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 TelescopeJS up to 0.14. This affects an unknown functionality of the component Websocket Message Handler. The manipulation with an unknown input leads to a information disclosure vulnerability (Password). CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on integrity. The summary by CVE is:

TelescopeJS before 0.15 leaks user bcrypt password hashes in websocket messages, which might allow remote attackers to obtain password hashes via a cross-site scripting attack.

The bug was discovered 03/21/2015. The weakness was shared 09/06/2017 by Shubham Shah (oss-sec). The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2015-3454 since 04/29/2015. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 900 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 0.15 eliminates this vulnerability. It is possible to mitigate the problem by adding an authentication mechanism. The best possible mitigation is suggested to be adding authentication.

The vulnerability is also documented in the vulnerability database at SecurityFocus (BID 74331†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
