1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2022-36975 CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for remote attackers to bypass authentication mechanisms, which can lead to unauthorized access and potential data breaches. The vulnerability is classified as critical because it allows for the execution of SQL queries composed from user-supplied strings, indicating a SQL injection flaw.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: The vulnerability can be exploited remotely, meaning attackers do not need physical access to the affected systems.
• SQL Injection: The specific flaw within the ProfileDaoImpl class allows attackers to inject malicious SQL queries through crafted requests.

Exploitation Methods:

• Crafted Requests: Attackers can send specially crafted HTTP requests to the affected system, which can trigger the execution of SQL queries.
• Authentication Bypass: By exploiting the SQL injection flaw, attackers can bypass authentication mechanisms, gaining unauthorized access to the system.

3. Affected Systems and Software Versions

Affected Software:

• Ivanti Avalanche 6.3.2.3490

Affected Systems:

• Any system running the specified version of Ivanti Avalanche is vulnerable to this exploit. This includes enterprise environments where Ivanti Avalanche is used for mobile device management (MDM).

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to the latest version of Ivanti Avalanche that addresses this vulnerability. According to the release notes, version 6.3.4 includes the necessary fixes.
• Network Segmentation: Isolate affected systems from the broader network to limit potential attack vectors.
• Monitoring: Implement enhanced monitoring for suspicious activities, especially around authentication mechanisms and SQL query execution.
