The web interface of the 1734-AENTR communication module is vulnerable to stored XSS. A remote, unauthenticated attacker could store a malicious script within the web interface that, when executed, could modify some string values on the homepage of the web interface.
The web interface of the 1734-AENTR communication module mishandles authentication for HTTP POST requests. A remote, unauthenticated attacker can send a crafted request that may allow for modification of the configuration settings.
Rockwell Automation MicroLogix 1100, all versions, allows a remote, unauthenticated attacker sending specially crafted commands to cause the PLC to fault when the controller is switched to RUN mode, which results in a denial-of-service condition. If successfully exploited, this vulnerability will cause the controller to fault whenever the controller is switched to RUN mode.
When an authenticated password change request takes place, this vulnerability could allow the attacker to intercept the message that includes the legitimate, new password hash and replace it with an illegitimate hash. The user would no longer be able to authenticate to the controller (Micro800: All versions, MicroLogix 1400: Version 21 and later) causing a denial-of-service condition
Rockwell Automation MicroLogix 1400 Version 21.6 and below may allow a remote unauthenticated attacker to send a specially crafted Modbus packet allowing the attacker to retrieve or modify random values in the register. If successfully exploited, this may lead to a buffer overflow resulting in a denial-of-service condition. The FAULT LED will flash RED and communications may be lost. Recovery from denial-of-service condition requires the fault to be cleared by the user.
In Rockwell Automation FactoryTalk Services Platform Versions 6.10.00 and 6.11.00, there is an issue with the implementation of the SHA-256 hashing algorithm with FactoryTalk Services Platform that prevents the user password from being hashed properly.
Rockwell Automation DriveTools SP v5.13 and below and Drives AOP v4.12 and below both contain a vulnerability that a local attacker with limited privileges may be able to exploit resulting in privilege escalation and complete control of the system.
An exploitable denial of service vulnerability exists in the ENIP Request Path Network Segment functionality of Allen-Bradley Flex IO 1794-AENT/B 4.003. A specially crafted network request can cause a loss of communications with the device resulting in denial-of-service. An attacker can send a malicious packet to trigger this vulnerability.
KEPServerEX: v6.0 to v6.9, ThingWorx Kepware Server: v6.8 and v6.9, ThingWorx Industrial Connectivity: All versions, OPC-Aggregator: All versions, Rockwell Automation KEPServer Enterprise, GE Digital Industrial Gateway Server: v7.68.804 and v7.66, Software Toolbox TOP Server: All 6.x versions, are vulnerable to a heap-based buffer overflow. Opening a specifically crafted OPC UA message could allow an attacker to crash the server and potentially leak data.
