Executive Summary

CVE-2018-25399 is a high-severity SQL injection vulnerability found in the Open ISES Project version 3.30A or earlier. It exists in the nearby.php file, where unauthenticated attackers can inject malicious SQL code through the tick_lat and tick_lng parameters.

By sending specially crafted GET requests with malicious SQL payloads, attackers can execute arbitrary SQL queries on the database.

This allows attackers to extract sensitive information such as usernames, database names, and version details from the database.

Impact Analysis

This vulnerability can lead to unauthorized access to sensitive database information, including usernames, database names, and version details.

Attackers can manipulate SQL queries to extract or potentially alter data, which may compromise the integrity and confidentiality of your database.

Since the vulnerability allows execution of arbitrary SQL commands without authentication, it poses a significant risk of data breach and database compromise.

Detection Guidance

This vulnerability can be detected by monitoring for suspicious GET requests to the nearby.php file that include unusual or crafted SQL payloads in the tick_lat and tick_lng parameters.

One approach is to use network traffic inspection tools or web server logs to identify requests containing SQL injection patterns targeting these parameters.

For example, you can use command-line tools like curl or wget to test the endpoint with crafted payloads to see if the system is vulnerable.

• curl "http://target/nearby.php?tick_lat=1' OR '1'='1&tick_lng=1' OR '1'='1"
• grep -i "tick_lat" /var/log/apache2/access.log | grep -E "(\' OR \'1\'=\'1|UNION|SELECT)"

Additionally, using vulnerability scanners that support SQL injection detection against the nearby.php endpoint focusing on tick_lat and tick_lng parameters can help identify the issue.

Mitigation Strategies

Immediate mitigation steps include restricting access to the vulnerable nearby.php endpoint and applying input validation or sanitization on the tick_lat and tick_lng parameters to prevent SQL injection.

If possible, update the Open ISES Project software to a version where this vulnerability is fixed or apply patches provided by the vendor.

As a temporary measure, consider implementing a Web Application Firewall (WAF) to block malicious SQL injection attempts targeting these parameters.

Monitoring logs for suspicious activity and blocking IP addresses that attempt exploitation can also reduce risk.

Compliance Impact

The SQL injection vulnerability in the Open ISES Project 3.30A allows unauthenticated attackers to extract sensitive database information, including usernames and other data. This unauthorized access to sensitive information could lead to non-compliance with data protection regulations such as GDPR and HIPAA, which require safeguarding personal and sensitive data against unauthorized access and breaches.

By enabling attackers to execute arbitrary SQL queries and potentially access or manipulate sensitive data, the vulnerability increases the risk of data breaches and exposure of protected information, which are critical compliance concerns under these standards.
