Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
github.com/warkio/pomf-go
Basic implementation of Pomf.
Note: Only the /upload
path is implemented so far, and it doesn't
handle errors.
go get -u github.com/warkio/pomf-go/cmd/pomf-server
cd "${GOPATH}/bin"
# Copy the `pomf-server` executable to some directory in your $PATH.
#
# This assumes you want to put it in `${HOME}/bin`.
cp pomf-server "${HOME}/bin"
export POMF_LISTEN_ADDRESS='127.0.0.1:8000'
# The resulting file URL will just concatenate this with the file name,
# so you might want to make sure there's a trailing slash.
export POMF_URL_PREFIX='https://example.com/'
# Where to put the files.
export POMF_UPLOAD_DIRECTORY='./files/'
pomf-server
curl -i -sSF 'files[]=@waifu.png' 'https://127.0.0.1:8000/upload'
