Cisco Common Services Platform Collector Stored Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Common Services Platform Collector (CSPC) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.

This vulnerability is due to insufficient validation of user-supplied input that is processed by the web-based management interface. An attacker could exploit this vulnerability by adding malicious code to the configuration by using the web-based management interface. A successful exploit could allow the attacker to execute arbitrary code in the context of the interface or access sensitive, browser-based information.

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

Cisco Common Services Platform Collector SQL Injection Vulnerability

A vulnerability in the configuration dashboard of Cisco Common Services Platform Collector (CSPC) could allow an authenticated, remote attacker to submit a SQL query through the CSPC configuration dashboard.

This vulnerability is due to insufficient input validation of uploaded files. An attacker could exploit this vulnerability by uploading a file containing a SQL query to the configuration dashboard. A successful exploit could allow the attacker to read restricted information from the CSPC SQL database.

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

Cisco Small Business 200, 300, and 500 Series Switches Web-Based Management Interface Denial of Service Vulnerability

A vulnerability in the web-based management interface of Cisco Small Business 200 Series Smart Switches, Cisco Small Business 300 Series Managed Switches, and Cisco Small Business 500 Series Stackable Managed Switches could allow an unauthenticated, remote attacker to render the web-based management interface unusable, resulting in a denial of service (DoS) condition.

This vulnerability is due to improper validation of HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to cause a permanent invalid redirect for requests sent to the web-based management interface of the device, resulting in a DoS condition.

There are no workarounds that address this vulnerability.

Cisco Small Business Series Switches Session Credentials Replay Vulnerability

A vulnerability in the web-based management interface of multiple Cisco Small Business Series Switches could allow an unauthenticated, remote attacker to replay valid user session credentials and gain unauthorized access to the web-based management interface of an affected device.

This vulnerability is due to insufficient expiration of session credentials. An attacker could exploit this vulnerability by conducting a man-in-the-middle attack against an affected device to intercept valid session credentials and then replaying the intercepted credentials toward the same device at a later time. A successful exploit could allow the attacker to access the web-based management interface with administrator privileges.

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

Cisco Small Business RV Series Routers Command Injection Vulnerability

A vulnerability in the web-based management interface of certain Cisco Small Business RV Series Routers could allow an authenticated, remote attacker with administrative privileges to inject arbitrary commands into the underlying operating system and execute them using root-level privileges.

This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending malicious input to a specific field in the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system as a user with root-level privileges.

There are no workarounds that address this vulnerability.

Cisco Prime Infrastructure and Evolved Programmable Network Manager Stored Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Prime Infrastructure (PI) and Cisco Evolved Programmable Network Manager (EPNM) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.

This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

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

Cisco Unified Communications Products Path Traversal Vulnerability

A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P), and Cisco Unity Connection could allow an authenticated, remote attacker to access sensitive data on an affected device.

This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system.

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

Cisco Common Services Platform Collector Information Disclosure Vulnerability

A vulnerability in the web-based management interface of Cisco Common Services Platform Collector (CSPC) could allow an authenticated, remote attacker to access sensitive data on an affected system.

This vulnerability exists because the application does not sufficiently protect sensitive data when responding to a specific API request. An attacker could exploit the vulnerability by sending a crafted HTTP request to the affected application. A successful exploit could allow the attacker to obtain sensitive information about the users of the application, including security questions and answers. To exploit this vulnerability an attacker would need valid Administrator credentials.

Cisco expects to release software updates that address this vulnerability. There are no workarounds that address this vulnerability.
