Vulnerability Details
The vulnerability in question affects the Excitel Broadband Private my Excitel App version 3.13.0 on Android. The vulnerability allows for improper restriction of excessive authentication attempts via the One-Time Password Handler component. This is indicative of potential weaknesses in the app’s user authentication process, which could be exploited by attackers to gain unauthorized access.
The CVSS score of 5.1 categorizes this as a medium severity vulnerability, with a low attack complexity. The attack vector is classified as adjacent, meaning that an attacker must be on the same local network to exploit this vulnerability. There are no impacts on confidentiality, integrity, or availability, which may limit the immediate risk but does not eliminate the need for remediation.
The vulnerability is associated with CWE-307 (Improper Restriction of Excessive Authentication Attempts) and CWE-799 (Improper Control of Interaction Frequency). These classifications highlight the underlying issues related to authentication mechanisms within the application.
Technical Analysis
The root cause of this vulnerability stems from insufficient controls on the One-Time Password Handler, which fails to limit the number of authentication attempts. This flaw allows attackers to perform brute-force attacks against user accounts, significantly increasing the risk of unauthorized access.
The attack vector for this vulnerability is classified as adjacent, meaning that the attacker must be on the same local network as the target device. The attack complexity is low, indicating that an attacker does not need advanced skills to exploit this vulnerability. Moreover, the privileges required are low, allowing any user with access to the network to attempt exploitation.
User interaction is not required for exploitation, which further amplifies the risk. The vulnerability impacts confidentiality with a low level, as an attacker could potentially access sensitive data through unauthorized means.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant due to the potential for unauthorized access to user accounts. The improper restriction on authentication attempts can lead to a situation where attackers can brute force their way into accounts, especially if users have weak passwords.
The urgency for organizations to address this vulnerability is highlighted by its medium CVSS score. Given the increasing sophistication of attackers and the commonality of brute-force attacks, this issue should be rated as high priority in any patch management cycle.
Organizations that have deployed the affected version of the my Excitel App must prioritize remediation efforts to mitigate the risk. The potential blast radius includes all users of the application, making the impact widespread across user accounts.
