TITLE

Delta Industrial Automation DOPSoft Buffer Overflow Vulnerability

Trust: 0.8

sources: IVD: e2ff8c21-39ab-11e9-a399-000c29342cb1 // CNVD: CNVD-2018-12139

DESCRIPTION

Delta Electronics Delta Industrial Automation DOPSoft version 4.00.04 and prior utilizes a fixed-length stack buffer where a value larger than the buffer can be read from a .dpa file into the buffer, causing the buffer to be overwritten. This may allow remote code execution or cause the application to crash. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Delta Industrial Automation DOPSoft. 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 parsing of fields in DPA files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. Delta Electronics Delta Industrial Automation DOPSoft is a set of human interface applications from Delta Electronics. A remote code-execution vulnerability 2. A stack-based buffer-overflow vulnerability 3. Failed attacks will cause denial of service conditions. DOPSoft 4.00.04 and prior are vulnerable
