Siemens SIMATIC PC-Station Plus up to 5.1 buffer access with incorrect length value

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Siemens SIMATIC PC-Station Plus, SIMATIC S7-400 CPU 412-2 PN V7, SIMATIC S7-400 CPU 414-3 PN, DP V7, SIMATIC S7-400 CPU 414F-3 PN, SIMATIC S7-400 CPU 416-3 PN, SIMATIC S7-400 CPU 416F-3 PN, SINAMICS S120 (incl. SIPLUS variants), SIPLUS S7-400 CPU 414-3 PN and SIPLUS S7-400 CPU 416-3 PN up to 5.1 (SCADA Software). It has been rated as critical. This issue affects an unknown functionality. The manipulation with an unknown input leads to a buffer access with incorrect length value vulnerability. Using CWE to declare the problem leads to CWE-805. The product uses a sequential operation to read or write a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer. Impacted is availability. The summary by CVE is:

A vulnerability has been identified in SIMATIC PC-Station Plus (All versions), SIMATIC S7-400 CPU 412-2 PN V7 (All versions), SIMATIC S7-400 CPU 414-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 414F-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 416-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 416F-3 PN/DP V7 (All versions), SINAMICS S120 (incl. SIPLUS variants) (All versions < V5.2 SP3 HF15), SIPLUS S7-400 CPU 414-3 PN/DP V7 (All versions), SIPLUS S7-400 CPU 416-3 PN/DP V7 (All versions). The affected products do not handle long file names correctly. This could allow an attacker to create a buffer overflow and create a denial of service condition for the device.
