An issue was discovered in Sauter NovaWeb web HMI. The application uses a protection mechanism that relies on the existence or values of a cookie, but it does not properly ensure that the cookie is valid for the associated user.

SAUTER Controls moduWeb firmware version 2.7.1 is vulnerable to reflective cross-site scripting (XSS). The web application does not adequately sanitize request strings of malicious JavaScript. An attacker utilizing XSS could then execute malicious code in users’ browsers and steal sensitive information, including user credentials.

Cross-site scripting (XSS) vulnerability in Sauter EY-WS505F0x0 moduWeb Vision before 1.6.0 allows remote authenticated users to inject arbitrary web script or HTML via a crafted query.

CVE-2023-28655

A malicious user could leverage this vulnerability to escalate privileges or perform unauthorized actions in the context of the targeted privileged users.

CVE-2023-28652

An authenticated malicious user could successfully upload a malicious image could lead to a denial-of-service condition.

CVE-2023-28650

An unauthenticated remote attacker could provide a malicious link and trick an unsuspecting user into clicking on it. If clicked, the attacker could execute the malicious JavaScript (JS) payload in the target’s security context.

CVE-2023-27927

An authenticated malicious user could acquire the simple mail transfer protocol (SMTP) Password in cleartext format, despite it being protected and hidden behind asterisks. The attacker could then perform further attacks using the SMTP credentials.

CVE-2023-22300

An unauthenticated remote attacker could force all authenticated users, such as administrative users, to perform unauthorized actions by viewing the logs. This action would also grant the attacker privilege escalation.

SAUTER Controls Nova 200–220 Series Missing Authentication for Critical Function

SAUTER Controls Nova 200–220 Series with firmware version 3.3-006 and prior and BACnetstac version 4.2.1 and prior allows the execution of commands without credentials. As Telnet and file transfer protocol (FTP) are the only protocols available for device management, an unauthorized user could access the system and modify the device configuration, which could result in the unauthorized user executing unrestricted malicious commands.

SAUTER Controls Nova 200–220 Series Cleartext Transmission of Sensitive Information

SAUTER Controls Nova 200–220 Series with firmware version 3.3-006 and prior and BACnetstac version 4.2.1 and prior have only FTP and Telnet available for device management. Any sensitive information communicated through these protocols, such as credentials, is sent in cleartext. An attacker could obtain sensitive information such as user credentials to gain access to the system.

An XXE vulnerability exists in CASE Suite Versions 3.10 and prior when processing parameter entities, which may allow remote file disclosure.
