EUVD-2025-33745

Comprehensive Technical Analysis of EUVD-2025-33745

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-33745 pertains to the "Simple Car Rental System 1.0" developed by code-projects. This system has a critical permission bypass issue that allows low-privilege users to forge high-privilege sessions and perform sensitive operations. The CVSS (Common Vulnerability Scoring System) base score of 9.9 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Privileges Required (PR): Low (L) - The attacker needs low-level privileges to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required for the attack to succeed.
• Scope (S): Changed (C) - The vulnerability affects a different security authority.
• Confidentiality (C): High (H) - The vulnerability results in a complete loss of confidentiality.
• Integrity (I): High (H) - The vulnerability results in a complete loss of integrity.
• Availability (A): High (H) - The vulnerability results in a complete loss of availability.

Given these metrics, the vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected system.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector involves network-based exploitation where an attacker with low-level privileges can escalate their permissions to perform high-privilege operations. Potential exploitation methods include:

• Session Forging: Attackers may manipulate session tokens or cookies to impersonate high-privilege users.
• API Abuse: Exploiting poorly secured APIs to perform unauthorized actions.
• SQL Injection: If the system uses SQL databases, attackers might exploit SQL injection vulnerabilities to gain unauthorized access.
• Cross-Site Request Forgery (CSRF): Attackers could trick users into performing actions they did not intend to perform.

3. Affected Systems and Software Versions

The vulnerability specifically affects "Simple Car Rental System 1.0" developed by code-projects. All installations of this software version are potentially at risk. It is crucial to identify and update all instances of this software to mitigate the risk.
