On November 18, 2020 (local time), Cisco released security advisories fixing vulnerabilities in multiple products. These vulnerabilities include three high-risk ones: CVE-2020-3531, CVE-2020-3586, and CVE-2020-3470.
This is an authentication bypass vulnerability in the REST API of Cisco IoT Field Network Director (FND).
The vulnerability exists because the affected software does not properly authenticate REST API calls. An attacker could exploit this vulnerability by obtaining a cross-site request forgery (CSRF) token and then using the token with REST API requests. A successful exploit could allow the attacker to access the back-end database of the affected device and read, alter, or drop information.
- Affected Versions
Cisco IoT FND < 4.6.1
A vulnerability in the web-based management interface of Cisco DNA Spaces Connector could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device.
The vulnerability is due to insufficient validation of user-supplied input in the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on the underling operating system with privileges of the web-based management application.
- Affected Versions
Cisco DNA Spaces Connector <= 2.2
Multiple vulnerabilities in the API subsystem of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges.
The vulnerabilities are due to improper boundary checks for certain user-supplied input. An attacker could exploit these vulnerabilities by sending a crafted HTTP request to the API subsystem of an affected system. A successful exploit could allow the attacker to execute arbitrary code with root privileges on the underlying operating system (OS).
- Affected Versions
5000 Series Enterprise Network Compute System (ENCS) Platforms
UCS C-Series Rack Servers in standalone mode
UCS E-Series Servers
UCS S-Series Servers in standalone mode
