Trust: 0.8

sources: JVNDB: JVNDB-2020-015352

DESCRIPTION

A vulnerability has been identified in Solid Edge SE2020 (All Versions < SE2020MP12), Solid Edge SE2021 (All Versions < SE2021MP2). Affected applications lack proper validation of user-supplied data when parsing PAR files. This could result in an out of bounds write into uninitialized memory. An attacker could leverage this vulnerability to execute code in the context of the current process. Solid Edge Is vulnerable to an out-of-bounds write.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens Solid Edge Viewer. 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 PAR files. Solid Edge is a combination of software tools to solve various product development processes
