Detailsinfo

A vulnerability was found in Rockwell FactoryTalk Linx Software, RSLinx Classic, RSNetWorx Software and Logix Designer Software (the affected version unknown). It has been classified as problematic. This affects an unknown part of the component EDS Subsystem. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on availability. The summary by CVE is:

Products that use EDS Subsystem: Version 28.0.1 and prior (FactoryTalk Linx software (Previously called RSLinx Enterprise): Versions 6.00, 6.10, and 6.11, RSLinx Classic: Version 4.11.00 and prior, RSNetWorx software: Version 28.00.00 and prior, Studio 5000 Logix Designer software: Version 32 and prior) is vulnerable. A memory corruption vulnerability exists in the algorithm that matches square brackets in the EDS subsystem. This may allow an attacker to craft specialized EDS files to crash the EDSParser COM object, leading to denial-of-service conditions.

The weakness was published 05/19/2020. This vulnerability is uniquely identified as CVE-2020-12038 since 04/21/2020. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.
