Detailsinfo

A vulnerability, which was classified as critical, has been found in LOYTEC LVIS-3ME up to 6.1.x. This issue affects an unknown code block of the component Random Number Generator. The manipulation with an unknown input leads to a entropy vulnerability. Using CWE to declare the problem leads to CWE-331. The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An Insufficient Entropy issue was discovered in LOYTEC LVIS-3ME versions prior to 6.2.0. The application does not utilize sufficiently random number generation for the web interface authentication mechanism, which could allow remote code execution.

The bug was discovered 09/14/2017. The weakness was published 10/05/2017 (Website). The advisory is shared at securityfocus.com. The identification of this vulnerability is CVE-2017-13992 since 08/30/2017. The attack may be initiated remotely. The requirement for exploitation is a simple authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 21 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 6.2.0 eliminates this vulnerability.
