    Field note · Priya NairCurated

    Directory traversal → unauth RCE on Citrix ADC/Gateway. 'Shitrix.' Mass-exploited over the 2019/2020 holidays while the patch lagged the mitigation. Classic edge-appliance disaster.

    Patch the firmware; the early mitigation (responder policy) was bypassable, so don't rely on it. Hunt for webshells under /netscaler/portal/templates.
