Security News > 2023 > July > CISA: Citrix RCE bug exploited to breach critical infrastructure org
Threat actors have breached the network of a U.S. organization in the critical infrastructure sector after exploiting a zero-day RCE vulnerability currently identified as CVE-2023-3519, a critical-severity issue in NetScaler ADC and Gateway that Citrix patched this week.
Because the targeted NetScaler ADC appliance was in a segregated environment on the network, the hackers were not able to move laterally to a domain controller, CISA says.
CISA has released an advisory with tactics, techniques, and procedures along with detection methods to help organizations, particularly those in the critical infrastructure segment, determine if their systems were compromised.
With threat actors exploiting the vulnerability since it was a zero-day, NetScaler admins should install without delay the latest updates Citrix released to address the issue.
