EUVD-2025-38157

Comprehensive Technical Analysis of EUVD-2025-38157

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability identified as EUVD-2025-38157 affects the oobabooga text-generation-webui software. Specifically, it involves the trust_remote_code parameter in the load endpoint, which fails to properly validate user-supplied input. This flaw allows remote attackers to execute arbitrary code without requiring authentication.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.8, which is classified as critical. The CVSS vector CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high severity score underscores the critical nature of the vulnerability, as it can be exploited remotely with low complexity and without any user interaction or privileges.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Code Execution (RCE): An attacker can send a specially crafted request to the load endpoint with a malicious trust_remote_code parameter, leading to arbitrary code execution.
• Unauthenticated Access: The vulnerability does not require authentication, making it easier for attackers to exploit.

Exploitation Methods:

• Crafting Malicious Input: An attacker can craft a payload that exploits the lack of validation in the trust_remote_code parameter.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable installations and exploit them en masse.

3. Affected Systems and Software Versions

Affected Software:

• Product: text-generation-webui
• Version: 2.5
• Vendor: oobabooga

Affected Systems:

• Any system running the vulnerable version of text-generation-webui is at risk. This includes servers, cloud instances, and any other environments where the software is deployed.
