TITLE

(0Day) Wecon LeviStudioU usermanage GroupList ID Stack-based Buffer Overflow Remote Code Execution Vulnerability

Trust: 0.7

sources: ZDI: ZDI-18-824

DESCRIPTION

WECON LeviStudio Versions 1.8.29 and 1.8.44 have multiple stack-based buffer overflow vulnerabilities that can be exploited when the application processes specially crafted project files. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Wecon LeviStudioU. 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 handling of UMP files. When parsing the TrendSet WordAddr element, the process does not properly validate 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 Administrator. WECON LeviStudio is a set of human interface programming software from WECON, China
