|CVSS SCORE||7.8, (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)|
This vulnerability allows remote attackers to execute arbitrary code on affected 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 parsing of XY tags within UMP files. When parsing the WordAddr10 attribute, 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 in the context of the current process.
This vulnerability is being disclosed publicly without a patch in accordance with the ZDI 120 day deadline.
