Description

This security bulletin contains information about 12 secuirty vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2020-3348)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in the web-based management interface. A remote authenticated attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


2) Cross-site scripting (CVE-ID: CVE-2020-3349)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in the web-based management interface. A remote authenticated attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-3380)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to insufficient restrictions during the execution of an affected CLI command. A local user can submit malicious input to a specific command, elevate privileges to root and execute arbitrary commands on the underlying operating system.


4) Missing Authentication for Critical Function (CVE-ID: CVE-2020-3376)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to a failure in the software to perform proper authentication. A remote attacker can brows to one of the hosted URLs in Cisco DCNM, interact with and use certain functions within the Cisco DCNM, leading to authentication bypass and execution of arbitrary actions.


5) Use of hard-coded credentials (CVE-ID: CVE-2020-3382)

The vulnerability allows a remote attacker to gain full access to vulnerable system.

The vulnerability exists due to different installations share a static encryption key. A remote unauthenticated attacker can use the static key to craft a valid session token and access the affected system using the hard-coded credentials.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


6) Improper Authorization (CVE-ID: CVE-2020-3386)

The vulnerability allows a remote attacker to bypass authorization checks.

The vulnerability exists due to insufficient authorization of certain API functions. A remote authenticated attacker can send a specially crafted request and perform arbitrary actions through the REST API with administrative privileges.


7) Missing Authentication for Critical Function (CVE-ID: CVE-2020-3461)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to missing authentication on a specific part of the web-based management interface. A remote attacker can send a specially crafted request and read confidential information from the target device.


8) Path traversal (CVE-ID: CVE-2020-3383)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences within archive files. A remote authenticated attacker can send a specially crafted HTTP request and write arbitrary files in the system with the privileges of the logged-in user.


9) OS Command Injection (CVE-ID: CVE-2020-3384)

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation in specific REST API endpoints. A remote authenticated attacker can send a specially crafted request and execute arbitrary OS commands on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


10) SQL injection (CVE-ID: CVE-2020-3462)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in the web-based management interface. A remote authenticated attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.


11) OS Command Injection (CVE-ID: CVE-2020-3377)

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation in the Device Manager application. A remote authenticated attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


12) Cross-site scripting (CVE-ID: CVE-2020-3460)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in the web-based management interface. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
