Multiple Buffer Overflow vulnerabilities in the Link Layer Discovery Protocol (LLDP) subsystem of Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges on an affected device. Cisco Bug IDs: CSCuo17183, CSCvd73487.

A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain IKEv2 packets. An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device to be processed. A successful exploit could cause an affected device to continuously consume memory and eventually reload, resulting in a DoS condition. Cisco Bug IDs: CSCvf22394.

A vulnerability in the Bidirectional Forwarding Detection (BFD) offload implementation of Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to cause a crash of the iosd process, causing a denial of service (DoS) condition. The vulnerability is due to insufficient error handling when the BFD header in a BFD packet is incomplete. An attacker could exploit this vulnerability by sending a crafted BFD message to or across an affected switch. A successful exploit could allow the attacker to trigger a reload of the system. This vulnerability affects Catalyst 4500 Supervisor Engine 6-E (K5), Catalyst 4500 Supervisor Engine 6L-E (K10), Catalyst 4500 Supervisor Engine 7-E (K10), Catalyst 4500 Supervisor Engine 7L-E (K10), Catalyst 4500E Supervisor Engine 8-E (K10), Catalyst 4500E Supervisor Engine 8L-E (K10), Catalyst 4500E Supervisor Engine 9-E (K10), Catalyst 4500-X Series Switches (K10), Catalyst 4900M Switch (K5), Catalyst 4948E Ethernet Switch (K5). Cisco Bug IDs: CSCvc40729.

Rockwell Automation FactoryTalk® AssetCentre Data Exposure Vulnerability

A data exposure vulnerability exists in all versions prior to V15.00.001 of Rockwell Automation FactoryTalk® AssetCentre. The vulnerability exists due to storing credentials in the configuration file of EventLogAttachmentExtractor, ArchiveExtractor, LogCleanUp, or ArchiveLogCleanUp packages.

Rockwell Automation FactoryTalk® AssetCentre Data Exposure Vulnerability

A data exposure vulnerability exists in all versions prior to V15.00.001 of Rockwell Automation FactoryTalk® AssetCentre. The vulnerability exists due to insecure storage of FactoryTalk® Security user tokens, which could allow a threat actor to steal a token and, impersonate another user.

Rockwell Automation Comms - 1783-NATR Stored Cross-Site Scripting Vulnerability

A Stored Cross-Site Scripting security issue exists in the affected product that could potentially allow a malicious user to view and modify sensitive data or make the webpage unavailable. The vulnerability stems from missing special character filtering and encoding. Successful exploitation requires an attacker to be able to update configuration fields behind admin login.

Rockwell Automation 1783-NATR Cross-Site Request Forgery Vulnerability

A cross-site request forgery security issue exists in the product and version listed. The vulnerability stems from missing CSRF checks on the impacted form. This allows for unintended configuration modification if an attacker can convince a logged in admin to visit a crafted link.

Rockwell Automation FactoryTalk® Linx Network Browser Security Bypass Vulnerability

A security issue exists within the FactoryTalk Linx Network Browser. By modifying the process.env.NODE_ENV to ‘development’, the attacker can disable FTSP token validation. This bypass allows access to create, update, and delete FTLinx drivers.

Rockwell Automation Comms - 1783-NATR Multiple Broken Authentication Vulnerabilities

Multiple Broken Authentication security issues exist in the affected product. The security issues are due to missing authentication checks on critical functions. These could result in potential denial-of-service, admin account takeover, or NAT rule modifications. Devices would no longer be able to communicate through NATR as a result of denial-of-service or NAT rule modifications. NAT rule modification could also result in device communication to incorrect endpoints. Admin account takeover could allow modification of configuration and require physical access to restore.

Rockwell Automation PanelView Plus 7 Performance Series B Authentication Bypass

An authentication bypass security issue exists within FactoryTalk View Machine Edition Web Browser ActiveX control. Exploitation of this vulnerability allows unauthorized access to the PanelView Plus 7 Series B, including access to the file system, retrieval of diagnostic information, event logs, and more.

Rockwell Automation FactoryTalk View Machine Edition Path Traversal

A path traversal security issue exists within FactoryTalk View Machine Edition, allowing unauthenticated attackers on the same network as the device to delete any file within the panels operating system. Exploitation of this vulnerability is dependent on the knowledge of filenames to be deleted.

Cisco is providing an update for the ongoing investigation into observed exploitation of the web UI feature in Cisco IOS XE Software. We are updating the list of fixed releases and adding the Software Checker. Our investigation has determined that the actors exploited two previously unknown issues. The attacker first exploited CVE-2023-20198 to gain initial access and issued a privilege 15 command to create a local user and password combination. This allowed the user to log in with normal user access. The attacker then exploited another component of the web UI feature, leveraging the new local user to elevate privilege to root and write the implant to the file system. Cisco has assigned CVE-2023-20273 to this issue. CVE-2023-20198 has been assigned a CVSS Score of 10.0. CVE-2023-20273 has been assigned a CVSS Score of 7.2. Both of these CVEs are being tracked by CSCwh87343.

Rockwell Automation Input Validation Vulnerability exists in the SequenceManager™ Server

An input validation vulnerability exists in the Rockwell Automation Sequence Manager™ which could allow a malicious user to send malformed packets to the server and cause a denial-of-service condition. If exploited, the device would become unresponsive, and a manual restart will be required for recovery. Additionally, if exploited, there could be a loss of view for the downstream equipment sequences in the controller. Users would not be able to view the status or command the equipment sequences, however the equipment sequence would continue to execute uninterrupted.
