A CWE-798: Use of Hard-coded Credentials vulnerability exists in the Unity Loader and OS Loader Software (all versions). The fixed credentials are used to simplify file transfer. Today the use of fixed credentials is considered a vulnerability, which could cause unauthorized access to the file transfer service provided by the Modicon PLCs. This could result in various unintended results.

A CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability exists in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD)which could cause arbitrary application execution when the computer starts.

A CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability during zip file extraction exists in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD) which could cause unauthorized write access outside of expected path folder when opening the project file.

A CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability exists in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD) which could cause malicious code execution when opening the project file.

A CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability exists in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD) which could cause malicious code execution when opening the project file.

A CWE-521: Weak Password Requirements vulnerability exists in the GP-Pro EX V1.00 to V4.09.100 which could cause the discovery of the password when the user is entering the password because it is not masqueraded.

**VERSION NOT SUPPORTED WHEN ASSIGNED** A legacy debug port account in TCMs installed in Tricon system versions 10.2.0 through 10.5.3 is visible on the network and could allow inappropriate access. This vulnerability was remediated in TCM version 10.5.4.

A CWE-426: Untrusted Search Path vulnerability exists in Vijeo Designer Basic (V1.1 HotFix 15 and prior) and Vijeo Designer (V6.9 SP9 and prior), which could cause arbitrary code execution on the system running Vijeo Basic when a malicious DLL library is loaded by the Product.

A CWE-345: Insufficient Verification of Data Authenticity vulnerability exists which could allow the attacker to execute malicious code on the Modicon M218, M241, M251, and M258 controllers.

**VERSION NOT SUPPORTED WHEN ASSIGNED** A vulnerability could cause TCM modules to reset when under high network load in TCM v10.4.x and in system v10.3.x. This vulnerability was discovered and remediated in version v10.5.x on August 13, 2009. TCMs from v10.5.x and on will no longer exhibit this behavior.

**VERSION NOT SUPPORTED WHEN ASSIGNED** A legacy support account in the TriStation software version v4.9.0 and earlier could cause improper access to the TriStation host machine. This was addressed in TriStation version v4.9.1 and v4.10.1 released on May 30, 2013.1

**VERSION NOT SUPPORTED WHEN ASSIGNED** A vulnerability with the former 'password' feature could allow a denial of service attack if the user is not following documented guidelines pertaining to dedicated TriStation connection and key-switch protection. This vulnerability was discovered and remediated in versions v4.9.1 and v4.10.1 on May 30, 2013. This feature is not present in version v4.9.1 and v4.10.1 through current. Therefore, the vulnerability is not present in these versions.

**VERSION NOT SUPPORTED WHEN ASSIGNED** A vulnerability could cause certain data to be visible on the network when the 'password' feature is enabled. This vulnerability was discovered in and remediated in versions v4.9.1 and v4.10.1 on May 30, 2013. The 'password' feature is an additional optional check performed by TS1131 that it is connected to a specific controller. This data is sent as clear text and is visible on the network. This feature is not present in TriStation 1131 versions v4.9.1 and v4.10.1 through current. Therefore, the vulnerability is not present in these versions.

A CWE-79:Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability exists Andover Continuum (All versions), which could cause a Reflective Cross-site Scripting (XSS attack) when using the products' web server.

A CWE-79:Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability exists Andover Continuum (All versions), which could enable a successful Cross-site Scripting (XSS attack) when using the products' web server.

A CWE-94: Improper Control of Generation of Code ('Code Injection') vulnerability exists in Andover Continuum (All versions), which could cause files on the application server filesystem to be viewable when an attacker interferes with an application's processing of XML data.

A CWE-306: Missing Authentication for Critical Function vulnerability exists in IGSS (Versions 14 and prior using the service: IGSSupdate), which could allow a local user to execute processes that otherwise require escalation privileges when sending local network commands to the IGSS Update Service.

A CWE-22: Improper Limitation of a Pathname to a Restricted Directory exists in IGSS (Versions 14 and prior using the service: IGSSupdate), which could allow a remote unauthenticated attacker to read arbitrary files from the IGSS server PC on an unrestricted or shared network when the IGSS Update Service is enabled.

A CWE-426: Untrusted Search Path vulnerability exists in ZigBee Installation Kit (Versions prior to 1.0.1), which could cause execution of malicious code when a malicious file is put in the search path.

A CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), reflective DLL, vulnerability exists in EcoStruxure Control Expert (all versions prior to 14.1 Hot Fix), Unity Pro (all versions), Modicon M340 (all versions prior to V3.20), Modicon M580 (all versions prior to V3.10), which, if exploited, could allow attackers to transfer malicious code to the controller.
