A denial-of-service security issue exists in the affected products. The security issue stems from improper handling of exceptional conditions when processing crafted CIP packets sent to the adapter. A power cycle is required to recover the module and associated I/O.

A code execution security issue exists within Studio 5000 Logix Designer® due to an unquoted search path in the External Tools configuration. The executable paths specified in the external tools configuration file are not properly quoted, and because these paths contain spaces, the operating system may resolve them to unintended executables placed earlier in the search order. If exploited, an attacker could plant a malicious executable in a location within the search path, resulting in arbitrary code execution with the same permissions of the user running the application.

A security issue exists within CompactLogix® 5380, ControlLogix® 5580, and EN4 communication modules related to CIP Security certificate revocation handling. The security issue stems from the controller failing to properly reject certificates signed by an intermediate certificate that has been revoked via a Certificate Revocation List (CRL). This could allow a network-based attacker to establish a connection using a certificate that should be untrusted, potentially bypassing CIP Security protections.

A remote code execution security issue exists within Studio 5000 Logix Designer® due to incorrect authorization on a configuration file. This can allow any authenticated user to modify the paths of external tools configured within the application. If exploited, an attacker could alter the configuration to point to a malicious executable, resulting in arbitrary code execution when any user interacts with the external tools functionality.

A path traversal security issue exists within Studio 5000 Logix Designer® due to improper limitation of file paths within ACD project files. The software does not sanitize or validate file names embedded in the ACD file structure during the project opening procedure, allowing path traversal sequences to escape the intended extraction directory. If exploited, an attacker could craft a malicious ACD project file that results in arbitrary files being written to attacker-controlled locations on the file system, potentially leading to code execution.

A path traversal security issue exists within Rockwell Automation ThinManager® software due to improper limitation of file save operations within the API. An authenticated attacker could exploit this vulnerability to write arbitrary files to restricted system directories outside of the application's intended directory.

A security issue exists within FactoryTalk® Services Platform (FTSP), allowing an attacker to bypass JWT signature validation during Okta Web Authentication. The vulnerability stems from the application not verifying that the JWT algorithm is configured for RSA, enabling an attacker to set the algorithm to "none" and craft forged tokens. This could allow an authenticated low-privilege user to impersonate any authorized user on the FTSP server, resulting in unauthorized access to system configuration and the ability to grant permissions to other systems protected by FTSP.

A denial-of-service security issue exists across all the 1756-EN2, EN3, and ENBT communication module due to improper validation of CIP Implicit Connection packets. An attacker on the network can exploit this by sending crafted packets to continuously disrupt device connections, though device connections will recover immediately after.

A security issue exists within the 1715-AENTR EtherNet/IP Adapter. The affected product exposes a network-accessible debug port that does not enforce proper privilege controls, allowing unauthenticated remote access to intrusive command-line interface (CLI) commands. If exploited, a threat actor could read or delete files, stop tasks, modify memory, and change I/O states, potentially impacting the confidentiality, integrity, and availability of the device.

A security issue exists within Arena® Simulation due to a memory corruption vulnerability in the siman.exe (Siman) component. The vulnerability stems from improper validation of user-supplied data, which can result in an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process by convincing a user to open a malicious file.

A security issue exists within Arena® Simulation due to a memory corruption vulnerability in the model.exe (Siman) component. The vulnerability stems from improper validation of user-supplied data, which can result in an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process by convincing a user to open a malicious file.

An improper authentication security issue exists within the 1794-AENTR adapter's embedded web server. The vulnerability allows an unauthenticated attacker to change the device's web interface password by sending a crafted HTTP GET request to a specific endpoint, without any prior authentication being required. If exploited, this could lead to unauthorized access, account takeover, and loss of the device’s embedded web server’s availability.

A denial-of-service security issue exists within the 1794-AENTR adapter due to improper memory handling of CIP protocol requests. This vulnerability can result in the adapter faulting and losing connection to its associated I/O modules, requiring a manual reset to recover.

A security issue was identified in Pavilion due to improper authorization enforcement in API endpoints. This vulnerability can allow an unauthorized actor to execute privileged operations, including user/role management and other administrative actions.

An authentication bypass security issue exists within FactoryTalk Historian Site Edition. By continually sending requests to the login endpoint, an attacker may obtain a valid authentication token.

A sensitive information disclosure security issue exists within the affected CompactLogix controllers. The controller's web server exposes CIP Connection IDs on the diagnostics webpage, which are accessible to any unauthenticated user on the network. This information can be leveraged by an attacker to construct malicious packets, leading to Denial-of-Service.

A security issue exists within 1769 CompactLogix controllers due to the missing validation of sequence numbers and source IP addresses in the CIP protocol. This allows attacker to abuse the exposed Connection ID’s visible on the web interface to perform denial-of-service attacks, resulting in a minor fault.

A denial of service security issue exists in the affected product. The security issue stems from a fault occurring when a crafted CIP message is sent. Devices with less memory are more likely to be affected. This can result in a major nonrecoverable fault (MNRF). A program download is required to recover.
