CVE-2025-38743 Vulnerability Summary

CVE-2025-38743: Dell iDRAC Service Module (iSM), versions prior to 6.0.3.0, contains a Buffer Access with Incorrect Length Value vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Code execution and Elevation of privileges.

Assessing the Risk of CVE-2025-38743

Access Complexity Graph

The exploitability of CVE-2025-38743 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-38743

CVE-2025-38743 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-38743, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2025-38743, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2025-38743 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: High
    CVE-2025-38743 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
  • Availability: High
    CVE-2025-38743 can disrupt system operations, potentially causing complete denial of service (DoS).

CWE Common Weakness Enumeration

CWE-805

CAPEC Common Attack Pattern Enumeration and Classification

  • Overflow Buffers CAPEC-100 Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an adversary. As a consequence, an adversary is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the adversaries' choice.
  • SOAP Array Overflow CAPEC-256 An attacker sends a SOAP request with an array whose actual length exceeds the length indicated in the request. If the server processing the transmission naively trusts the specified size, then an attacker can intentionally understate the size of the array, possibly resulting in a buffer overflow if the server attempts to read the entire data set into the memory it allocated for a smaller array.
