Rockwell Automation FactoryTalk® Services Platform FTSP - Weak Authentication via JWT Validation Bypass

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.

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 FactoryTalk® Service Platform Service Token Vulnerability

A vulnerability exists in Rockwell Automation FactoryTalk® Service Platform that allows a malicious user to obtain the service token and use it for authentication on another FTSP directory. This is due to the lack of digital signing between the FTSP service token and directory.  If exploited, a malicious user could potentially retrieve user information and modify settings without any authentication.

IMPROPER RESTRICTION OF XML EXTERNAL ENTITY REFERENCE CWE-611

A local, authenticated attacker could use an XML External Entity (XXE) attack to exploit weakly configured XML files to access local or remote content. A successful exploit could potentially cause a denial-of-service condition and allow the attacker to arbitrarily read any local file via system-level services.

Rockwell Automation FactoryTalk Services Platform Protection Mechanism Failure

Rockwell Automation FactoryTalk Services Platform v6.11 and earlier, if FactoryTalk Security is enabled and deployed contains a vulnerability that may allow a remote, authenticated attacker to bypass FactoryTalk Security policies based on the computer name. If successfully exploited, this may allow an attacker to have the same privileges as if they were logged on to the client machine.

Untrusted search path vulnerability in the Clean Utility application in Rockwell Automation FactoryTalk Services Platform before 2.71.00 and FactoryTalk View Studio 8.00.00 and earlier allows local users to gain privileges via a Trojan horse DLL in an unspecified directory.

Integer signedness error in RNADiagnostics.dll in Rockwell Automation FactoryTalk Services Platform (FTSP) CPR9, CPR9-SR1, CPR9-SR2, CPR9-SR3, CPR9-SR4, CPR9-SR5, CPR9-SR5.1, and CPR9-SR6 allows remote attackers to cause a denial of service (service outage or RNADiagReceiver.exe daemon crash) via UDP data that specifies a negative integer value.

Integer overflow in RNADiagnostics.dll in Rockwell Automation FactoryTalk Services Platform (FTSP) CPR9, CPR9-SR1, CPR9-SR2, CPR9-SR3, CPR9-SR4, CPR9-SR5, CPR9-SR5.1, and CPR9-SR6 allows remote attackers to cause a denial of service (service outage or RNADiagReceiver.exe daemon crash) via UDP data that specifies a large integer value.

Rockwell Automation FactoryTalk Services Platform Elevated Privileges Vulnerability

Due to inadequate code logic, a previously unauthenticated threat actor could potentially obtain a local Windows OS user token through the FactoryTalk® Services Platform web service and then use the token to log in into FactoryTalk® Services Platform . This vulnerability can only be exploited if the authorized user did not previously log in into the FactoryTalk® Services Platform web service.

Rockwell Automation FactoryTalk® Service Platform Elevated Privileges Vulnerability Through Web Service Functionality

A privilege escalation vulnerability exists in Rockwell Automation FactoryTalk® Service Platform (FTSP). If exploited, a malicious user with basic user group privileges could potentially sign into the software and receive FTSP Administrator Group privileges. A threat actor could potentially read and modify sensitive data, delete data and render the FTSP system unavailable.

In Rockwell Automation all versions of FactoryTalk Diagnostics software, a subsystem of the FactoryTalk Services Platform, FactoryTalk Diagnostics exposes a .NET Remoting endpoint via RNADiagnosticsSrv.exe at TCPtcp/8082, which can insecurely deserialize untrusted data.

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.

In Rockwell Automation FactoryTalk Services Platform, all versions, the redundancy host service (RdcyHost.exe) does not validate supplied identifiers, which could allow an unauthenticated, adjacent attacker to execute remote COM objects with elevated privileges.

In Rockwell Automation FactoryTalk Services Platform 2.90 and earlier, a remote unauthenticated attacker could send numerous crafted packets to service ports resulting in memory consumption that could lead to a partial or complete denial-of-service condition to the affected services.
