Proxmox Virtual Environment is an open-source server management platform for enterprise virtualization. Insufficient safeguards against malicious API response values allow authenticated attackers with 'Sys.Audit' or 'VM.Monitor' privileges to download arbitrary host files via the API. When handling the result from a request handler before returning it to the user, the handle_api2_request function will check for the ‘download’ or ‘data’->’download’ objects inside the request handler call response object. If present, handle_api2_request will read a local file defined by this object and return it to the user. Two endpoints were identified which can control the object returned by a request handler sufficiently that the ’download’ object is defined and user controlled. This results in arbitrary file read. The privileges of this file read can result in full compromise of the system by various impacts such as disclosing sensitive files allowing for privileged session forgery. • https://forum.proxmox.com/threads/proxmox-virtual-environment-security-advisories.149331/post-705345 https://git.proxmox.com/?p=pve-http-server.git;a=blob;f=src/PVE/APIServer/AnyEvent.pm;h=a8d60c18102d2eea9235720852fb60d90f405d0a;hb=HEAD#l988 • CWE-73: External Control of File Name or Path •

Proxmox Virtual Environment (PVE) and Proxmox Mail Gateway (PMG) are vulnerable to SSRF when proxying HTTP requests between pve(pmg)proxy and pve(pmg)daemon. An attacker with an unprivileged account can craft an HTTP request to achieve SSRF and file disclosure of any files on the server. Also, in Proxmox Mail Gateway, privilege escalation to the root@pam account is possible if the backup feature has ever been used, because backup files such as pmg-backup_YYYY_MM_DD_*.tgz have 0644 permissions and contain an authkey value. This is fixed in pve-http-server 4.1-3. Proxmox Virtual Environment (PVE) y Proxmox Mail Gateway (PMG) son vulnerables a SSRF cuando envían solicitudes HTTP entre el proxy pve(pmg) y el daemon pve(pmg). • https://git.proxmox.com/?p=pve-http-server.git%3Ba=commitdiff%3Bh=580d540ea907ba15f64379c5bb69ecf1a49a875f https://git.proxmox.com/?p=pve-http-server.git%3Ba=commitdiff%3Bh=c2bd69c7b5e9c775f96021cf8ae53da3dbd9029d https://git.proxmox.com/?p=pve-http-server.git%3Ba=commitdiff%3Bh=e9df8a6e76b2a18f89295a5d92a62177bbf0f762 https://starlabs.sg/blog/2022/12-multiple-vulnerabilites-in-proxmox-ve--proxmox-mail-gateway • CWE-918: Server-Side Request Forgery (SSRF) •

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. Una vulnerabilidad de inyección CRLF de encabezado de respuesta en la interfaz web Proxmox Virtual Environment (PVE) y Proxmox Mail Gateway (PMG) permite a un atacante remoto configurar cookies para el navegador de una víctima que son más largas de lo que espera el servidor, lo que provoca un DoS del lado del cliente. Esto afecta a los navegadores basados en Chromium porque permiten la inyección de encabezados de respuesta con %0d. • https://git.proxmox.com/?p=pve-http-server.git%3Ba=commitdiff%3Bh=936007ae0241811093155000486da171379c23c2 https://starlabs.sg/blog/2022/12-multiple-vulnerabilites-in-proxmox-ve--proxmox-mail-gateway • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
