Rockwell Automation Compact GuardLogix® 5370 Denial-Of-Service Vulnerability

A denial-of-service security issue in the affected product. The security issue stems from a fault occurring when a crafted CIP unconnected explicit message is sent. This can result in a major non-recoverable fault.

CompactLogix ®, ControlLogix ®, Compact GuardLogix ® and GuardLogix ® Buffer Overflow

A denial-of-service issue exists in  5370/5570 controllers. This vulnerability could potentially allow a remote user to load an invalid project, causing the device to enter a major non-recoverable fault (MNRF).

CompactLogix ®, ControlLogix ®, Compact GuardLogix ® and GuardLogix ® Buffer Overflow

A denial-of-service issue exists in 5380/5480/5580 controllers. This vulnerability could potentially allow a malicious user to write invalid file data to the controller, causing the device to enter a major non-recoverable fault (MNRF).

Rockwell Automation Studio 5000 Logix Designer Versions 21 and later, and RSLogix 5000 Versions 16 through 20 use a key to verify Logix controllers are communicating with Rockwell Automation CompactLogix 1768, 1769, 5370, 5380, 5480: ControlLogix 5550, 5560, 5570, 5580; DriveLogix 5560, 5730, 1794-L34; Compact GuardLogix 5370, 5380; GuardLogix 5570, 5580; SoftLogix 5800. Rockwell Automation Studio 5000 Logix Designer Versions 21 and later and RSLogix 5000: Versions 16 through 20 are vulnerable because an unauthenticated attacker could bypass this verification mechanism and authenticate with Rockwell Automation CompactLogix 1768, 1769, 5370, 5380, 5480: ControlLogix 5550, 5560, 5570, 5580; DriveLogix 5560, 5730, 1794-L34; Compact GuardLogix 5370, 5380; GuardLogix 5570, 5580; SoftLogix 5800.

Rockwell Automation CompactLogix 5370 Stack-based Buffer Overflow

An attacker could send crafted SMTP packets to cause a denial-of-service condition where the controller enters a major non-recoverable faulted state (MNRF) in CompactLogix 5370 L1, L2, and L3 Controllers, Compact GuardLogix 5370 controllers, and Armor Compact GuardLogix 5370 Controllers Versions 20 - 30 and earlier.

Rockwell Automation CompactLogix 5370 and ControlLogix 5570 Controllers Improper Input Validation

The connection establishment algorithm found in Rockwell Automation CompactLogix 5370 and ControlLogix 5570 versions 33 and prior does not sufficiently manage its control flow during execution, creating an infinite loop. This may allow an attacker to send specially crafted CIP packet requests to a controller, which may cause denial-of-service conditions in communications with other products.

ICSA-22-090-05 Rockwell Automation Logix Controllers

An attacker with the ability to modify a user program may change user program code on some ControlLogix, CompactLogix, and GuardLogix Control systems. Studio 5000 Logix Designer writes user-readable program code to a separate location than the executed compiled code, allowing an attacker to change one and not the other.

Rockwell Automation Logix Controllers Uncontrolled Resource Consumption

A malformed Class 3 common industrial protocol message with a cached connection can cause a denial-of-service condition in Rockwell Automation Logix Controllers, resulting in a major nonrecoverable fault. If the target device becomes unavailable, a user would have to clear the fault and redownload the user project file to bring the device back online.

Rockwell Automation GuardLogix and ControlLogix controllers Vulnerable to Denial-Of-Service Attack

A vulnerability exists in the Rockwell Automation controllers that allows a malformed CIP request to cause a major non-recoverable fault (MNRF) and a denial-of-service condition (DOS).
