CVE-2025-21103 is a high-severity vulnerability affecting the Dell NetWorker Management Console, specifically in versions 19.11 through 19.11.0.3 and versions prior to 19.10.0.7. The vulnerability arises from an improper neutralization of server-side input, which could allow an unauthenticated attacker with local access to potentially execute arbitrary code on the server. This issue has been analyzed and is categorized as critical for organizations using affected versions.
With a CVSS score of 7.8, this vulnerability poses a significant risk to organizations, as it can compromise confidentiality, integrity, and availability. Attackers may leverage this vulnerability to gain unauthorized control over the affected systems, leading to severe operational disruptions and data breaches. Organizations should prioritize patching immediately to mitigate these risks.
As of now, there are no known exploits, and the vulnerability is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential for exploitation remains high due to the nature of the vulnerability. Organizations should address this vulnerability in their priority patch cycle.
The urgency for remediation is further underscored by the fact that the vulnerability requires local access to exploit, emphasizing the need for robust physical and network security measures to prevent unauthorized access to sensitive systems.
In conclusion, CVE-2025-21103 reflects the ongoing need for vigilance in managing vulnerabilities, particularly those that have the capacity to allow attackers to execute arbitrary code on vulnerable systems.
Vulnerability Details
The official description of CVE-2025-21103 states that 'Dell NetWorker Management Console, version(s) 19.11 through 19.11.0.3 & Versions prior to 19.10.0.7 contain(s) an improper neutralization of server-side vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability and run arbitrary code on the server.' This vulnerability is classified under CWE-97, which refers to Improper Neutralization of Special Elements used in an Expression Language (such as SQL Injection).
The CVSS score of 7.8 indicates a high severity level, suggesting that successful exploitation could lead to significant impacts on the confidentiality, integrity, and availability of the affected systems. The attack vector is classified as LOCAL, with a low attack complexity, no privileges required, and user interaction needed for exploitation.
This vulnerability affects the Dell NetWorker product specifically, with the published date noted as February 17, 2025.
Technical Analysis
The root cause of CVE-2025-21103 is found in the improper handling of input on the server side, allowing attackers to manipulate server commands through crafted requests. The attack vector is local, meaning attackers must have physical or local network access to the vulnerable system. The attack complexity is low, with no specific privileges required to execute the attack, although user interaction is necessary.
Exploitation would likely involve an attacker gaining access to the system and leveraging the vulnerability to run arbitrary code, potentially leading to full control of the system. The impact of a successful exploitation would severely affect confidentiality, integrity, and availability, as the attacker could manipulate or leak sensitive data.
Risk & Impact Analysis
Risk to organizations includes unauthorized access, data loss, and operational disruption. The potential for an attacker to run arbitrary code on the server could lead to significant security breaches, making it imperative for organizations to address this vulnerability promptly. The blast radius is considerable, as the vulnerability affects all systems running the specified versions of the Dell NetWorker Management Console.
Based on the CVSS score, urgency for remediation is classified as high. Organizations should ensure that they update their systems to the latest versions immediately to mitigate this vulnerability and secure their environments.
