Studio 5000 Logix Designer 30.01.00 contains an unquoted service path vulnerability in the FactoryTalk Activation Service that allows local users to potentially execute code with elevated privileges. Attackers can exploit the unquoted path in C:\Program Files (x86)\Rockwell Software\FactoryTalk Activation\ to inject malicious code that would execute with LocalSystem permissions.

Products that use EDS Subsystem: Version 28.0.1 and prior (FactoryTalk Linx software (Previously called RSLinx Enterprise): Versions 6.00, 6.10, and 6.11, RSLinx Classic: Version 4.11.00 and prior, RSNetWorx software: Version 28.00.00 and prior, Studio 5000 Logix Designer software: Version 32 and prior) is vulnerable.The EDS subsystem does not provide adequate input sanitation, which may allow an attacker to craft specialized EDS files to inject SQL queries and manipulate the database storing the EDS files. This can lead to denial-of-service conditions.

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 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.

Products that use EDS Subsystem: Version 28.0.1 and prior (FactoryTalk Linx software (Previously called RSLinx Enterprise): Versions 6.00, 6.10, and 6.11, RSLinx Classic: Version 4.11.00 and prior, RSNetWorx software: Version 28.00.00 and prior, Studio 5000 Logix Designer software: Version 32 and prior) is vulnerable. A memory corruption vulnerability exists in the algorithm that matches square brackets in the EDS subsystem. This may allow an attacker to craft specialized EDS files to crash the EDSParser COM object, leading to denial-of-service conditions.

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.

Rockwell Automation Logix Designer Studio 5000 Versions 32.00, 32.01, and 32.02 vulnerable to an xml external entity (XXE) vulnerability, which may allow an attacker to view hostnames or other resources from the program.

A vulnerability uncovered by Team82 and publicly disclosed in 2021 affecting Rockwell Automation's Studio 5000 Logix Designer software and a number of its Logix line of PLCs is under active exploitation. The news surfaced after CISA added CVE-2021-22681 to its Known Exploited Vulnerabilities KEV catalog. Exploits could allow an attacker to bypass verification mechanisms and connect directly to Logix controllers. No further info is available about the attacks involving this CVE. At the time, Rockwell cautioned that the vulnerability could not be remediated with a patch, and the manufacturer recommended a number of mitigations. This is a severe vulnerability and was assessed a 10.0 CVSS v3 score.
