Insecure direct object reference (IDOR) vulnerability in Anapi Group's h6web allows an authenticated attacker to access other users' information by making a POST request and modifying the “pkrelated” parameter in the “/h6web/ha_datos_hermano.php” endpoint to refer to another user. This vulnerability can lead to unauthorized access and impersonation, enabling attackers to execute requests with the privileges of the impersonated user. Given the severity of this vulnerability, organizations should prioritize patching immediately.
The CVSS score of 9.1 indicates a critical severity level, emphasizing the urgent need for organizations to implement effective remediation strategies. The potential impact on confidentiality is high, with attackers able to access sensitive user information.
This vulnerability reflects a significant risk to organizations using the affected product, as it can lead to data breaches and loss of trust among users. Immediate action is required to secure the application and protect user data.
As there is currently no known public exploit or proof of concept, organizations should proactively address this vulnerability by applying the necessary patches and reviewing their security posture.
Vulnerability Details
The vulnerability allows an attacker to exploit insecure direct object references, specifically through the modification of the “pkrelated” parameter in the specified endpoint. The vulnerability is classified as CWE-639, indicating a weakness in access control mechanisms. The official description details how this vulnerability can be exploited to gain unauthorized access to user data.
The vulnerability affects all versions of Anapi Group's h6web prior to the patch. Organizations are urged to review their systems for this vulnerability and take appropriate actions.
Technical Analysis
The root cause of this vulnerability is the failure to properly validate user input, allowing attackers to manipulate parameters and access unauthorized resources. The attack vector is network-based, and the complexity of the attack is low, requiring only basic skills to execute successfully.
The privileges required for exploitation are low, meaning an authenticated user can execute the attack without special permissions. There is no user interaction required to exploit this vulnerability, making it particularly dangerous.
The impacts of this vulnerability include high confidentiality impact, as sensitive user information can be accessed, and low integrity and availability impacts, as the primary concern is unauthorized access rather than data manipulation or service disruption.
Risk & Impact Analysis
Risk to organizations includes potential data breaches and compromised user accounts. The ability for attackers to impersonate other users significantly increases the blast radius of this vulnerability, potentially affecting a large number of users and leading to trust issues.
Given the critical severity of this vulnerability, organizations should address it in priority patch cycles. The longer this vulnerability remains unaddressed, the greater the risk of exploitation.
With a CVSS score of 9.1, this vulnerability is a high priority for remediation. Organizations need to evaluate their security controls and ensure that they are robust enough to prevent such vulnerabilities.
