CVE-2025-39484: Waituk Entrada SQL Injection Vulnerability

CVE-2025-39484 Overview

CVE-2025-39484 is a critical SQL Injection vulnerability affecting the Waituk Entrada WordPress theme. The vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89), allowing attackers to inject malicious SQL queries into the application. This issue affects all versions of the Entrada theme through version 5.7.7.

Critical Impact

This SQL Injection vulnerability enables unauthenticated attackers to extract sensitive information from the WordPress database, potentially compromising user credentials, personal data, and site configurations.

Affected Products

• Waituk Entrada WordPress Theme versions through 5.7.7

Technical Details for CVE-2025-39484

Vulnerability Analysis

This SQL Injection vulnerability exists in the Waituk Entrada WordPress theme due to insufficient input validation and sanitization. The flaw allows attackers to manipulate database queries by injecting malicious SQL statements through user-controllable input parameters. Since the vulnerability is accessible over the network without requiring authentication, it presents a significant risk to WordPress installations using this theme.

The vulnerability has been assigned a changed scope designation, meaning successful exploitation can affect resources beyond the vulnerable component itself. The primary impact is on data confidentiality, with potential for information disclosure of sensitive database contents. Additionally, there is a limited impact on system availability.

Root Cause

The root cause of CVE-2025-39484 is the failure to properly sanitize and validate user input before incorporating it into SQL queries. The Entrada theme does not adequately employ parameterized queries or prepared statements, allowing attacker-controlled input to be interpreted as part of the SQL command structure rather than as data values.

Attack Vector

The attack can be executed remotely over the network by unauthenticated users. An attacker can craft malicious HTTP requests containing SQL injection payloads that, when processed by the vulnerable theme, execute arbitrary SQL commands against the WordPress database.

The exploitation typically involves:

1. Identifying vulnerable input parameters within the Entrada theme
2. Crafting SQL injection payloads to extract database information
3. Leveraging techniques such as UNION-based injection, blind SQL injection, or time-based injection to enumerate database contents
4. Extracting sensitive data including user credentials, configuration settings, and stored content

Detection Methods for CVE-2025-39484

Indicators of Compromise

• Unusual database query patterns in server logs containing SQL syntax characters such as ', ", ;, --, or UNION
• Unexpected database errors or timeouts indicating attempted SQL injection
• Web server logs showing suspicious requests with encoded SQL payloads targeting theme endpoints
• Abnormal database read activity or data exfiltration patterns

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests
• Monitor WordPress database query logs for anomalous or malformed SQL statements
• Implement intrusion detection signatures for common SQL injection attack patterns
• Review access logs for requests containing SQL metacharacters targeting Entrada theme files

Monitoring Recommendations

• Enable comprehensive logging for WordPress and the underlying database server
• Configure alerting for database errors that may indicate injection attempts
• Monitor for unusual data access patterns that could suggest successful exploitation
• Implement real-time security monitoring for web application traffic

How to Mitigate CVE-2025-39484

Immediate Actions Required

• Update the Waituk Entrada theme to a patched version if available from the vendor
• If no patch is available, consider temporarily disabling or replacing the Entrada theme
• Implement WAF rules to filter SQL injection attempts at the network perimeter
• Conduct a database audit to identify any potential compromise from prior exploitation
• Review and strengthen database user permissions to minimize potential impact

Patch Information

Users should check with the Waituk vendor for an updated version of the Entrada theme that addresses this SQL Injection vulnerability. The Patchstack advisory may contain additional remediation guidance and patch availability information.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection detection rules to filter malicious requests
• Restrict access to the WordPress admin panel and theme-specific endpoints via IP whitelisting
• Use WordPress security plugins that provide runtime SQL injection protection
• If possible, temporarily switch to an alternative theme until a patch is released
