    Reolink Smart 2K+ Plug-in Wi-Fi Video Doorbell with Chime | Firmware v3.0.0.4662_2503122283

    How the Exploit Works

    The vulnerability arises from how the Reolink Smart 2K+ Plug-in Wi-Fi Video Doorbell manages user sessions. Instead of managing sessions on an account-by-account basis, the system manages them system-wide. An attacker could exploit this flaw by initiating multiple user sessions, leading to resource exhaustion and causing a Denial of Service (DoS).

    Conceptual Example Code

    Below is a conceptual example of how the vulnerability might be exploited. In this case, the attacker initiates multiple user sessions to exhaust system resources:

    POST /initiate_session HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    { "username": "attacker_1", "password": "password" }
    POST /initiate_session HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    { "username": "attacker_2", "password": "password" }
    ...
    ...
    ...
    POST /initiate_session HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    { "username": "attacker_n", "password": "password" }

    This repeated process could exhaust the system resources eventually leading to a denial of service. Users are advised to apply the vendor patch or use WAF/IDS as temporary mitigation.

  • CVE-2025-9255: SQL Injection Vulnerability in WebITR by Uniong

    Overview

    The cybersecurity landscape is ever-evolving, and new vulnerabilities are constantly surfacing. One such vulnerability is the CVE-2025-9255, a SQL Injection vulnerability in WebITR developed by Uniong. This vulnerability allows unauthenticated remote attackers to inject arbitrary SQL commands and read the contents of the database. The vulnerability poses a significant risk for organizations using WebITR, potentially leading to system compromise and data leakage.

    Vulnerability Summary

    CVE ID: CVE-2025-9255
    Severity: High (7.5 CVSS)
    Attack Vector: Network
    Privileges Required: None
    User Interaction: None
    Impact: System compromise and potential data leakage

    Affected Products

    Product | Affected Versions

    WebITR by Uniong | All versions released prior to the patch

    How the Exploit Works

    The vulnerability lies in the improper sanitation of user inputs within WebITR. A remote attacker could exploit this vulnerability by sending specially crafted SQL commands to the application. Since there is no proper sanitation or handling of user inputs, the application executes these commands, giving the attacker the ability to manipulate the database, and potentially read sensitive data.

    Conceptual Example Code

    Here is a
    conceptual
    example of how the vulnerability might be exploited. This is a sample HTTP request:

    POST /login HTTP/1.1
    Host: target.example.com
    Content-Type: application/x-www-form-urlencoded
    username=admin' OR '1'='1'; --&password=

    In this example, the attacker manipulates the ‘username’ field by injecting a SQL command that always evaluates to ‘true’ (‘1’=’1’). The ‘–‘ is a comment in SQL, which makes the application ignore anything after it, including the password check. This could allow the attacker to bypass authentication or reveal sensitive data.

    Mitigation Guidance

    To mitigate this vulnerability, apply the vendor patch as soon as it is available. Until the patch is applied, use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and prevent SQL Injection attacks. Regular audits and proper sanitation of user inputs are also recommended to prevent similar vulnerabilities.
