Dahua IP camera products include an application known as Sonia (/usr/bin/sonia) that provides the web interface and other services for controlling the IP camera remotely. Versions of Sonia included in firmware versions prior to DH_IPC-Consumer-Zi-Themis_Eng_P_V2.408.0000.11.R.20170621 do not validate input data length for the 'password' field of the web interface. A remote, unauthenticated attacker may submit a crafted POST request to the IP camera's Sonia web interface that may lead to out-of-bounds memory operations and loss of availability or remote code execution. The issue was originally identified by the researcher in firmware version DH_IPC-HX1X2X-Themis_EngSpnFrn_N_V2.400.0000.30.R.20160803.","published":"2018-07-24T15:29:01.000Z","lastModified":"2026-06-17T01:17:46.000Z","status":"Modified","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-121","CWE-119"],"affected":["dahuasecurity/ip camera firmware"],"epss":{"score":0.05219,"percentile":0.92468,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (5.22%).
