Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	None	—	No published hardware-tampering research specific to this model was found as of 2026-10. The housing is sealed and the reset button and microSD slot are internal.
Known vulnerabilities	Rare	🔗 Proof	CVE-2022-30563 (CVSS 7.4): ONVIF login packets can be captured and replayed by a man-in-the-middle to authenticate to the device. NVD lists ipc-hdbw2431e-s-s2 explicitly among the 40 affected models. No other model-specific CVE was found for this camera.
Prior attacks	Rare	—	No campaign specifically naming this model was found. Dahua cameras generally are a recurring IoT botnet target, but no direct evidence links this particular model to a recorded attack, so the value is kept low and is provisional.
Updatability	Rare	🔗 Proof	Dahua runs a PSIRT and publishes firmware and advisories, but updates are applied manually via the web interface or a local tool; there is no automatic update channel, so deployed units frequently stay unpatched.
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Partial	🔗 Proof	Authentication towards other systems over ONVIF is only partially effective: a captured successful login can be replayed verbatim, so the authentication check does not bind the session to the original requester.
Communications	No encryption	🔗 Proof	CVE-2022-30563 exists precisely because ONVIF login traffic can be sniffed on the network, which shows that this traffic is not protected against interception. RTSP and HTTP streams are likewise unencrypted by default.
Storage	No encryption	—	Recordings written to the local microSD card are not encrypted at rest. Provisional value, not directly evidenced for this model.
Category Score	Score: 3 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Basic	—	The web interface offers a fixed role set (admin/operator/user) without granular permissions. Provisional value, not directly evidenced for this model.
Authentication	Basic	🔗 Proof	Username/password login exists on the web interface and ONVIF, but CVE-2022-30563 allows an attacker who has captured one successful ONVIF login to replay it and authenticate without knowing the password.
Brute-force protection	Absent	—	No documented account lockout or rate limiting on failed logins; mass password-guessing against Dahua cameras is a known practice. Provisional value, not directly evidenced for this model.
Event logging	Partial logging	—	The camera keeps a local log viewable in the web interface, with no centralised or tamper-evident logging. Provisional value, not directly evidenced for this model.
Passwords	Require change after setup	—	Dahua firmware requires an admin password to be set on first initialisation and does not ship a fixed factory default, but no complexity rule is enforced.
Category Score	Score: 3 / 3

The Dahua IPC-HDBW2431E-S-S2 is a 4MP fixed dome network camera from Dahua's entry-level Lite series. Its only model-level publicly documented weakness is CVE-2022-30563 (CVSS 7.4), an ONVIF login replay flaw: an attacker who can observe one successful ONVIF authentication can replay those packets and log in without the password. NVD lists ipc-hdbw2431e-s-s2 explicitly among the affected models, so the exposure is confirmed at model level rather than inferred from a product family. The impact is bounded by the requirement for a man-in-the-middle position, which is why the vulnerability criteria are scored Rare rather than Very common. Dahua operates a PSIRT and ships patched firmware, but updates are manual, so unpatched units persist in the field. The device is rated D: a real authentication bypass is documented for this exact model, and the remaining user-authentication controls do not compensate for it, but exploitation requires network positioning and no mass-exploitation campaign against this model was found. Values for hardware tampering, prior attacks, storage encryption, account management, brute-force protection, event logging and password policy are provisional because no model-level Dahua documentation could be retrieved; the rating rests on the CVE-2022-30563 evidence.
