A CWE-501: Trust Boundary Violation vulnerability on connection to the Controller exists in all versions of the Modicon M580, Modicon M340, Modicon Quantum and Modicon Premium which could cause unauthorized access by conducting a brute force attack on Modbus protocol to the controller.

Schneider Electric Telvent Sage 2300 RTUs with firmware before C3413-500-S01, and LANDAC II-2, Sage 1410, Sage 1430, Sage 1450, Sage 2400, and Sage 3030M RTUs with firmware before C3414-500-S02J2, allow remote attackers to obtain sensitive information from device memory by reading a padding field of an Ethernet packet.

Schneider Electric StruxureWare Building Expert MPM before 2.15 does not use encryption for the client-server data stream, which allows remote attackers to discover credentials by sniffing the network.

An Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability exists in IIoT Monitor 3.1.38 which could allow access to files available to SYSTEM user.

A vulnerability exists in Schneider Electric's Pelco Sarix Professional in all firmware versions prior to 3.29.67 which could allow retrieving of specially crafted URLs without authentication that can reveal sensitive information to an attacker.

A Permissions, Privileges, and Access Control vulnerability exists in Schneider Electric's Modicon M221 product (all references, all versions prior to firmware V1.6.2.0). The vulnerability allows unauthorized users to decode the password using rainbow table.

An Information Exposure through Discrepancy vulnerability exists in the embedded web servers in all Modicon M340, Premium, Quantum PLCs and BMXNOR0200 where the web server sends different responses in a way that exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not.

A cleartext transmission of sensitive information vulnerability exists in Schneider Electric's 66074 MGE Network Management Card Transverse installed in MGE UPS and MGE STS. he integrated web server (Port 80/443/TCP) of the affected devices could allow remote attackers to discover an administrative account. If default on device, it is not using a SSL in settings and if multiple request of the page "Access Control" (IP-address device/ups/pas_cont.htm) account data will be sent in cleartext

A Credentials Management CWE-255 vulnerability exists in the APC UPS Network Management Card 2 AOS v6.5.6, which could cause Remote Monitoring Credentials to be viewed in plaintext when Remote Monitoring is enabled, and then disabled.

Vulnerable hash algorithms exists in Schneider Electric's Modicon Premium, Modicon Quantum, Modicon M340, and BMXNOR0200 controllers in all versions of the communication modules. The algorithm used to encrypt the password is vulnerable to hash collision attacks.

In Schneider Electric U.motion Builder software versions prior to v1.3.4, this vulnerability is due to improper validation of input of context parameter in HTTP GET request.

An information disclosure vulnerability exists In Schneider Electric's 66074 MGE Network Management Card Transverse installed in MGE UPS and MGE STS. The integrated web server (Port 80/443/TCP) of the affected devices could allow a remote attacker to obtain sensitive device information if network access was obtained.

Schneider Electric InduSoft Web Studio before 7.1.3.4 SP3 Patch 4 and InTouch Machine Edition 2014 before 7.1.3.4 SP3 Patch 4 provide an HMI user interface that lists all valid usernames, which makes it easier for remote attackers to obtain access via a brute-force password-guessing attack.

A CWE-200: Information Exposure vulnerability exists in Modicon M580, Modicon BMENOC 0311, and Modicon BMENOC 0321, which could cause the disclosure of sensitive information when reading specific registers with the REST API of the controller/communication module.

A CWE-200: Information Exposure vulnerability exists in all versions of the Modicon M580, Modicon M340, Modicon Quantum, and Modicon Premium which could cause the disclosure of SNMP information when reading variables in the controller using Modbus.

An information disclosure vulnerability exists in Schneider Electric's U.motion Builder software versions 1.2.1 and prior in which the system response to error provides more information than should be available to an unauthenticated user.

A CWE-200: Information Exposure vulnerability exists in Modicon M580, Modicon BMENOC 0311, and Modicon BMENOC 0321, which could cause the disclosure of sensitive information when using specific Modbus services provided by the REST API of the controller/communication module.

Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 allows remote attackers to read database records by leveraging access to the guest account.
