Horizon Alert
Summary of the vulnerability and why it matters
Multiple command injection vulnerabilities exist in several H3C network devices, allowing remote attackers to execute arbitrary commands as root. This means an attacker could potentially gain complete control over the affected devices, impacting their functionality and security. The main concern is confirming the relevance and exposure of these devices within your environment.
- Attackers can run any command on devices.
- This threat allows full device compromise.
- Confirm if these specific devices are used.
Attack Path
How an attacker could exploit the issue
An attacker can exploit command injection vulnerabilities in the `/api/esps` request handler by sending specially crafted parameters. These parameters are then executed as shell commands without proper sanitization, allowing the attacker to run arbitrary commands as root. This can lead to full control over the affected network device.
- Network exposure required.
- Unvalidated request parameters trigger vulnerability.
- Complete device control is the risk.
Live Threat
Current exploitation, exposure, and threat context
The identified command injection vulnerabilities in several H3C network devices could allow a remote attacker to execute arbitrary commands as the root user, leading to complete device compromise. This could occur when an attacker crafts malicious requests to specific API interfaces, such as those handling DHCP, URL filtering, or system settings. The underlying issue stems from improperly validated user input being incorporated into system shell commands.
- Affected asset: Network device.
- Exposure: Exploiting unvalidated request parameters.
- Consequence: Complete device control.
Operational Fix
Recommended remediation, mitigation, and detection steps
This critical vulnerability in H3C network devices allows unauthenticated remote attackers to execute arbitrary commands as root. Responsibility for addressing this typically falls to network infrastructure teams, potentially in coordination with vendor management if devices are externally sourced. The first practical step is to identify all deployed instances of the affected H3C models, determine their network exposure and business criticality, and then plan remediation.
- Network infrastructure teams should own the issue.
- Verify network exposure and device criticality.
- Plan coordinated vendor-assisted remediation.
