CVE-2008-4930

MyBB 1.4.2 - HTML Injection via Nonstandard File Type Upload

Title source: llm
STIX 2.1

Description

MyBB (aka MyBulletinBoard) 1.4.2 does not properly handle an uploaded file with a nonstandard file type that contains HTML sequences, which allows remote attackers to cause that file to be processed as HTML by Internet Explorer's content inspection, aka "Incomplete protection against MIME-sniffing." NOTE: this could be leveraged for XSS and other attacks.
