A vulnerability exists in affected products that could allow remote attackers to affect the availability of the devices under certain conditions. The underlying TCP stack can be forced to make very computation expensive calls for every incoming packet which can lead to a Denial-of-Service.

Security researchers discovered and disclosed seven vulnerabilities in the open-source DNS component “dnsmasq”, also known as “DNSpooq” vulnerabilities (CVE-2020-25681 through CVE-2020-25687). Three vulnerabilities (CVE-2020-25684 through CVE-2020-25686) affect the validation of DNS responses and impact several SCALANCE and RUGGEDCOM devices as listed below. Siemens is preparing updates and recommends countermeasures for …

The Climatix BACnet/IP (POL908) and AWM (POL909) modules contain two persistent cross-site scripting (XSS) vulnerabilities in the web interface that could allow a remote attacker to execute arbitrary JavaScript code in the context of other users’ web sessions. Siemens has released an update for Climatix POL909 and recommends to update …

Several industrial products are affected by a vulnerability that could allow remote attackers to conduct a Denial-of-Service (DoS) attack by sending specially crafted packets to port 161/udp (SNMP). Siemens has released updates for several affected products and recommends to update to the new versions. Siemens is preparing further updates and …

Several SCALANCE X switches contain a vulnerability that could allow an attacker to perform administrative actions if the victim is tricked into clicking on a website controlled by the attacker. The attack only works if the victim has an authenticated session on the administrative interface of the switch. Siemens has …

There exists a directory traversal vulnerability which allows arbitrary file upload to an affected system. This type of vulnerability is also known as ‘Zip-Slip’. An authenticated attacker could exploit this vulnerability to gain arbitrary code execution by uploading a new or modifying an existing file to an affected system. Siemens …

Some versions of Mentor Nucleus ReadyStart and Nucleus NET use Initial Sequence Numbers for TCP- Sessions that are predictable. Siemens has released updates for the affected products and recommends to update to the latest version(s).
