CVE-2024-55988: Navayan CSV Export SQLi Vulnerability

CVE-2024-55988 Overview

CVE-2024-55988 is a Blind SQL Injection vulnerability affecting the Navayan CSV Export WordPress plugin developed by Amol Nirmala Waman. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to execute arbitrary SQL queries against the underlying database without proper authorization.

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). Blind SQL Injection is particularly dangerous as it allows attackers to extract sensitive data from databases even when error messages are suppressed, using time-based or boolean-based inference techniques.

Critical Impact

Attackers can exploit this vulnerability to extract sensitive data from the WordPress database, potentially compromising user credentials, administrative access, and other confidential information stored within the affected WordPress installation.

Affected Products

• Navayan CSV Export plugin versions through 1.0.9
• WordPress installations using the vulnerable navayan-csv-export plugin
• All WordPress sites with this plugin installed and active

Technical Details for CVE-2024-55988

Vulnerability Analysis

This Blind SQL Injection vulnerability exists within the Navayan CSV Export WordPress plugin, which is used for exporting data to CSV format. The plugin fails to properly sanitize user-controlled input before incorporating it into SQL queries. Because the injection is "blind," the application does not return database errors or query results directly to the attacker; instead, attackers must infer information through timing delays or conditional responses.

With an EPSS score of 7.793% (91.95th percentile), this vulnerability ranks significantly higher than most vulnerabilities in terms of exploitation probability, indicating elevated real-world risk.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) within the plugin's database operations. User-supplied data is concatenated directly into SQL queries without adequate sanitization, escaping, or the use of WordPress's built-in database abstraction layer ($wpdb->prepare()).

Attack Vector

Attackers can exploit this vulnerability by submitting maliciously crafted input through the plugin's user-facing functionality. Since this is a Blind SQL Injection, exploitation typically involves:

1. Boolean-based blind injection: Sending payloads that cause the application to behave differently based on whether a condition is true or false
2. Time-based blind injection: Using SQL commands like SLEEP() or BENCHMARK() to introduce measurable delays in server responses

The vulnerability allows attackers to extract database contents character by character, enumerate database structure, and potentially escalate to full database compromise. Successful exploitation could allow extraction of WordPress user credentials, access tokens, and other sensitive data.

Detection Methods for CVE-2024-55988

Indicators of Compromise

• Unusual database query patterns in MySQL/MariaDB slow query logs containing SQL injection payloads
• HTTP requests to WordPress containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP(), or BENCHMARK()
• Abnormally slow response times on endpoints associated with the Navayan CSV Export plugin
• Evidence of data exfiltration or unauthorized database access in server logs

Detection Strategies

• Monitor web application firewall (WAF) logs for SQL injection patterns targeting WordPress plugin endpoints
• Implement database activity monitoring to detect unusual query patterns or excessive query execution times
• Review Apache/Nginx access logs for requests containing encoded SQL injection payloads to plugin-related URLs
• Deploy SentinelOne Singularity to detect and block exploitation attempts through behavioral analysis

Monitoring Recommendations

• Enable detailed query logging on WordPress database servers to capture potential injection attempts
• Configure alerting for requests containing common SQL injection keywords and functions
• Implement rate limiting on plugin endpoints to mitigate automated exploitation tools
• Regularly audit WordPress plugin inventory to identify and track vulnerable installations

How to Mitigate CVE-2024-55988

Immediate Actions Required

• Deactivate and remove the Navayan CSV Export plugin (navayan-csv-export) immediately if running version 1.0.9 or earlier
• Review WordPress database for signs of unauthorized access or data manipulation
• Reset database credentials and WordPress user passwords if compromise is suspected
• Implement a Web Application Firewall (WAF) rule to block SQL injection attempts

Patch Information

At the time of publication, no patched version has been confirmed. Users are advised to check the Patchstack SQL Injection Advisory for the latest remediation guidance and monitor the WordPress plugin repository for security updates.

Workarounds

• Disable or uninstall the Navayan CSV Export plugin until a security patch is released
• Implement WAF rules to filter SQL injection payloads targeting WordPress installations
• Restrict access to the WordPress admin panel and plugin functionality to trusted IP addresses only
• Use WordPress security plugins to add an additional layer of input validation and SQL injection protection

# WordPress plugin deactivation via WP-CLI
wp plugin deactivate navayan-csv-export --path=/var/www/html/wordpress

# Remove the vulnerable plugin entirely
wp plugin delete navayan-csv-export --path=/var/www/html/wordpress

# Verify plugin removal
wp plugin list --path=/var/www/html/wordpress | grep navayan
