Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a time-based blind SQL Injection in the Booking Calendar WordPress plugin (versions up to 10.14.8). It occurs because the 'dates_to_check' parameter is not properly sanitized or escaped before being used in SQL queries. This allows unauthenticated attackers to inject malicious SQL code by appending additional queries, potentially extracting sensitive information from the database. [2]
How can this vulnerability impact me? :
The vulnerability can allow attackers to extract sensitive information from the database without authentication by exploiting the SQL injection flaw. This can lead to data breaches, exposure of confidential booking data, and compromise of the website's integrity and user privacy. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
To detect this vulnerability, you can monitor HTTP requests to the Booking Calendar plugin endpoints for suspicious usage of the 'dates_to_check' parameter containing SQL injection payloads. For example, you can use network traffic inspection tools like Wireshark or tcpdump to capture traffic and grep for suspicious patterns. On the server, you can check web server logs for requests with unusual 'dates_to_check' parameter values that include SQL syntax (e.g., quotes, AND, OR, UNION). Example commands: 1) Using grep on access logs: grep "dates_to_check" /var/log/apache2/access.log | grep -E "('|--|;|AND|OR|UNION)" 2) Using tcpdump to capture HTTP traffic: tcpdump -A -s 0 'tcp port 80' | grep "dates_to_check" 3) Using curl to test injection: curl -G 'http://yourwordpresssite.com/wp-content/plugins/booking_calendar/' --data-urlencode "dates_to_check[]=2025-01-01' OR '1'='1" These methods help identify attempts to exploit the SQL injection vulnerability via the 'dates_to_check' parameter. [2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include: 1) Update the Booking Calendar plugin to version 10.14.9.1 or later, which includes the security fix that sanitizes and properly prepares SQL queries involving the 'dates_to_check' parameter to prevent SQL injection. 2) If updating immediately is not possible, consider temporarily disabling the Booking Calendar plugin to prevent exploitation. 3) Implement Web Application Firewall (WAF) rules to block requests containing suspicious SQL injection patterns in the 'dates_to_check' parameter. 4) Monitor logs for suspicious activity targeting this parameter. The security fix involves sanitizing input dates and using parameterized SQL queries with $wpdb->prepare() to prevent injection. [2]
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows unauthenticated attackers to perform time-based blind SQL Injection to extract sensitive information from the database. This exposure of sensitive data could lead to non-compliance with data protection regulations such as GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access. Therefore, the vulnerability poses a risk to compliance with these standards until it is properly mitigated. [2]
