CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as problematic, was found in WEKA INTEREST Security Scanner up to 1.8 (Security Testing Software). This affects an unknown code of the component LAN Viewer. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability.

The bug was discovered 07/30/2007. The weakness was presented 06/05/2017 by Marc Ruef with scip AG as ID 101969 as confirmed entry (VulDB). The advisory is shared at vuldb.com. The public release happened without involvement of WEKA. The entry contains:

The Attack Tool Kit (ATK) is an exploiting framwork published under GPL3. Back in 2006 there was a legal dispute between the developer Marc Ruef and the German company WEKA. Ruef claimed that WEKA violated the open-source license while they were using parts of the project within their commercial vulnerability scanner. During the technical analysis of INTEREST SEcurity Scanner several security issues, which affect the handling of the vulnerability scanner, got determined.

This vulnerability is uniquely identified as CVE-2017-20015. The exploitability is told to be easy. An attack has to be approached locally. A authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details are unknown but a public exploit is available. The advisory points out:

If an user is clicking something during the discovery mode, the whole application crashes.

A public exploit has been developed by Marc Ruef and been published immediately after the advisory. The exploit is shared for download at vuldb.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 3598 days. During that time the estimated underground price was around $0-$5k.

The problem might be mitigated by replacing the product with ATK - Attack Tool Kit as an alternative.
