Description

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.

• CWE-805Buffer Access with Incorrect Length ValueThe 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.
• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
