TITLE

Carlo Gavazzi VMU-C EM and VMU-C PV Vulnerability that important information in firmware is saved in clear text

Trust: 0.8

sources: JVNDB: JVNDB-2017-001715

DESCRIPTION

An issue was discovered in Carlo Gavazzi VMU-C EM prior to firmware Version A11_U05, and VMU-C PV prior to firmware Version A17. Sensitive information is stored in clear-text. Carlo Gavazzi VMU-C EM and VMU-C PV Firmware contains a vulnerability that allows important information to be stored in clear text.Important information may be stored in clear text. CarloGavazziAutomationVMU-CEM and VMU-CPV are control modules in the automation products of Italy's CarloGavazzi Automation. Multiple Carlo Gavazzi products are prone to an unauthorized-access vulnerability, a cross-site request-forgery vulnerability and an information-disclosure vulnerability. Exploiting these issues may allow a remote attacker to gain access to the sensitive information, or perform certain administrative actions and gain unauthorized access to the affected application. Other attacks are also possible. *VMU-C Web-Server solution for photovoltaic applications* VMU-C EM is a data logger system for small to medium projects, VMUC-Y EM is a hardware data aggregator for medium to larger projects and Em2 Server is a software solution for large projects. They are designed to complement the extensive line of Carlo Gavazzi energy meters and current transformers. Weak Credentials Management* -> admin/admin -> Application does not enforce mandatory password change *2. Access Control flaws* 1. Access control is not enforced correctly 2. Certain application functions can be accessed without any authentication 3. Application stores the Energy / Plant data in a sqlite database - EWPlant.db. Anyone can dump plant database file - without any authentication *4. Reflected + Stored XSS - multiple URLs, parameters - *Not documented in ICS-CERT Advisory Successful exploitation of this vulnerability could allow an unauthenticated attacker to inject arbitrary JavaScript in a specially crafted URL request where the response containing user data is returned to the web browser without being made safe to display. *5. Vulnerable to Cross-Site Request Forgery* There is no CSRF Token generated per page and / or per (sensitive) function. Successful exploitation of this vulnerability can allow silent execution of unauthorized actions on the device such as configuration parameter changes, and saving modified configuration. +++++
