CVE-2024-1839

Comprehensive Technical Analysis of CVE-2024-1839

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-1839 CISA Vulnerability Name: CVE-2024-1839 CVSS Score: 10

The vulnerability in question pertains to the Intrado 911 Emergency Gateway login form, which is susceptible to an unauthenticated blind time-based SQL injection. This type of vulnerability is particularly severe due to its potential to allow unauthenticated remote attackers to execute arbitrary SQL commands, exfiltrate sensitive data, or manipulate the database.

Severity Evaluation:

• CVSS Score: 10 (Critical)
• Impact: High
• Exploitability: High

The CVSS score of 10 indicates the highest level of severity, reflecting the critical nature of the vulnerability. The potential for unauthenticated remote exploitation significantly increases the risk, as it does not require any prior access to the system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The attacker does not need any credentials to exploit the vulnerability.
• Blind Time-Based SQL Injection: The attacker can inject SQL commands that cause a delay in the database response, allowing them to infer information about the database structure and contents.

Exploitation Methods:

• SQL Injection: The attacker can craft SQL queries that exploit the vulnerability in the login form. For example, they might use time-based functions like SLEEP() to introduce delays and deduce the structure of the database.
• Data Exfiltration: By manipulating SQL queries, the attacker can extract sensitive information such as user credentials, personal data, or operational details.
• Database Manipulation: The attacker can alter database entries, potentially disrupting the functionality of the 911 Emergency Gateway.

3. Affected Systems and Software Versions

Affected Systems:

• Intrado 911 Emergency Gateway

Software Versions:
