CVE-2023-5058 identifies a high-severity vulnerability in Phoenix SecureCore Technology 4, characterized by improper input validation during the processing of user-supplied splash screens during system boot. This vulnerability allows attackers to potentially execute arbitrary code or launch denial-of-service attacks. The CVSS score of 7.8 reflects the significant risk associated with this flaw, necessitating swift action from organizations to safeguard their systems.
Given the local attack vector and low complexity, the exploitability of this vulnerability is high. Attackers require only low privileges and do not need user interaction to trigger the vulnerability. The potential impacts include significant confidentiality, integrity, and availability risks, underscoring the urgency for organizations to address this vulnerability promptly.
Organizations should prioritize patching immediately. Failure to do so may leave systems exposed to significant threats that could compromise sensitive data and disrupt operations.
As of now, there are no public exploits or proof of concept available, but the high CVSS score indicates that this vulnerability should be treated with utmost seriousness.
Vulnerability Details
The vulnerability is characterized as improper input validation, which falls under the Common Weakness Enumeration (CWE-20). The CVSS version 3.1 vector string is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating that the attack vector is local, with low complexity and low privilege requirements.
The affected product is Phoenix SecureCore Technology version 4. The vulnerability was published on December 7, 2023, and has been analyzed thoroughly.
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of input, particularly in the handling of user-supplied splash screens during system boot. This flaw can lead to arbitrary code execution if an attacker manages to manipulate the input during this critical phase of the system's operation.
The attack vector is local, meaning that an attacker must have physical access to the system to exploit this vulnerability. The attack complexity is low, indicating that exploiting this vulnerability does not require advanced skills or significant resources.
In terms of required privileges, the attacker must have low privileges, allowing them to execute code that could compromise system security. User interaction is not required, which further increases the risk.
The confidentiality, integrity, and availability impacts are all rated as high, which means that successful exploitation can lead to severe consequences for the organization.
Risk & Impact Analysis
Risk to organizations includes significant potential for unauthorized access and control over affected systems, resulting in data breaches or system outages. The vulnerability’s impact could extend beyond individual systems, potentially affecting broader network security.
As the CVSS score indicates, organizations face a high risk due to the combination of local attack vector and the low complexity of exploitation. The urgency for remediation cannot be overstated, as delays may result in severe disruption and financial loss.
