Two new unpatched zero-day vulnerabilities in Citrix NetScaler ADC and NetScaler Gateway appliances that allow remote code execution are being actively exploited in the wild, security firm watchTowr said on September 26.
Summary
Citrix has not confirmed the flaws or published a fix. Some administrators say they have taken appliances offline rather than wait for one to be available.
This is a brief wire summary — the full story (linked below) has the complete details.
KazaSec's take
Incidents like this rarely start with the headline event itself — they usually trace back to an exposed remote-access endpoint, an unpatched perimeter system, or a credential phished weeks earlier. The organizations that recover fastest are the ones that tested their defenses and their incident response plan before they needed them.
