CVE-2019-10804 : Exploit Details and Defense Strategies

Serial-number versions up to 1.3.0 are vulnerable to command injection, allowing the execution of arbitrary commands.

Understanding CVE-2019-10804

This CVE identifies a security vulnerability in serial-number versions up to 1.3.0 that enables the execution of arbitrary commands.

What is CVE-2019-10804?

The vulnerability in serial-number versions up to 1.3.0 allows attackers to execute arbitrary commands due to improper validation of the "cmdPrefix" parameter within the serialNumber function.

The Impact of CVE-2019-10804

Exploitation of this vulnerability can lead to unauthorized execution of commands on affected systems, potentially resulting in data breaches, system compromise, and unauthorized access.

Technical Details of CVE-2019-10804

This section provides detailed technical information about the CVE-2019-10804 vulnerability.

Vulnerability Description

The vulnerability arises from the lack of validation of the "cmdPrefix" parameter within the serialNumber function, which is subsequently used by the "exec" function without proper verification.

Affected Systems and Versions

Product: serial-number
Vendor: n/a
Versions affected: All versions including 1.3.0

Exploitation Mechanism

Attackers can exploit this vulnerability by crafting malicious input that triggers the execution of unauthorized commands through the vulnerable "cmdPrefix" parameter.

Mitigation and Prevention

To address CVE-2019-10804 and enhance system security, follow these mitigation and prevention measures:

Immediate Steps to Take

Update serial-number to a patched version that includes proper validation of user input.
Implement input validation mechanisms to sanitize user-supplied data.
Monitor system logs for any suspicious command execution attempts.

Long-Term Security Practices

Conduct regular security audits and code reviews to identify and address potential vulnerabilities.
Train developers on secure coding practices to prevent similar vulnerabilities in the future.

Patching and Updates

Stay informed about security updates and patches released by the serial-number vendor.
Promptly apply patches to ensure that known vulnerabilities are mitigated.
