CVE-2018-12940
Unrestricted file upload vulnerability in "op/op.UploadChunks.php" in SeedDMS (formerly LetoDMS and MyDMS) before 5.1.8 allows remote attackers to execute arbitrary code by uploading a file with an executable extension specified by the "qqfile" parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
