Device crash via malformed HTTP header parsing
Published Oct 25, 2024 · Updated Oct 25, 2024
Out-of-bounds reads in Sharp and Toshiba Tec MFP firmware allow remote attackers to crash devices with crafted HTTP headers. The device web server's HTTP header parser reads beyond a buffer boundary when it handles a malformed header; no deeper code-level detail is public. Network access to the MFP web interface is required, and the documented effect is a device hang without data leakage.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
