Comprehensive Technical Analysis of EUVD-2025-36157
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2025-36157 pertains to an SQL injection flaw in the DRED virtual campus platform. This vulnerability allows an attacker to manipulate the database by sending a specially crafted POST request using the ‘buscame’ parameter in the ‘/catalogo_c/catalogo.php’ endpoint. The CVSS (Common Vulnerability Scoring System) base score of 9.3 indicates a critical severity level. The vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N breaks down as follows:
- AV:N (Attack Vector: Network): The vulnerability is exploitable over the network.
- AC:L (Attack Complexity: Low): The attack requires minimal skill or resources.
- AT:N (Attack Technique: Network): The attack involves network-based techniques.
- PR:N (Privileges Required: None): No privileges are required to exploit the vulnerability.
- UI:N (User Interaction: None): No user interaction is required.
- VC:H (Vulnerability Consequence: High): The impact on confidentiality is high.
- VI:H (Vulnerability Impact: High): The impact on integrity is high.
- VA:H (Vulnerability Availability: High): The impact on availability is high.
- SC:N (Scope Change: None): The vulnerability does not change the security scope.
- SI:N (Scope Impact: None): The impact on the security scope is none.
- SA:N (Scope Availability: None): The impact on the availability scope is none.
Given these metrics, the vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected systems.
