EUVD-2025-20139

Comprehensive Technical Analysis of EUVD-2025-20139

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-20139 allows remote attackers to execute arbitrary code within the context of the vulnerable service process. The CVSS (Common Vulnerability Scoring System) base score of 9.5 indicates a critical severity level. The CVSS vector breakdown is as follows:

• AV:N (Network Vector): The vulnerability is exploitable over the network.
• AC:H (High Complexity): Exploiting the vulnerability requires a high level of skill or specific conditions.
• AT:N (No Authentication): No authentication is required to exploit the vulnerability.
• PR:N (No Privileges Required): No special privileges are needed to exploit the vulnerability.
• UI:N (No User Interaction): No user interaction is required to exploit the vulnerability.
• VC:H, VI:H, VA:H (High Confidentiality, Integrity, and Availability Impact): Successful exploitation results in high impact on confidentiality, integrity, and availability.
• SC:H, SI:H, SA:H (High Scope Change): The vulnerability can affect other components beyond the initial scope.
• S:P (Partial Scope Change): The vulnerability affects resources beyond the security scope managed by the security authority of the vulnerable component.
• AU:Y (Authentication Required): Authentication is required for the vulnerability to be exploited.
• R:I (Integrity Required): Integrity is required for the vulnerability to be exploited.
• V:C (Confidentiality Required): Confidentiality is required for the vulnerability to be exploited.
• RE:L (Low Remediation Level): The vulnerability is relatively easy to remediate.
• U:Red (Reduced): The vulnerability is reduced in scope.

2. Potential Attack Vectors and Exploitation Methods

Given the high complexity (AC:H) and the requirement for authentication (AU:Y), potential attack vectors could include:

• Network-Based Attacks: Exploiting the vulnerability over the network without requiring user interaction.
• Phishing and Social Engineering: Tricking users into providing authentication credentials that can be used to exploit the vulnerability.
• Malicious Insiders: Individuals with legitimate access who exploit the vulnerability for malicious purposes.

Exploitation methods may involve crafting specific network packets or commands that trigger the vulnerability, leading to arbitrary code execution.

3. Affected Systems and Software Versions

The vulnerability affects the following systems and software versions:

• Symantec IT Management Suite: Versions 8.6.x, 8.7.x, and 8.8.
