CVE-2014-3088

Status: ModifiedMedium (5.5)—

stconf.nsf in IBM Sametime Meeting Server 8.5.1 relies on the client to validate the file format used in wAttach?OpenForm multipart/form-data POST requests, which allows remote authenticated users to bypass intended upload restrictions by modifying the Content-Type header and file extension, as demonstrated by replacing a text/plain .txt upload with an application/octet-stream .exe upload.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:S/C:P/I:P/A:N
