Arbitrary File Upload Vulnerability in DedeCMS V5.7SP2

CVE-2019-8362 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:P/A:N

DedeCMS through V5.7SP2 allows arbitrary file upload in dede/album_edit.php or dede/album_add.php, as demonstrated by a dede/album_edit.php?dopost=save&formzip=1 request with a ZIP archive that contains a file such as "1.jpg.php" (because input validation only checks that .jpg, .png, or .gif is present as a substring, and does not otherwise check the file name or content).
