Lifecycle Timeline
8DescriptionCVE.org
A security vulnerability has been detected in H3C Magic B0 up to 100R002. This vulnerability affects the function Edit_BasicSSID of the file /goform/aspForm. Such manipulation of the argument param leads to buffer overflow. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Buffer overflow in H3C Magic B0 routers (firmware versions up to 100R002) allows authenticated remote attackers to achieve arbitrary code execution via the Edit_BasicSSID function in /goform/aspForm. Public exploit code exists on GitHub. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Valid low-privilege administrative credentials to the H3C Magic B0 router web management interface. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is MODERATE-HIGH for deployed devices but constrained by authentication requirement. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker obtains valid administrative credentials for an H3C Magic B0 router through password reuse from a previous breach or social engineering. They craft a malicious HTTP POST request to the /goform/aspForm endpoint, targeting the Edit_BasicSSID function with an oversized 'param' value designed to overflow the input buffer. … |
| Remediation | No vendor-released patch identified at time of analysis - H3C did not respond to vulnerability disclosure per CVE description. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Inventory all H3C Magic B0 routers in production and document firmware versions; restrict administrative access to these devices to hardened jump hosts only. …
