CVE-2023-33877 is classified as a low-severity vulnerability affecting Intel RealSense 450 FA firmware, specifically version 0.25.0. This vulnerability allows an out-of-bounds write, potentially enabling an authenticated user to escalate privileges through local access. While the CVSS base score is 3.3, indicating a low severity level, it is crucial for organizations to address this vulnerability proactively.
Given the nature of this vulnerability, risk to organizations includes potential unauthorized access and manipulation of sensitive resources. Organizations should prioritize patching immediately, even though the overall impact seems limited due to the low severity designation.
The vulnerability has not been confirmed to be actively exploited in the wild, and there are no known public exploits available at this time. However, organizations that utilize the affected Intel RealSense 450 FA firmware should remain vigilant and ensure their systems are updated to mitigate any potential risks.
Patching efforts should be made as part of routine maintenance, especially for systems operating in sensitive environments. Inadequate patching may expose systems to unnecessary risks.
Vulnerability Details
The official description of CVE-2023-33877 states that an out-of-bounds write in some Intel(R) RealSense(TM) ID software for Intel(R) RealSense(TM) 450 FA in version 0.25.0 may allow an authenticated user to potentially enable escalation of privilege via local access. The vulnerability falls under the CWE-787 classification, which pertains to out-of-bounds writes.
The severity of this vulnerability has been scored under the CVSS v3.1 as follows: Attack Vector: LOCAL, Attack Complexity: LOW, Privileges Required: LOW, User Interaction: NONE, Confidentiality Impact: NONE, Integrity Impact: LOW, Availability Impact: NONE. The base score assigned by the NVD is 7.8, classifying it as high severity, whereas Intel's assessment leads to a classification of low severity with a score of 3.3.
Organizations running affected versions of the Intel RealSense 450 FA firmware should ensure they are informed about the patch status. The vulnerability affects all versions prior to the vendor patch. The official advisory can be found on Intel's security center.
Technical Analysis
The root cause of CVE-2023-33877 is attributed to an out-of-bounds write, which occurs when a program writes data outside the boundaries of allocated memory. This can lead to unpredictable behavior, including crashing the program or, in this case, potentially allowing privilege escalation.
The attack vector is local, meaning that an attacker must have access to the local system to exploit this vulnerability. The attack complexity is low, as it does not require advanced skills or techniques. Additionally, the privileges required to exploit this vulnerability are also low, allowing authenticated users to trigger the flaw without needing elevated access.
No user interaction is required to exploit this vulnerability, which increases the risk of an attack. The impact on confidentiality is none, while the integrity impact is low, meaning that an attacker could potentially alter data, albeit with limited scope. There is no availability impact associated with this vulnerability.
Risk & Impact Analysis
In real-world deployments, the risk associated with CVE-2023-33877 includes the potential for unauthorized escalation of privileges, which could lead to broader system exploitation. Given that the vulnerability is classified as low severity, organizations might perceive the risk as manageable; however, even low-severity vulnerabilities can create pathways for attackers to gain further access.
The blast radius of this vulnerability is relatively contained due to its local attack vector and the requirement for authenticated access. However, its potential to allow privilege escalation means that organizations should not underestimate the importance of remediation.
The urgency to address this vulnerability is moderate, considering the CVSS score of 7.8 from NVD, which suggests that organizations should schedule remediation as part of their routine patch management processes.
