Nazgul Nostromo up to 1.9.3 path traversal

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.

Detailsinfo

A vulnerability, which was classified as critical, was found in Nazgul Nostromo. This affects an unknown function. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Directory traversal vulnerability in nhttpd (aka Nostromo webserver) before 1.9.4 allows remote attackers to execute arbitrary programs or read arbitrary files via a ..%2f (encoded dot dot slash) in a URI.

The bug was discovered 01/12/2011. The weakness was disclosed 03/15/2011 by RedTeam Pentesting with RedTeam Pentesting GmbH (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is uniquely identified as CVE-2011-0751 since 02/02/2011. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available. The attack technique deployed by this issue is T1006 according to MITRE ATT&CK.

A public exploit has been developed in Shell File and been published immediately after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 50 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 1.8.6 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.
