CVE-2026-29116: CWE-617 in Dahua IPC/SD/NVR/XVR/EVS/VTO/VTH/ASI/TPC
A denial of service vulnerability (CWE-617) exists in certain Dahua IPC, SD, NVR, XVR, EVS, VTO, VTH, ASI, and TPC devices. An unauthenticated remote attacker can send a specially crafted packet that triggers an exception causing the device to reboot unexpectedly. This disrupts normal operation and availability of the affected devices. The vulnerability affects versions built before March 26, 2026. No official patch or remediation guidance has been provided yet.
AI Analysis
Technical Summary
CVE-2026-29116 is a denial of service vulnerability in multiple Dahua device models (IPC, SD, NVR, XVR, EVS, VTO, VTH, ASI, TPC). It allows an unauthenticated remote attacker to send a crafted packet that triggers an exception, causing the system to reboot unexpectedly. This results in service disruption. The vulnerability is identified as CWE-617 (Reachable Assertion). The CVSS 4.0 base score is 8.7 (high severity), reflecting network attack vector, no privileges or user interaction required, and high impact on availability. Affected versions are those built before March 26, 2026. There is no vendor advisory or patch information available at this time.
Potential Impact
Successful exploitation causes unexpected system reboots leading to denial of service on affected Dahua devices. This disrupts device availability and may impact security monitoring or operations relying on these devices. No data confidentiality or integrity impacts are indicated.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting network exposure of affected devices and monitoring for unusual reboot behavior.
