Description

An issue was discovered in the A4N (Aremis 4 Nomad) application 1.5.0 for Android. It possesses an authentication mechanism; however, some features do not require any token or cookie in a request. Therefore, an attacker may send a simple HTTP request to the right endpoint, and obtain authorization to retrieve application data.

Technical Analysis

CVE-2022-34908 is a high-severity vulnerability identified in the A4N (Aremis 4 Nomad) Android application version 1.5.0. The core issue stems from an improper authentication mechanism within the app. Although the application implements authentication, certain features or endpoints do not require any authentication tokens or cookies to be included in HTTP requests. This design flaw allows an attacker to send simple HTTP requests directly to these unprotected endpoints and gain unauthorized access to application data. The vulnerability is classified under CWE-306, which relates to missing or insufficient authentication. The CVSS 3.1 base score is 8.2, reflecting a high impact primarily due to the ability to access sensitive data without any authentication, with no user interaction or privileges required, and the attack vector being network-based (remote). The vulnerability affects confidentiality significantly, with limited impact on integrity and no impact on availability. No known exploits have been reported in the wild, and no patches or vendor advisories are currently available. The lack of authentication on certain endpoints represents a critical security oversight that could be exploited by attackers to harvest sensitive information from the application, potentially leading to data breaches or further attacks leveraging the exposed data.

Potential Impact

For European organizations using the A4N application, this vulnerability poses a significant risk to the confidentiality of sensitive data managed or accessed through the app. Unauthorized data retrieval could lead to exposure of personal, corporate, or operational information, undermining privacy and compliance with regulations such as the GDPR. The breach of confidentiality could damage organizational reputation, result in regulatory fines, and facilitate further targeted attacks if sensitive data is leveraged by threat actors. Given that the vulnerability requires no authentication or user interaction, attackers can remotely exploit it with ease, increasing the likelihood of automated or opportunistic attacks. Organizations relying on this application for critical business functions or handling sensitive data should consider the risk of data leakage and potential operational disruptions caused by exploitation of this flaw.

Mitigation Recommendations

Given the absence of official patches or vendor advisories, European organizations should implement immediate compensating controls. These include: 1) Conducting a thorough audit of the A4N application usage within the organization to identify all instances and versions deployed. 2) Restricting network access to the application endpoints by implementing firewall rules or network segmentation to limit exposure to trusted users and devices only. 3) Monitoring network traffic for unusual or unauthorized HTTP requests targeting the application endpoints, using intrusion detection or prevention systems. 4) Employing application-layer gateways or reverse proxies that enforce authentication before forwarding requests to the backend application. 5) Engaging with the application vendor or developer to request timely patches or updates addressing the authentication bypass. 6) Educating users about the risks and encouraging vigilance for suspicious application behavior. 7) Considering temporary discontinuation or replacement of the application if critical data exposure risk cannot be mitigated effectively until a patch is available.
