QNAP 0-day Flaw

Palo Alto mentioned that, this vulnerability is connected to a uncover injection which exists in the short.cgi component of QNAP QTS firmware that is liable to be accessed with out authentication. QNAP QTS stands for (QNAP Turbo community linked storage Machine).

When environment the HTTP parameter todo=set_timeinfo, the short.cgi seek information from of handler saves the value of the parameter SPECIFIC_SERVER into the configuration file /tmp/immediate/quick_tmp.conf under the name NTP Tackle.

After this, the short.cgi component starts time synchronization with the ntpdate utility where the uncover-line execution occurs.

This utility reads the NTP Tackle in the quick_tmp.conf file which is then carried out the exhaust of procedure().

This implies that if an untrusted enter is supplied in the SPECIFIC_SERVER parameter, it’s a long way handed thru the phases and carried out through procedure() ensuing in an arbitrary uncover execution on the inclined instrument.

Mitigation

So as to mitigate this vulnerability, customers can apply the under mentioned steps

• Test the URL: https://:/cgi-bin/immediate/immediate.cgi on the browser
• If there could be a HTTP 404 Error, the instrument is no longer inclined. If there could be a “Net page No longer Chanced on” or “the uncover server is currently accessible”, there could be a possibility of vulnerability on the instrument.
• If there would possibly be an empty web page with HTTP 200 response, the following steps are on the spot:
  • Update your working procedure to one amongst the following variations or later:
    • QTS 5.0.0.1986 make 20220324 or later
    • QTS 4.5.4.2012 make 20220419 or later
    • QuTS h5.0.0.1986 make 20220324 or later
    • QuTS h4.5.4.1991 make 20220330 or later
• Retest the identical URL on the uncover browser. If the tip consequence’s an HTTP 404 error, the instrument is secured.
• If the HTTP 200 response silent persists, contacting QNAP technical increase is on the spot.
