Older versions of the S7-1500 CPU are affected by two Denial-of-Service vulnerabilities. Siemens has released updates for the currently supported hardware versions.

The latest update for SIMATIC Panel software and SIMATIC WinCC (TIA Portal) fixes two web vulnerabilities. The most severe is a vulnerability which could allow an attacker with network access to the integrated webserver to download arbitrary files. Siemens recommends to update to the newest version.

Two vulnerabilities have been identified in SIEMENS LOGO!8 BM devices. The most severe vulnerability could allow an attacker to hijack existing web sessions. Siemens provides LOGO!8 BM FS-05 with firmware version V1.81.2, which fixes the first vulnerability, and recommends specific mitigations for the second vulnerability.

A vulnerability in the affected devices could allow an unauthenticated attacker with network access to an affected device to perform a denial-of-service. Siemens is preparing updates and recommends specific countermeasures until patches are available.

The latest update for TIM 1531 IRC fixes a security vulnerability that could allow unauthorized remote attackers to perform administrative operations on the device. Siemens recommends updating as soon as possible.

Two vulnerabilities have been identified in the SIMATIC S7-400 CPU family that could allow an attacker to cause a Denial-of-Service condition. In order to exploit the vulnerability, an attacker must have access to the affected devices on port 102/tcp via Ethernet, PROFIBUS or Multi Point Interfaces (MPI). Siemens provides updates …

A denial of service vulnerability was found in several Siemens Scalance X switches. Siemens addresses the vulnerability by two firmware upgrades. The web server of the vulnerable switches is susceptible to a remote denial of service attack. If the attack is executed, it causes a reboot of the device and …
