Cisco SD-WAN Solution Buffer Overflow Vulnerability

A vulnerability in the vContainer of the Cisco SD-WAN Solution could allow an authenticated, remote attacker to cause a denial of service (DoS) condition and execute arbitrary code as the root user.

The vulnerability is due to improper bounds checking by the vContainer. An attacker could exploit this vulnerability by sending a malicious file to an affected vContainer instance. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected vContainer, which could result in a DoS condition that the attacker could use to execute arbitrary code as the root user.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Webex Teams URI Handler Insecure Library Loading Vulnerability

A vulnerability in the Cisco Webex Teams client, formerly Cisco Spark, could allow an attacker to execute arbitrary commands on a targeted system.

This vulnerability is due to unsafe search paths used by the application URI that is defined in Windows operating systems. An attacker could exploit this vulnerability by convincing a targeted user to follow a malicious link. Successful exploitation could cause the application to load libraries from the directory targeted by the URI link. The attacker could use this behavior to execute arbitrary commands on the system with the privileges of the targeted user if the attacker can place a crafted library in a directory that is accessible to the vulnerable system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Connected Mobile Experiences Information Disclosure Vulnerability

A vulnerability in the Cisco Connected Mobile Experiences (CMX) software could allow an unauthenticated, adjacent attacker to access sensitive data on an affected device.

The vulnerability is due to a lack of input and validation checking mechanisms for certain GET requests to API’s on an affected device. An attacker could exploit this vulnerability by sending HTTP GET requests to an affected device. An exploit could allow the attacker to use this information to conduct additional reconnaissance attacks.

There are no workarounds that address this vulnerability.

Cisco Identity Services Engine Privilege Escalation Vulnerability

A vulnerability in the administrative web interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to gain additional privileges on an affected device.

The vulnerability is due to improper controls on certain pages in the web interface. An attacker could exploit this vulnerability by authenticating to the device with an administrator account and sending a crafted HTTP request. A successful exploit could allow the attacker to create additional Admin accounts with different user roles. An attacker could then use these accounts to perform actions within their scope. The attacker would need valid Admin credentials for the device. This vulnerability cannot be exploited to add a Super Admin account.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Multiple Privilege Escalation Vulnerabilities in Cisco SD-WAN Solution

Multiple vulnerabilities in the local CLI of the Cisco SD-WAN Solution could allow an authenticated, local attacker to escalate privileges and modify device configuration files.

The vulnerabilities exist because user input is not properly sanitized for certain commands at the CLI. An attacker could exploit these vulnerabilities by sending crafted commands to the CLI of an affected device. A successful exploit could allow the attacker to establish an interactive session with elevated privileges. The attacker could then use the elevated privileges to further compromise the device or obtain additional configuration data from the device.

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

Cisco SD-WAN Solution Arbitrary File Overwrite Vulnerability

A vulnerability in the Cisco SD-WAN Solution could allow an authenticated, remote attacker to overwrite arbitrary files on the underlying operating system of an affected device.

The vulnerability is due to improper input validation of the save command in the CLI of the affected software. An attacker could exploit this vulnerability by modifying the save command in the CLI of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the underlying operating system of an affected device and escalate their privileges to the root user.

Cisco Unified Intelligence Center Cross-Site Request Forgery Vulnerability

A vulnerability in the web-based management interface of Cisco Unified Intelligence Center could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device.

The vulnerability is due to insufficient CSRF protections in the web-based management interface. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious, customized link. A successful exploit could allow the attacker to perform arbitrary actions on the affected device via a web browser and with the privileges of the user.

There are no workarounds that address this vulnerability.
