Cisco RV340/RV340W/RV345/RV345P Web-based Management Interface deserialization
|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 was found in Cisco RV340, RV340W, RV345 and RV345P (Router Operating System) (the affected version unknown). It has been classified as critical. This affects an unknown functionality of the component Web-based Management Interface. The manipulation with an unknown input leads to a privilege escalation vulnerability. CWE is classifying the issue as CWE-502. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
Multiple vulnerabilities in the web-based management interface of Cisco RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an authenticated, remote attacker to execute arbitrary code with elevated privileges equivalent to the web service process on an affected device. These vulnerabilities exist because HTTP requests are not properly validated. An attacker could exploit these vulnerabilities by sending a crafted HTTP request to the web-based management interface of an affected device. A successful exploit could allow the attacker to remotely execute arbitrary code on the device.
The weakness was published 04/08/2021 as cisco-sa-sb-rv34x-rce-8bfG2h6b. It is possible to read the advisory at tools.cisco.com. This vulnerability is uniquely identified as CVE-2021-1415 since 11/13/2020. The exploitability is told to be easy. It is possible to initiate the attack remotely. The successful exploitation needs a authentication. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/11/2021).
