CVSS: 10.0EPSS: 0%CPEs: 9EXPL: 1CVE-2021-34730 – Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34730
A vulnerability in the Universal Plug-and-Play (UPnP) service of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of incoming UPnP traffic. An attacker could exploit this vulnerability by sending a crafted UPnP request to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a DoS condition. Cisco has not released software updates that address this vulnerability. • https://github.com/badmonkey7/CVE-2021-34730 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cisco-sb-rv-overflow-htpymMB5 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-1602
A vulnerability in the web-based management interface of Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers could allow an unauthenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient user input validation. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device using root-level privileges. Due to the nature of the vulnerability, only commands without parameters can be executed. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv-code-execution-9UVJr7k4 • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
