Detailsinfo

A vulnerability has been found in WEKA INTEREST Security Scanner up to 1.8 (Security Testing Software) and classified as problematic. This vulnerability affects an unknown code block of the component Portscan. The manipulation with an unknown input leads to a memory allocation vulnerability. The CWE definition for the vulnerability is CWE-789. The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. As an impact it is known to affect availability.

The bug was discovered 07/30/2007. The weakness was shared 06/05/2017 by Marc Ruef with scip AG as ID 101969 as confirmed entry (VulDB). The advisory is available at vuldb.com. The vendor was not involved in the coordination of the public release. 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 was named CVE-2017-20016. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. Technical details are unknown but a public exploit is available. The advisory points out:
After a portscan the software connects to chargen services which will cause a memory exhaustion.

A public exploit has been developed by Marc Ruef and been published immediately after the advisory. It is possible to download the exploit 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. The entry contains the following remark:

A restart of the software is not enough to eliminate this issue. De-installing and re-installing the whole software is required.
