描述

A PoC exploit for CVE-2010-4231 - Directory Traversal Vulnerability in Camtron and TecVoz IP Cameras.

介绍

# CVE-2010-4231 - Directory Traversal Vulnerability in Camtron and TecVoz IP Cameras

CVE-2010-4231 is a directory traversal vulnerability that exists in the web-based administration interface of the Camtron CMNC-200 Full HD IP Camera and TecVoz CMNC-200 Megapixel IP Camera. The vulnerability allows remote attackers to read arbitrary files by exploiting a ".." (dot dot) traversal sequence in the URI.
# Vulnerable Devices

    Camtron CMNC-200 Full HD IP Camera with firmware 1.102A-008
    TecVoz CMNC-200 Megapixel IP Camera with firmware 1.102A-008

# Impact and Severity

This vulnerability poses a significant security risk as it allows unauthorized access to sensitive files on the affected devices. Exploitation of this flaw could lead to the exposure of critical information or system files, potentially facilitating further attacks on the camera or the network to which it is connected.

Severity: High

# Mitigation

To mitigate the risk associated with CVE-2010-4231, users of the affected Camtron and TecVoz IP cameras are strongly advised to take the following actions:

    Update Firmware: The first step is to ensure that the cameras are running the latest firmware version available from the manufacturer. Check the official website of Camtron or TecVoz for firmware updates and follow their guidelines for updating the firmware on the devices.
    Restrict Access: Limit access to the web-based administration interface to trusted IP addresses only. Implement firewall rules or access control lists (ACLs) to prevent unauthorized access to the camera's management interface.
    Network Segmentation: Consider placing the IP cameras on a separate and isolated network segment, away from critical assets and sensitive data. This practice can prevent attackers from gaining unauthorized access to other parts of the network in case of a successful breach.
    Regular Security Audits: Conduct periodic security audits of the IP camera's configuration and ensure that any unnecessary services or ports are disabled. Also, verify that default credentials have been changed to strong, unique passwords.
    Vendor Communication: Report the vulnerability to Camtron or TecVoz, depending on the affected camera model, to ensure that they are aware of the issue and can take appropriate measures to address it.

# How the Vulnerability Works

The vulnerability arises due to insufficient input validation in the affected cameras' web-based administration interface. When handling requests containing directory traversal sequences ("../"), the cameras fail to properly validate and sanitize user-supplied input. As a result, an attacker can craft malicious HTTP requests with "../" sequences to navigate to directories outside of the intended path.

By exploiting this flaw, an attacker can read arbitrary files on the filesystem, potentially disclosing sensitive information, configuration files, or other data that could aid in further attacks on the device or the network it is connected to.

# Proof of Concept (PoC)

To demonstrate the vulnerability, consider the following example:

GET /../../../../../etc/passwd HTTP/1.1
Host: target-camera.com

In this PoC, the attacker sends a crafted HTTP request containing multiple "../" sequences, aiming to access the "/etc/passwd" file on the target camera's filesystem. If successful, the contents of the passwd file would be returned in the HTTP response, potentially revealing sensitive user account information.

Note: The provided PoC is for illustrative purposes only and should not be used against any system without explicit authorization.

# Disclaimer

This advisory describes a known security vulnerability in the specified Camtron and TecVoz IP camera models. It is essential to follow responsible disclosure practices and adhere to the terms and conditions set forth by the camera manufacturers.
