How do I patch CVE-2019-0708?

No patch has shipped for CVE-2019-0708 yet — track the huawei agile controller-campus firmware advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2019-0708 across my infrastructure?

Inventory every huawei agile controller-campus firmware deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2019-0708 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2019-0708?

O3 detects and blocks CVE-2019-0708 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2019-0708 actively exploited in the wild?

Yes. There are 152 known exploit references for CVE-2019-0708, including 9 documented proof-of-concept exploits on Exploit-DB and 50 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

Is CVE-2019-0708 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2019-0708 (Microsoft Remote Desktop Services Remote Code Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2021-11-03. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-05-03. The required action was: Apply updates per vendor instructions. This CVE has been used in known ransomware campaigns. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2019-0708?

CVE-2019-0708 is classified as Use After Free (CWE-416). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Which products and versions are affected by CVE-2019-0708?

CVE-2019-0708 affects huawei agile controller-campus firmware (2 versions, e.g. v100r002c00, v100r002c10); huawei bh620 v2 firmware (1 version, e.g. v100r002c00); huawei bh621 v2 firmware (1 version, e.g. v100r002c00); huawei bh622 v2 firmware (1 version, e.g. v100r001c00), and 63 more product(s). Check the affected-products list on this page against your deployed version to confirm exposure.

Is there exploit tooling available for CVE-2019-0708?

4 Metasploit modules reference CVE-2019-0708, which lowers the barrier to weaponization. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.
