What is CVE-2022-35507?

A CRLF injection vulnerability exists in the web interface of Proxmox Virtual Environment and Proxmox Mail Gateway. This flaw enables remote attackers to manipulate response headers, potentially allowing them to set excessively long cookies in a victim's browser. The vulnerability primarily affects Chromium-based browsers, as they permit such header injections using the %0d character. As a result, users may experience denial-of-service (DoS) conditions on their clients. This issue has been addressed in version 4.1-3 of the pve-http-server.
