CVE-2019-25636: Zeeways Jobsite CMS SQLi Vulnerability

CVE-2019-25636 Overview

CVE-2019-25636 is a SQL Injection vulnerability affecting Zeeways Jobsite CMS. The vulnerability allows unauthenticated attackers to manipulate database queries by injecting SQL code through the id GET parameter. Attackers can send crafted requests to news_details.php, jobs_details.php, or job_cmp_details.php with malicious id values using GROUP BY and CASE statements to extract sensitive database information.

Critical Impact

Unauthenticated remote attackers can exploit this SQL injection vulnerability to extract sensitive database contents including user credentials, personal information, and potentially gain unauthorized access to the underlying system.

Affected Products

• Zeeways Jobsite CMS (all versions)

Technical Details for CVE-2019-25636

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists in Zeeways Jobsite CMS due to improper input validation and sanitization of user-supplied data. The vulnerable parameter is the id GET parameter which is used across multiple PHP files in the application.

The vulnerability is particularly dangerous because it requires no authentication, meaning any remote attacker with network access to the application can exploit it. The attack surface includes three PHP files: news_details.php, jobs_details.php, and job_cmp_details.php, all of which fail to properly sanitize the id parameter before incorporating it into SQL queries.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) when handling user-supplied input. The application directly concatenates the id GET parameter into SQL queries without sanitization, allowing attackers to inject arbitrary SQL code that gets executed by the database.

Attack Vector

The attack is network-based and can be executed remotely without any authentication or user interaction. Attackers craft malicious HTTP GET requests targeting the vulnerable PHP files with specially constructed id parameter values.

The exploitation technique involves using SQL GROUP BY and CASE statements within the injected payload to perform conditional extraction of database information. This is a form of blind SQL injection where the attacker can infer database contents based on the application's responses to different injected conditions.

Technical details and exploitation examples can be found in the Exploit-DB entry #46602 and the VulnCheck Security Advisory.

Detection Methods for CVE-2019-25636

Indicators of Compromise

• HTTP GET requests to news_details.php, jobs_details.php, or job_cmp_details.php containing SQL keywords in the id parameter
• Presence of SQL injection patterns such as GROUP BY, CASE, WHEN, UNION, SELECT in URL parameters
• Unusual database query errors or timeouts in application logs
• Abnormal database query patterns indicating data exfiltration attempts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the id parameter across the affected PHP files
• Monitor application and database logs for suspicious query patterns, errors, or unexpected data access
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
• Review web server access logs for requests containing encoded or obfuscated SQL syntax

Monitoring Recommendations

• Enable detailed logging for all database queries and monitor for anomalies
• Set up alerts for HTTP requests containing common SQL injection characters and keywords (', ", ;, --, UNION, SELECT, GROUP BY)
• Monitor for unusual network traffic patterns to and from the database server
• Implement database activity monitoring to detect unauthorized data access attempts

How to Mitigate CVE-2019-25636

Immediate Actions Required

• Restrict network access to the vulnerable Zeeways Jobsite CMS application if possible
• Implement a Web Application Firewall (WAF) with SQL injection detection rules as an interim protection measure
• Consider taking the application offline until a proper fix can be implemented
• Audit database logs and access patterns to identify potential exploitation

Patch Information

No official patch information is available from the vendor. Administrators should check the Zeeways product page for any updates or contact the vendor directly regarding remediation options.

For additional vulnerability details, refer to the VulnCheck Security Advisory.

Workarounds

• Implement input validation on the id parameter to ensure only numeric values are accepted
• Use parameterized queries (prepared statements) if modifying the application code is possible
• Deploy a WAF or reverse proxy with SQL injection filtering capabilities in front of the application
• Restrict database user privileges to limit the impact of successful SQL injection attacks

# Example WAF rule configuration (ModSecurity)
SecRule ARGS:id "!@rx ^[0-9]+$" \
    "id:100001,\
    phase:2,\
    deny,\
    status:403,\
    msg:'SQL Injection attempt blocked - invalid id parameter',\
