VAR-201810-0394
Vulnerability from variot - Updated: 2023-12-18 13:08WECON Technology Co., Ltd. PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior parse files and pass invalidated user data to an unsafe method call, which may allow code to be executed in the context of an administrator. PI Studio HMI and PI Studio Contains an out-of-bounds vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Wecon PIStudio. 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 hsc files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of an administrator. Wecon PIStudio is an HMI software. Wecon PI Studio HMI and PI Studio are human interface programming software from Wecon Technologies. A buffer overflow vulnerability exists in Wecon PI Studio HMI 4.1.9 and earlier and PI Studio 4.2.34 and earlier. WECON PIStudio is prone to a remote code-execution vulnerability. Failed exploit attempts will likely cause denial-of-service conditions
