| Rule Protection Details |

| Description: | A response-header CRLF injection vulnerability in the Proxmox Virtual Environment (PVE) and Proxmox Mail Gateway (PMG) web interface allows a remote attacker to set cookies for a victim's browser that are longer than the server expects, causing a client-side DoS. This affects Chromium-based browsers because they allow injection of response headers with %0d. This is fixed in pve-http-server 4.1-3. | |
| Impact: | An attacker could exploit this vulnerability to have unspecified effect. | |
| Affected OS: | Windows, Linux, Others | |
