undefsafe up to 2.0.2 Prototype injection

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 was found in undefsafe up to 2.0.2. It has been classified as critical. Affected is some unknown processing. The manipulation with an unknown input leads to a injection vulnerability (Prototype). CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

undefsafe before 2.0.3 is vulnerable to Prototype Pollution. The 'a' function could be tricked into adding or modifying properties of Object.prototype using a __proto__ payload.

The weakness was shared 02/18/2020. This vulnerability is traded as CVE-2019-10795 since 04/03/2019. The exploitability is told to be easy. It is possible to launch the attack remotely. Required for exploitation is a authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1055.
