Cisco Enterprise Chat and Email Cross-Site Scripting Vulnerabilities

Multiple vulnerabilities in the web-based management interface of Cisco Enterprise Chat and Email could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of the affected software.

The vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface of the affected software. An attacker could exploit these vulnerabilities either by injecting malicious code in a chat window or by sending a crafted link to a user of the interface. In both cases, the attacker must persuade the user to click the crafted link or open the chat window that contains the attacker’s code. 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.

There are no workarounds that address these vulnerabilities.

Cisco Application Policy Infrastructure Controller IPv6 Link-Local Address Vulnerability

A vulnerability in the management interface of Cisco Application
Policy Infrastructure Controller (APIC) software could allow an
unauthenticated, adjacent attacker to gain unauthorized access on an
affected device.

The vulnerability is due to a lack of proper
access control mechanisms for IPv6 link-local connectivity imposed on
the management interface of an affected device. An attacker on the same physical network could
exploit this vulnerability by attempting to connect to the IPv6
link-local address on the affected device. A successful exploit could allow the attacker to
bypass default access control restrictions on an affected device.

There are no workarounds that address this vulnerability.

Cisco Hyperflex Stored Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco HyperFlex software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected system.

The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously 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.

There are no workarounds that address this vulnerability.

Cisco Webex Teams for iOS Arbitrary File Upload Vulnerability

A vulnerability in the client application for iOS of Cisco Webex Teams could allow an authenticated, remote attacker to upload arbitrary files within the scope of the iOS application.

The vulnerability is due to improper input validation in the client application. An attacker could exploit this vulnerability by sending a malicious file to a targeted user and persuading the user to manually open it. An exploit could allow the attacker to overwrite sensitive application files and eventually cause a denial of service (DoS) condition by foreclosing future access to the system to the targeted user.

There are no workarounds that address this vulnerability.
