Rockwell Automation was made aware that the webservers of the Micrologix 1100 and 1400 controllers contain a vulnerability that may lead to a denial-of-service condition. The security vulnerability could be exploited by an attacker with network access to the affected systems by sending TCP packets to webserver and closing it abruptly which would cause a denial-of-service condition for the web server application on the device

Rockwell Automation was made aware of a vulnerability by a security researcher from Georgia Institute of Technology that the MicroLogix 1100 and 1400 controllers contain a vulnerability that may give an attacker the ability to accomplish remote code execution. The vulnerability is an unauthenticated stored cross-site scripting vulnerability in the embedded webserver. The payload is transferred to the controller over SNMP and is rendered on the homepage of the embedded website.

| The X-Frame-Options header in Rockwell Automation MicroLogix 1100/1400 Versions 21.007 and prior is not configured in the HTTP response, which could allow clickjacking attacks. |
| Cross-site scripting (XSS) vulnerability in the web server on Allen-Bradley MicroLogix 1100 devices before B FRN 15.000 and 1400 devices before B FRN 15.003 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. |
| Allen-Bradley MicroLogix 1100 devices before B FRN 15.000 and 1400 devices before B FRN 15.003 allow remote attackers to cause a denial of service (memory corruption and device crash) via a crafted HTTP request. |
| Stack-based buffer overflow on Allen-Bradley MicroLogix 1100 devices before B FRN 15.000 and 1400 devices through B FRN 15.003 allows remote attackers to execute arbitrary code via unspecified vectors. |
| SQL injection vulnerability on Allen-Bradley MicroLogix 1100 devices before B FRN 15.000 and 1400 devices before B FRN 15.003 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors. |
| Allen-Bradley MicroLogix 1100 devices before B FRN 15.000 and 1400 devices before B FRN 15.003 allow remote authenticated users to insert the content of an arbitrary file into a FRAME element via unspecified vectors. |
| 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. |
| Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior, The cryptographic key utilized to help protect the account password is hard coded into the RSLogix 500 binary file. An attacker could identify cryptographic keys and use it for further cryptographic attacks that could ultimately lead to a remote attacker gaining unauthorized access to the controller. |
| Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior, A remote, unauthenticated attacker can send a request from the RSLogix 500 software to the victim’s MicroLogix controller. The controller will then respond to the client with used password values to authenticate the user on the client-side. This method of authentication may allow an attacker to bypass authentication altogether, disclose sensitive information, or leak credentials. |
| Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior, The cryptographic function utilized to protect the password in MicroLogix is discoverable. |
| Rockwell Automation MicroLogix 1400 Controllers Series B v21.001 and prior, Series A, all versions, MicroLogix 1100 Controller, all versions, RSLogix 500 Software v12.001 and prior, If Simple Mail Transfer Protocol (SMTP) account data is saved in RSLogix 500, a local attacker with access to a victim’s project may be able to gather SMTP server authentication data as it is written to the project file in cleartext. |
| In Rockwell Automation MicroLogix 1400 Controllers Series A, All Versions Series B, v15.002 and earlier, MicroLogix 1100 Controllers v14.00 and earlier, CompactLogix 5370 L1 controllers v30.014 and earlier, CompactLogix 5370 L2 controllers v30.014 and earlier, CompactLogix 5370 L3 controllers (includes CompactLogix GuardLogix controllers) v30.014 and earlier, an open redirect vulnerability could allow a remote unauthenticated attacker to input a malicious link to redirect users to a malicious site that could run or download arbitrary malware on the user’s machine. |
| Rockwell Automation MicroLogix 1400 Controllers and 1756 ControlLogix Communications Modules An unauthenticated, remote threat actor could send a CIP connection request to an affected device, and upon successful connection, send a new IP configuration to the affected device even if the controller in the system is set to Hard RUN mode. When the affected device accepts this new IP configuration, a loss of communication occurs between the device and the rest of the system as the system traffic is still attempting to communicate with the device via the overwritten IP address. |
| An exploitable access control vulnerability exists in the data, program, and function file permissions functionality of Allen Bradley Micrologix 1400 Series B FRN 21.2 and before. A specially crafted packet can cause a read or write operation resulting in disclosure of sensitive information, modification of settings, or modification of ladder logic. An attacker can send unauthenticated packets to trigger this vulnerability. Required Keyswitch State: Any Description: Reads the encoded ladder logic from its data file and print it out in HEX. |
| An exploitable access control vulnerability exists in the data, program, and function file permissions functionality of Allen Bradley Micrologix 1400 Series B FRN 21.2 and before. A specially crafted packet can cause a read or write operation resulting in disclosure of sensitive information, modification of settings, or modification of ladder logic. An attacker can send unauthenticated packets to trigger this vulnerability. Required Keyswitch State: Any Description: Requests a specific set of bytes from an undocumented data file and returns the ASCII version of the master password. |
| An exploitable access control vulnerability exists in the data, program, and function file permissions functionality of Allen Bradley Micrologix 1400 Series B FRN 21.2 and before. A specially crafted packet can cause a read or write operation resulting in disclosure of sensitive information, modification of settings, or modification of ladder logic. An attacker can send unauthenticated packets to trigger this vulnerability. Required Keyswitch State: REMOTE or PROG Associated Fault Codes: 0023, 002e, and 0037 Fault Type: Recoverable Description: The STI, EII, and HSC function files contain bits signifying whether or not a fault has occurred. Additionally there is a bit signaling the module to auto start. When these bits are set for any of the three modules and the device is moved into a run state, a fault is triggered. |

A specially crafted packet can cause a read or write operation resulting in disclosure of sensitive information, modification of settings, or modification of ladder logic. An attacker can send unauthenticated packets to trigger this vulnerability. Required Keyswitch State: REMOTE or PROG or RUN Description: The value 0xffffffff is considered NaN for the Float data type. When a float is set to this value and used in the PLC, a fault is triggered. NOTE: This is not possible through RSLogix. |
