Comprehensive Technical Analysis of EUVD-2025-202345
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-202345 affects ColdFusion versions 2025.4, 2023.16, 2021.22, and earlier. It is classified as an Improper Input Validation vulnerability, which can lead to a security feature bypass. The CVSS (Common Vulnerability Scoring System) base score of 9.1 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N breaks down as follows:
- Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
- Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
- Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
- User Interaction (UI): None (N) - No user interaction is required for exploitation.
- Scope (S): Unchanged (U) - The vulnerability does not affect other systems or components.
- Confidentiality (C): High (H) - The vulnerability allows unauthorized read access.
- Integrity (I): High (H) - The vulnerability allows unauthorized write access.
- Availability (A): None (N) - The vulnerability does not affect the availability of the system.
2. Potential Attack Vectors and Exploitation Methods
Given the nature of the vulnerability, potential attack vectors include:
- Network-Based Attacks: Since the attack vector is network-based, an attacker could exploit this vulnerability remotely without needing physical access to the system.
- Automated Scripts: Attackers could use automated scripts to scan for vulnerable ColdFusion installations and exploit the vulnerability en masse.
- Phishing and Social Engineering: Although user interaction is not required, attackers might still use phishing or social engineering to gain initial access to the network where ColdFusion is deployed.
Exploitation methods could involve:
- Crafted Inputs: Sending specially crafted inputs to the ColdFusion server to bypass security measures.
- Exploit Kits: Using pre-built exploit kits that automate the process of identifying and exploiting the vulnerability.
3. Affected Systems and Software Versions
The affected systems include any server running ColdFusion versions 2025.4, 2023.16, 2021.22, and earlier. This encompasses a wide range of enterprise environments where ColdFusion is used for web application development and deployment.
