Comprehensive Technical Analysis of EUVD-2025-10355

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in EUVD-2025-10355 pertains to a privilege escalation issue in RUoYi v.4.8.0. The vulnerability allows a remote attacker to escalate privileges via the jobLogId parameter. The CVSS (Common Vulnerability Scoring System) base score of 9.8 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:H 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 complexity.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - The vulnerability has a high impact on confidentiality.
• Integrity (I): High (H) - The vulnerability has a high impact on integrity.
• Availability (A): High (H) - The vulnerability has a high impact on availability.

Given the high scores in confidentiality, integrity, and availability, this vulnerability poses a significant risk to systems running RUoYi v.4.8.0.
