Description

Statmatic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.11 and 6.4.0, when Glide image manipulation is used in insecure mode (which is not the default), the image proxy can be abused by an unauthenticated user to make the server send HTTP requests to arbitrary URLs—either via the URL directly or via the watermark feature. That can allow access to internal services, cloud metadata endpoints, and other hosts reachable from the server. This has been fixed in 5.73.11 and 6.4.0.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, an attacker needs no privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Changed — a successful attack reaches components beyond the vulnerable one.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: None.
  • Availability impact: None.
