Nozomi Networks Discovers Vulnerability in Siemens Building Automation Software

Recently, we had the opportunity to do a security analysis of the Siemens PXC4.E16, a Building Automation System (BAS) of the Desigo/APOGEE family for HVAC and building service plants. In this blog, we are publishing the details of a vulnerability that was caused by an improper implementation of the password-based key derivation mechanism for user accounts. It could also have been abused to perform a Denial-of-Service (DoS) attack against the controller.

We’ve introduced Selective Data Synchronization to our Vantage SaaS platform so customers benefit from easier licensing and configuration while allowing for data residency concerns.

Nozomi Networks Discovers Unpatched DNS Bug in Popular C Standard Library Putting IoT at Risk

Nozomi Networks Labs discovered a vulnerability (tracked under CVE-2022-05-02, ICS-VU-638779, VU#473698) affecting the Domain Name System (DNS) implementation of all versions of uClibc and uClibc-ng, a popular C standard library in IoT products. The flaw is caused by the predictability of transaction IDs included in the DNS requests generated by the library, which may allow attackers to perform DNS poisoning attacks against the target device.
