Description
Some Dahua software products have a vulnerability of unauthenticated un-throttled ICMP requests on remote DSS Server. After bypassing the firewall access control policy, by sending a specific crafted packet to the vulnerable interface, an attacker could exploit the victim server to launch ICMP request attack to the designated target host.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 0.7% probability of exploitation activity in the next 30 days.
