Full Report
An unpatched security flaw impacting the Edimax IC-7100 network camera is being exploited by threat actors to deliver Mirat botnet malware variants since at least May 2024. The vulnerability in question is CVE-2025-1316 (CVSS v4 score: 9.3), a critical operating system command injection flaw that an attacker could exploit to achieve remote code execution on susceptible devices by means of a
Analysis Summary
# Vulnerability: Unpatched Edimax Camera OS Command Injection Leading to Mirai Botnet Infection
## CVE Details
- CVE ID: CVE-2025-1316
- CVSS Score: 9.3 (Critical - Based on CVSS v4 score mentioned)
- CWE: OS Command Injection (Implied by description)
## Affected Systems
- Products: Edimax IC-7100 network camera (Legacy device)
- Versions: Not explicitly listed, but applies to legacy, discontinued models.
- Configurations: Exploitation relies on the use of default credentials (admin:1234) or successful prior authentication to access the affected endpoint.
## Vulnerability Description
CVE-2025-1316 is a critical operating system command injection vulnerability affecting the Edimax IC-7100 network camera. An attacker can exploit this flaw by sending a specially crafted request to the `/camera-cgi/admin/param.cgi` endpoint. The injection occurs specifically by injecting commands into the `NTP_serverName` option within the `ipcamSource` option of the `param.cgi` request, leading to Remote Code Execution (RCE).
## Exploitation
- Status: Exploited in the wild (Since at least May 2024)
- Complexity: Medium (Requires authentication, potentially via default credentials)
- Attack Vector: Network
## Impact
- Confidentiality: High (Potential for full system compromise leading to data access)
- Integrity: High (Enables remote code execution and persistent compromise)
- Availability: High (Infection leads to device enrollment in a DDoS botnet)
## Remediation
### Patches
- **No official patch available.** Edimax has stated that the affected devices are legacy models, discontinued over 10 years ago, and they have no plans to release a security patch for CVE-2025-1316.
### Workarounds
1. **Upgrade:** Upgrade to a newer, supported camera model.
2. **Isolation:** Avoid exposing the device directly over the internet (e.g., place behind a firewall or restrict remote access).
3. **Credential Change:** Immediately change the default administrative password (`admin:1234`).
4. **Monitoring:** Monitor access logs for signs of unusual activity.
## Detection
- **Indicators of Compromise:** Devices infected with confirmed Mirai variants, or devices showing unexpected outbound network traffic related to DDoS command-and-control infrastructure.
- **Detection Methods and Tools:** Monitor network traffic for requests targeting the `/camera-cgi/admin/param.cgi` endpoint that contain suspicious command injection payloads within the POST body parameters (specifically targeting `ipcamSource` or `NTP_serverName`).
