A vulnerability was found in Cianet ONU GW24AC up to 20250127. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the component Login. The manipulation of the argument browserLang leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
With a CVSS score of 5.3, this vulnerability is classified as medium severity. Organizations should assess the impact of this vulnerability as it allows attackers to perform cross-site scripting attacks, potentially leading to unauthorized actions on behalf of users.
Organizations should prioritize patching immediately. Although the vulnerability is currently deferred, the public disclosure of the exploit details increases the urgency for defenders.
As this vulnerability is associated with cross-site scripting, it is crucial for organizations to ensure that user input is sanitized adequately to prevent exploitation.
Vulnerability Details
The vulnerability affects the Cianet ONU GW24AC up to version 20250127. It has been classified under several Common Weakness Enumeration (CWE) identifiers, specifically CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Improper Control of Generation of Code ('Code Injection')).
The vulnerability allows attackers to manipulate the argument browserLang, leading to potential cross-site scripting attacks. The attack vector is classified as NETWORK, and the attack complexity is LOW, indicating that the vulnerability can be exploited with minimal effort.
Given the nature of the vulnerability and its public disclosure, organizations should remain vigilant and address this vulnerability as part of their risk management strategy.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user input during the login process. Specifically, the browserLang argument is not adequately sanitized, allowing malicious scripts to be injected into the web application.
The attack can be executed remotely without requiring authentication, making it particularly concerning for organizations. Attack complexity is low, as a passive user interaction can trigger the exploit once the payload is delivered.
Exploitation could lead to low integrity impact, where attackers can manipulate user sessions and potentially hijack user accounts. The availability impact remains unaffected.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to user accounts and potential data exfiltration through cross-site scripting attacks. The impact can extend beyond individual user accounts, leading to broader organizational risks if sensitive data is compromised.
Organizations using Cianet ONU GW24AC should assess their exposure and implement necessary security controls to mitigate the risks associated with this vulnerability. Given the low complexity of the attack and its potential consequences, it is imperative to address this vulnerability promptly.
The urgency for remediation is classified as medium, indicating that while immediate action is necessary, it may be integrated into the upcoming patch cycles instead of requiring an emergency response.
