Executive Summary

CVE-2018-25206 is a high-severity SQL injection vulnerability found in KomSeo Cart version 1.3. It exists in the edit.php file through the 'my_item_search' parameter. Attackers can exploit this flaw by sending specially crafted POST requests containing malicious SQL payloads.

The vulnerability allows attackers to inject arbitrary SQL commands using techniques such as boolean-based blind SQL injection and error-based SQL injection. This enables them to extract sensitive information from the underlying database by manipulating the search input that is not properly sanitized.

Detection Guidance

This SQL injection vulnerability in KomSeo Cart 1.3 can be detected by sending crafted POST requests to the '/phpcart/edit.php' endpoint, specifically targeting the 'my_item_search' parameter with malicious SQL payloads.

Two common techniques to test for this vulnerability include boolean-based blind SQL injection and error-based SQL injection.

• Boolean-based blind SQL injection test payload example: my_item_search=-5021' OR 3148=3148#
• Error-based SQL injection test payload example: my_item_search=test' AND (SELECT 8609 FROM(SELECT COUNT(*),CONCAT(0x7170787671,(SELECT (ELT(8609=8609,1))),0x7178707071,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.PLUGINS GROUP BY x)a)-- voqa

These payloads can be sent using tools like curl or specialized SQL injection testing tools to observe if the application behaves abnormally or returns database error messages, indicating the presence of the vulnerability.

Compliance Impact

The SQL injection vulnerability in KomSeo Cart 1.3 allows attackers to extract sensitive database information by injecting malicious SQL commands. This unauthorized access to sensitive data can lead to data breaches, which may violate compliance requirements of common standards and regulations such as GDPR and HIPAA that mandate protection of personal and sensitive information.

Specifically, the ability to extract sensitive information through this vulnerability could result in exposure of personal data, thereby compromising confidentiality and potentially leading to regulatory penalties or legal consequences for failing to adequately protect user data.

Mitigation Strategies

To mitigate the SQL injection vulnerability in KomSeo Cart 1.3, immediate steps include restricting or disabling the vulnerable 'my_item_search' parameter in the edit.php script to prevent malicious POST requests.

Additionally, applying input validation and sanitization on the 'my_item_search' parameter to ensure that SQL commands cannot be injected is critical.

If possible, update or patch the KomSeo Cart application to a version where this vulnerability is fixed.

As a temporary measure, consider implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting the 'my_item_search' parameter.
