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.
The identification of this vulnerability is CVE-2017-20011. The exploitation is known to be easy. An attack has to be approached locally. The successful exploitation requires a simple authentication. 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:
This version does not send a newline twice within HTTP plugins which leads to corrupt HTTP requests. These are not able to determine any issues.

A public exploit has been developed by Marc Ruef and been published immediately after the advisory. The exploit is available at vuldb.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 4265 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.
