Comprehensive Technical Analysis of EUVD-2025-205297
1. Vulnerability Assessment and Severity Evaluation
The vulnerability in the Telenium Online Web Application, identified as EUVD-2025-205297, involves a Perl script used to load the login page. Due to improper input validation, this script is susceptible to arbitrary Perl code injection via crafted HTTP requests, leading to remote code execution (RCE) on the server.
Severity Evaluation:
- Base Score: 9.3 (CVSS 4.0)
- 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
The high base score of 9.3 indicates a critical vulnerability. The attack vector (AV:N) is network-based, requiring low complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H), making this a severe threat.
