CVE-2017-9855

TITLE

plural SMA Solar Technology Vulnerabilities related to authorization, authority, and access control in products

Trust: 0.8

sources: JVNDB: JVNDB-2017-006907

DESCRIPTION

An issue was discovered in SMA Solar Technology products. A secondary authentication system is available for Installers called the Grid Guard system. This system uses predictable codes, and a single Grid Guard code can be used on any SMA inverter. Any such code, when combined with the installer account, allows changing very sensitive parameters. NOTE: the vendor reports that Grid Guard is not an authentication feature; it is only a tracing feature. Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected. ** Unsettled ** This case has not been confirmed as a vulnerability. plural SMA Solar Technology The product contains vulnerabilities related to authorization, permissions, and access control. The vendor has disputed this vulnerability. For details, see NVD of Current Description Please Confirm. https://nvd.nist.gov/vuln/detail/CVE-2017-9855Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. SMASolarTechnologyinverter is a photovoltaic inverter device from SMA Germany. There is a security hole in SMASolarTechnologyinverter. An attacker could exploit this vulnerability to change sensitive parameters
