|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 critical, was found in Netgear XR1000 22.214.171.124_1.0.38 (Wireless LAN Software). This affects an unknown functionality of the component SOAP Message Handler. The manipulation with an unknown input leads to a weak authentication vulnerability. CWE is classifying the issue as CWE-306. The software does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. This is going to have an impact on confidentiality. The summary by CVE is:
This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of NETGEAR XR1000 126.96.36.199_1.0.38 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of SOAP messages. The issue results from a lack of authentication required for a privileged request. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-13325.
The weakness was disclosed 01/25/2022. The advisory is shared at zerodayinitiative.com. This vulnerability is uniquely identified as CVE-2021-34870 since 06/17/2021.
