CyberRota Analysis
AI-GeneratedThe multipart MIME body parser in facil.io versions 0.6.0 to 0.7.6 is vulnerable to an integer underflow that can be exploited by unauthenticated remote attackers. By sending a specially crafted Content-Disposition header with an empty field name, attackers can cause a uint32_t wraparound, leading to an out-of-bounds memory read and crashing the server process. Organizations using these versions of facil.io should prioritize patching this vulnerability to prevent potential denial-of-service attacks.

Original NVD Description
facil.io 0.6.0 through 0.7.6 contains an integer underflow vulnerability in the multipart MIME body parser that allows unauthenticated remote attackers to crash the server process by sending a crafted Content-Disposition header with an empty field name. Attackers can trigger a uint32_t wraparound in http_mime_parser.h causing an out-of-bounds memory read past the name pointer, resulting in a bus fault that crashes the handling worker with a single POST request.
