Vulnerability from variot
A use after free issue has been identified in the way ISPSoft(v3.12 and prior) processes project files, allowing an attacker to craft a special project file that may allow arbitrary code execution. Delta Electronics The following vulnerabilities exist in multiple products provided by the company. ‥ * Use of freed memory (Use-after-free) (CWE-416) - CVE-2020-27280 ‥ * Untrusted pointer reference (CWE-822) - CVE-2020-27288 ‥ * Out-of-bounds writing (CWE-787) - CVE-2020-27284Both vulnerabilities could allow arbitrary code to be executed with application privileges by processing a specially crafted project file. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Industrial Automation ISPSoft. 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 ISP files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Delta Electronics ISPSoft is a set of PLC (Programmable Logic Controller) programming software of Delta Electronics, Taiwan, China.
Delta Electronics ISPSoft v3.12 and prior has an access control error vulnerability, which is caused by the network system or product improperly restricting access to resources from unauthorized roles
