Executive Summary

CVE-2018-25410 is an SQL injection vulnerability in SIM-PKH version 2.4.1. It occurs in the 'id' parameter of the media.php file, specifically when accessed with the parameters module=pengurus and act=editpengurus. Authenticated attackers can inject malicious SQL code through this parameter by sending crafted GET requests, allowing them to execute arbitrary SQL queries on the backend database.

This injection enables attackers to extract sensitive database information such as usernames, database names, and version details by leveraging SQL UNION statements.

Compliance Impact

The SQL injection vulnerability in SIM-PKH 2.4.1 allows attackers to extract sensitive database information such as usernames, database names, and version details. This unauthorized access to sensitive data could lead to violations of data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access and breaches.

By enabling attackers to retrieve sensitive information through SQL injection, the vulnerability increases the risk of data breaches and non-compliance with standards that mandate strict controls on data confidentiality and integrity.

Mitigation Strategies

To mitigate the SQL injection vulnerability in SIM-PKH 2.4.1, immediate steps include restricting access to the /admin/media.php endpoint, especially the parameters module=pengurus and act=editpengurus, to only trusted authenticated users.

Additionally, applying input validation and sanitization on the 'id' parameter to prevent injection of malicious SQL code is critical.

If available, upgrading to a fixed or patched version of SIM-PKH beyond 2.4.1 is recommended to fully resolve the issue.

Monitoring and logging access to the vulnerable endpoint can help detect potential exploitation attempts.

Impact Analysis

The vulnerability allows attackers to gain unauthorized access to sensitive database information, including usernames and database details. This can lead to further exploitation such as unauthorized data access, data leakage, or manipulation of database contents.

Since the attacker can execute arbitrary SQL commands, it may also facilitate privilege escalation or compromise of the entire application backend, potentially impacting the confidentiality and integrity of your data.

Detection Guidance

This vulnerability can be detected by sending crafted GET requests to the vulnerable endpoint and observing the response for SQL injection behavior.

Specifically, you can test the /admin/media.php endpoint with parameters module=pengurus and act=editpengurus, injecting SQL UNION statements into the 'id' parameter.

An example command using curl to test for the vulnerability is:

• curl "http://[target]/admin/media.php?module=pengurus&act=editpengurus&id=-1' UniOn(sELect 0x283129,CONCAT(0x203a20,User(),DatabaSE(),VErsiON()),0x283329)--+"

If the response contains database user, database name, or version information, it indicates the presence of the SQL injection vulnerability.
