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.

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.

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.

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.

An Improper Restriction of XML External Entity Reference ('XXE') vulnerability exists on numerous methods of the IIoT Monitor 3.1.38 software that could allow the software to resolve documents outside of the intended sphere of control, causing the software to embed incorrect documents into its output and expose restricted information.

Schneider Electric SoMachine Basic prior to v1.6 SP1 suffers from an XML External Entity (XXE) vulnerability using the DTD parameter entities technique resulting in disclosure and retrieval of arbitrary data on the affected node via out-of-band (OOB) attack. The vulnerability is triggered when input passed to the xml parser is not sanitized while parsing the xml project/template file.

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.

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.

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

In Schneider Electric Wiser for KNX V2.1.0 and prior, homeLYnk V2.0.1 and prior; and spaceLYnk V2.1.0 and prior, weak and unprotected FTP access could allow an attacker unauthorized access.

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 files from the controller over Modbus

An exposure of sensitive information vulnerability exists in Schneider Electric's Pelco VideoXpert Enterprise versions 2.0 and prior. Using a directory traversal attack, an unauthorized person can view web server files.

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.

Schneider Electric Modicon TM221CE16R 1.3.3.3 devices allow remote attackers to discover the application-protection password via a \x00\x01\x00\x00\x00\x05\x01\x5a\x00\x03\x00 request to the Modbus port (502/tcp). Subsequently the application may be arbitrarily downloaded, modified, and uploaded.

A Violation of Secure Design Principles issue was discovered in Schneider Electric Modicon Modbus Protocol. The Modicon Modbus protocol has a session-related weakness making it susceptible to brute-force attacks.

An Insufficiently Protected Credentials issue was discovered in Schneider Electric Modicon PLCs Modicon M241, all firmware versions, and Modicon M251, all firmware versions. Log-in credentials are sent over the network with Base64 encoding leaving them susceptible to sniffing. Sniffed credentials could then be used to log into the web application.

A CWE-425: Direct Request ('Forced Browsing') vulnerability exists in the Web Server on Modicon M340, Legacy Offers Modicon Quantum and Modicon Premium and associated Communication Modules (see security notification for affected versions), that could cause disclosure of sensitive data when sending a specially crafted request to the controller over HTTP.

A CWE-200: Information Exposure vulnerability exists in Easergy T300 (Firmware version 1.5.2 and older) which could allow attacker to obtain private keys.

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.
