CVE-2024-33051: High Vulnerability in Qualcomm Firmware

CVE-2024-33051 is a high-severity vulnerability discovered in Qualcomm's firmware that allows for a transient denial-of-service (DoS) condition. The vulnerability arises due to inadequate checks for the Information Element (IE) length while processing the TIM IE from the beacon frame. This flaw can lead to significant availability impact, making systems susceptible to service interruptions.

The CVSS score for this vulnerability is 7.5, indicating a high level of severity. The attack vector is classified as network-based, with low attack complexity and no privileges required to exploit this vulnerability. User interaction is not necessary for an attack to be successful, which amplifies the potential risk to organizations.

Organizations are at risk of potential service disruptions, highlighting the urgency of addressing this vulnerability. Given the nature of the flaw, it's imperative for organizations to prioritize patching immediately.

As of now, there are no publicly available exploits confirmed for this vulnerability, but the absence of known exploitation does not diminish the need for prompt remediation. Security teams should ensure that all affected products are updated with the latest patches provided by Qualcomm.

Vulnerability Details

The official description of this vulnerability states: 'Transient DOS while processing TIM IE from beacon frame as there is no check for IE length.' The vulnerability is classified under CWE-125 and CWE-126, indicating issues related to improper handling of input data.

The vulnerability was published on September 2, 2024, and affects multiple Qualcomm firmware versions, including but not limited to 315 5G IoT firmware, 9206 LTE firmware, and APQ8017 firmware. Organizations using these products should assess their systems for vulnerability exposure.

Technical Analysis

The root cause of CVE-2024-33051 lies in the lack of validation for the length of the IE when processing TIM IE from the beacon frame. This oversight can lead to a denial-of-service condition, as attackers may exploit this weakness to disrupt services by sending specially crafted packets. The attack vector is network-based, meaning that an attacker can exploit the vulnerability remotely without needing to have physical access to the targeted device.

The attack complexity is low, as no special skills or resources are required to exploit this vulnerability. Additionally, the attack does not necessitate any user interaction, making it particularly dangerous. The impact on availability is significant, as successful exploitation can cause the affected system to become unresponsive, leading to service outages.

Risk & Impact Analysis

The deployment risk associated with this vulnerability is considerable, especially for organizations that rely on Qualcomm products for critical operations. The potential blast radius is broad, affecting multiple product lines and impacting service continuity. Given the CVSS score of 7.5, organizations should take immediate action to mitigate risks by prioritizing the application of patches.

Risk to organizations includes service interruptions that can lead to financial losses, reputational damage, and operational inefficiencies. The urgency of remediation is high, as the vulnerability can be exploited without prior authentication or user interaction.
