## What is CVE-2017-9316?

CVE-2017-9316 is a medium-severity authentication bypass vulnerability in Dahua Technologies IPC-HDW4300S\NVR11HS\IPC-HFW4X00\IPC-HDW4X00\IPC-HDBW4X00\IPC-HF5X00\IPC-HFW5X00\IPC-HDW5X00\IPC-HDBW5X00\NVR11HS, published on 27 Nov 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Firmware upgrade authentication bypass vulnerability was found in Dahua IPC-HDW4300S and some IP products. The vulnerability was caused by internal Debug function. This particular function was used for problem analysis and performance tuning during product development phase. It allowed the device to receive only specific data (one direction, no transmit) and therefore it was not involved in any instance of collecting user privacy data or allowing remote code execution.

Weakness: CWE-287 (Improper Authentication)

What it is: CVE-2017-9316 is a medium-severity authentication bypass vulnerability in Dahua Technologies IPC-HDW4300S\NVR11HS\IPC-HFW4X00\IPC-HDW4X00\IPC-HDBW4X00\IPC-HF5X00\IPC-HFW5X00\IPC-HDW5X00\IPC-HDBW5X00\NVR11HS, published on 27 Nov 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-9316 in the wild and no public exploit code.

Affected product: Dahua Technologies IPC-HDW4300S\NVR11HS\IPC-HFW4X00\IPC-HDW4X00\IPC-HDBW4X00\IPC-HF5X00\IPC-HFW5X00\IPC-HDW5X00\IPC-HDBW5X00\NVR11HS. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
