Comprehensive Technical Analysis of EUVD-2024-19498

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2024-19498 is a command injection flaw affecting web components of Ivanti Connect Secure and Ivanti Policy Secure. This vulnerability allows an authenticated administrator to execute arbitrary commands on the appliance by sending specially crafted requests. The CVSS (Common Vulnerability Scoring System) base score of 9.1 indicates a critical severity level. The CVSS vector CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/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): High (H) - The attacker must be an authenticated administrator.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Changed (C) - The vulnerability affects a different security scope.
• Confidentiality (C): High (H) - Complete loss of confidentiality.
• Integrity (I): High (H) - Complete loss of integrity.
• Availability (A): High (H) - Complete loss of availability.

2. Potential Attack Vectors and Exploitation Methods

Given the nature of the vulnerability, potential attack vectors include:

• Authenticated Administrator Exploitation: An attacker with administrative privileges can craft malicious requests to execute arbitrary commands on the appliance.
• Internal Threats: Insider threats where an authenticated administrator with malicious intent exploits the vulnerability.
• Compromised Credentials: If an administrator's credentials are compromised, an external attacker could exploit this vulnerability.

Exploitation methods may involve:

• Command Injection: Crafting HTTP requests that include malicious commands to be executed on the server.
• Script Automation: Using automated scripts to send specially crafted requests to the vulnerable web components.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of Ivanti Connect Secure and Ivanti Policy Secure:

• Ivanti Connect Secure: Versions 9.x and 22.x
• Ivanti Policy Secure: Versions 9.x and 22.x

Specific product versions mentioned include:

• ICS: Versions 9.1R18 ≤9.1R18 and 22.6R2 ≤22.6R2
• IPS: Versions 9.1R18 ≤9.1R18, 22.6R1 ≤22.6R1
