TL;DR 📌

A high-severity vulnerability has been identified in the Cisco Catalyst Center, allowing unauthenticated remote attackers to read and modify proxy configuration settings via an unprotected API endpoint. This could disrupt internet traffic or allow interception of outbound traffic. Users are advised to upgrade to fixed software version 2.3.7.9 or later.

What happened 🕵️‍♂️

A vulnerability in the management API of Cisco Catalyst Center (formerly Cisco DNA Center) has been discovered. This issue stems from a lack of authentication on an API endpoint, enabling unauthenticated remote attackers to send requests that could read or modify the outgoing proxy configuration. Such exploitation could disrupt internet traffic or allow attackers to intercept outbound traffic.

TL;DR 📌

A medium-severity vulnerability in the Cisco Webex Meeting Client could allow an unauthenticated attacker on a local network to join meetings as another user. Cisco has addressed this issue, and no user action is required.

What happened 🕵️‍♂️

A vulnerability was identified in the meeting-join functionality of Cisco Webex Meetings. This flaw could permit an unauthenticated, network-proximate attacker to impersonate a legitimate user during the meeting-join process. The vulnerability arises from issues with client certificate validation, allowing an attacker to intercept and complete a meeting-join flow if they are positioned on a local or adjacent network. Cisco has confirmed that there is no known malicious exploitation of this vulnerability.

TL;DR 📌

Multiple stored cross-site scripting (XSS) vulnerabilities have been identified in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC). These vulnerabilities could allow authenticated attackers to modify configurations or execute malicious scripts. Software updates are available to address these issues, but no workarounds exist.

What happened 🕵️‍♂️

Cisco has disclosed multiple vulnerabilities in its Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC). These vulnerabilities could allow an authenticated, remote attacker to conduct stored XSS attacks or modify device configurations. The vulnerabilities stem from insufficient validation of user input and lack of server-side validation of administrator permissions.

TL;DR 📌

Cisco published a security advisory. See the Fixed software table below for the version you should upgrade to.

What happened 🕵️‍♂️

A vulnerability in the application data endpoints of Cisco Catalyst SD-WAN Manager, formerly Cisco SD-WAN vManage, could allow an authenticated, remote attacker to write arbitrary files to an affected system.

This vulnerability is due to improper validation of requests to APIs. An attacker could exploit this vulnerability by sending malicious requests to an API within the affected system. A successful exploit could allow the attacker to conduct directory traversal attacks and write files to an arbitrary location on the affected system.

TL;DR 📌

• Multiple vulnerabilities in the update process of Cisco ThousandEyes Endpoint Agent for Windows could allow an authenticated, local attacker to delete arbitrary files on an affected device. These vulnerabilities are due to improper access controls on files that are in the local file system. An attacker could exploit these vulnerabilities by using a symbolic link to perform an agent upgrade…
