TITLE

Eaton ELCSoft of elcsoft.exe Heap-based buffer overflow vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2016-003453

DESCRIPTION

Heap-based buffer overflow in elcsoft.exe in Eaton ELCSoft 2.4.01 and earlier allows remote authenticated users to execute arbitrary code via a crafted file. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within processing of EPC files. Parsing a specially crafted EPC file can cause ELCSoft.exe to overwrite a TList object in memory. An attacker can leverage this vulnerability to execute arbitrary code in the context of the process. Eaton ELCSoft Programming Software is a set of software for configuring programmable logic controllers by Eaton, USA. A heap buffer overflow vulnerability exists in Eaton ELCSoft Programming Software 2.4.01 and earlier. Eaton ELCSoft Programming Software is prone to multiple buffer-overflow vulnerabilities because it fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. Failed exploits will result in denial-of-service condition. Eaton ELCSoft 2.4.01 and prior versions are vulnerable
