Full Report
Moxa has reported two critical vulnerabilities in its routers and network security appliances that could allow system compromise and arbitrary code execution
Analysis Summary
Based on the provided context, here is the summarized vulnerability information:
# Vulnerability: Moxa Critical Vulnerabilities (Hard-coded Credentials & Command Injection)
## CVE Details
- CVE ID: CVE-2024-9138, CVE-2024-9140 (Note: Severity scores/CWEs were not provided but implied to be critical)
- CVSS Score: Not specified in the provided text. (Implied High/Critical based on impact description)
- CWE: CWE-798 (Use of Hard-coded Credentials) for CVE-2024-9138; CWE-78 (OS Command Injection) for CVE-2024-9140.
## Affected Systems
- Products: Moxa cellular routers, secure routers, and network security appliances (specific series names were truncated).
- Versions: Specific vulnerable firmware versions were mentioned but truncated in the provided text segment.
- Configurations: Not specified beyond the affected product lines.
## Vulnerability Description
The summary covers two distinct vulnerabilities:
1. **CVE-2024-9138 (Hard-coded Credentials):** Allows an authenticated user to escalate privileges up to root-level access. This allows for system compromise, unauthorized modifications, data exposure, and service disruptions.
2. **CVE-2024-9140 (OS Command Injection):** Involves improperly restricted commands that can be exploited using special characters, potentially leading to arbitrary code execution by an attacker.
## Exploitation
- Status: The article states Moxa identified these and urges immediate updates, suggesting the potential for exploitation exists, but does not explicitly confirm exploitation in the wild. (Inferred status: Unpatched systems are at high risk).
- Complexity: Likely Low/Medium given the nature of hard-coded credentials and command injection which often require minimal prerequisites beyond establishing a session.
- Attack Vector: Not explicitly detailed, but privilege escalation and command injection typically originate via **Network** or **Local** access.
## Impact
- Confidentiality: High (Data exposure/access due to root compromise for CVE-2024-9138).
- Integrity: High (Unauthorized modifications and system compromise for both CVEs).
- Availability: High (Service disruptions possible for CVE-2024-9138).
## Remediation
### Patches
- Moxa has released updates/patches for the affected products. *Specific patch versions were not listed in the provided text.* Users must check the official Moxa advisories for the corresponding fixes for their specific hardware/firmware.
### Workarounds
- No specific workarounds were detailed in the excerpt provided. Immediate patching is strongly urged.
## Detection
- Detection methods were not detailed in the provided excerpt.
- Indicators of compromise would include unauthorized root access attempts, unusual command executions, or system setting changes.
