Vulnerability from github
Impact
OctoPrint versions up until and including 1.10.0 contain a vulnerability that allows an unauthenticated attacker to completely bypass the authentication if the autologinLocal
option is enabled within config.yaml
, even if they come from networks that are not configured as localNetworks
, by spoofing their IP via the X-Forwarded-For
header.
If autologin is not enabled, this vulnerability does not have any impact.
Patches
The vulnerability has been patched in version 1.10.1.
Workaround
Until the patch has been applied, OctoPrint administrators who have autologin enabled on their instances should disable it and/or to make the instance inaccessible from potentially hostile networks like the internet.
PoC
- Enable the
autologinAs
configuration within theaccessControl
section in the OctoPrint yaml configuration file - Set your browser to add the
X-Forwarded-For: 127.0.0.1
header to HTTP requests. For example, this can be done using proxy software like Burp Suite. Alternatively, there are browser extensions such as https://github.com/MisterPhilip/x-forwarded-for, but I haven't tried them. - Navigate to OctoPrint and note that it logs you in automatically.
