Trust: 0.8

sources: JVNDB: JVNDB-2018-015137

DESCRIPTION

WECON Technology PI Studio HMI versions 4.1.9 and prior and PI Studio versions 4.2.34 and prior lacks proper validation of user-supplied data, which may result in a read past the end of an allocated object. WECON Technology PI Studio HMI and PI Studio Contains an out-of-bounds vulnerability.Information may be obtained. This vulnerability allows remote attackers to disclose sensitive information 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 images within DAT files. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of an administrator. The vulnerability stems from the program's failure to properly validate user-submitted data. No detailed vulnerability details are provided at this time. Failed exploit attempts will likely cause denial-of-service conditions
