverage this issue to gain access to the vulnerable device. EasyIO EasyIO-30P-SF is a 32-bit controller product developed by Malaysia EasyIO company and applied in DDC (direct digital control) system. A security vulnerability exists in EasyIO EasyIO-30P-SF controllers using firmware versions prior to 0.5.21 and 2.x versions prior to 2.0.5.21 due to the program's use of hard-coded passwords
