A zip slip vulnerability in XINJE XD/E Series PLC Program Tool up to version v3.5.1 can provide an attacker with arbitrary file write privilege when opening a specially-crafted project file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A zip slip vulnerability in XINJE XD/E Series PLC Program Tool up to version v3.5.1 can provide an attacker with arbitrary file write privilege when opening a specially-crafted project file.
