CVE-2023-47295

Comprehensive Technical Analysis of CVE-2023-47295

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-47295 Description: A CSV injection vulnerability in NCR Terminal Handler v1.5.1 allows attackers to execute arbitrary commands via injecting a crafted payload into any text field that accepts strings. CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for remote code execution, which can lead to complete system compromise. The vulnerability's exploitability and the potential impact on confidentiality, integrity, and availability are significant.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• CSV Injection: Attackers can inject malicious payloads into text fields that accept strings. These payloads can be crafted to execute arbitrary commands when the CSV file is processed.
• Phishing: Attackers may use social engineering techniques to trick users into downloading and opening malicious CSV files.
• Supply Chain Attacks: Compromising upstream systems that generate CSV files for NCR Terminal Handler could also be a vector.

Exploitation Methods:

• Payload Crafting: Attackers can craft CSV files with embedded commands that are executed when the file is processed by the vulnerable software.
• Command Injection: The injected commands can include system commands, script execution, or any other malicious actions that the attacker intends to perform.

3. Affected Systems and Software Versions

Affected Software:

• NCR Terminal Handler v1.5.1

Affected Systems:

• Any system running the vulnerable version of NCR Terminal Handler.
• Systems that process CSV files generated or handled by NCR Terminal Handler v1.5.1.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest patches or updates provided by NCR for Terminal Handler.
• Input Validation: Implement strict input validation and sanitization for all text fields that accept strings.
• File Handling: Ensure that CSV files are processed in a secure manner, avoiding direct execution of commands embedded in the files.
