TITLE

Omron CX-One Heap Buffer Overflow Vulnerability

Trust: 0.8

sources: IVD: e2ec2b30-39ab-11e9-8905-000c29342cb1 // CNVD: CNVD-2018-07871

DESCRIPTION

Parsing malformed project files in Omron CX-One versions 4.42 and prior, including the following applications: CX-FLnet versions 1.00 and prior, CX-Protocol versions 1.992 and prior, CX-Programmer versions 9.65 and prior, CX-Server versions 5.0.22 and prior, Network Configurator versions 3.63 and prior, and Switch Box Utility versions 1.68 and prior, may cause a heap-based buffer overflow. Provided by OMRON Corporation CX-One The following applications contain several vulnerabilities: * Stack-based buffer overflow (CWE-121) - CVE-2018-7514 Stack-based buffer overflows can occur due to processing of specially crafted project files. * Accessing resources using inappropriate types ( Mixing of molds ) (CWE-843) - CVE-2018-7530 Due to the processing of a specially crafted project file, access to the outside of the memory area may occur by calling an object with an incorrect type. * Heap-based buffer overflow (CWE-122) - CVE-2018-8834 A heap-based buffer overflow can occur due to the processing of a specially crafted project file.A remote attacker could execute arbitrary code. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OMRON CX-One. 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 the processing of NVF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. The Omron CX-One is an integrated toolkit from Omron, Japan (Omron) that includes networking, PT, frequency converters, temperature controllers, and PLC programming software. CX-FLnet, etc. are all integrated applications. A heap buffer overflow vulnerability exists in multiple softwares in Omron CX-One 4.42 and earlier. Omron CX-Supervisor is prone to the following security vulnerabilities: 1. A stack-based buffer-overflow vulnerability 2. A heap-based buffer-overflow vulnerability 3
