DescriptionCVE.org

The Geo Mashup plugin for WordPress is vulnerable to Time-Based SQL Injection via the 'sort' parameter in all versions up to, and including, 1.13.18. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The esc_sql() function is applied but is ineffective in the ORDER BY context because the value is not enclosed in quotes. Additionally, while a sanitize_sort_arg() allowlist-based sanitizer was added in version 1.13.18, it is only applied in the AJAX code path (sanitize_query_args()) and not in the render-map.php or template tag code paths. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a time-based blind approach.

AnalysisAI

Time-based SQL injection in WordPress Geo Mashup plugin ≤1.13.18 allows unauthenticated remote attackers to extract sensitive database information. The 'sort' parameter in multiple code paths (render-map.php, template tags) lacks proper sanitization despite esc_sql() application, which is ineffective in ORDER BY contexts without quote encapsulation. Version 1.13.18 added allowlist-based sanitization but only protected the AJAX endpoint, leaving other attack vectors exploitable. EPSS and KEV data not available; vulnerability disclosed by Wordfence with public source code references confirming the flaw.

Technical ContextAI

This vulnerability affects the Geo Mashup WordPress plugin (cpe:2.3:a:cyberhobo:geo_mashup), a geolocation mapping tool for WordPress. The root cause is CWE-89 (SQL Injection) stemming from improper neutralization of special elements in SQL commands. Specifically, the plugin uses PHP's esc_sql() function on user-supplied 'sort' parameter values before inserting them into ORDER BY clauses, but this defense is ineffective because ORDER BY values are not quote-enclosed in SQL syntax. The sanitize_sort_arg() allowlist validator introduced in version 1.13.18 only protects the sanitize_query_args() AJAX code path, while render-map.php (line 166) and template tag functions remain vulnerable. The geo-mashup-db.php file (lines 1767, 1785) contains the vulnerable query construction logic. Time-based blind SQL injection techniques allow attackers to infer database contents character-by-character by measuring response delays, bypassing the lack of direct error messages or data output.

RemediationAI

Update to Geo Mashup version 1.13.19 or later, which applies changeset 3503627 containing comprehensive fixes across all code paths (https://plugins.trac.wordpress.org/changeset/3503627/). The patch extends sanitize_sort_arg() allowlist validation to render-map.php and template tag functions, not just AJAX handlers. If immediate patching is impossible, implement compensating controls with these specific trade-offs: (1) Disable the Geo Mashup plugin entirely until patching (eliminates attack surface but removes all mapping functionality), (2) Deploy WordPress Web Application Firewall (WAF) rules blocking requests with 'sort' parameter containing SQL keywords like SLEEP, BENCHMARK, WAITFOR (reduces but doesn't eliminate risk due to obfuscation techniques; may cause false positives if legitimate sort values match keywords), (3) Restrict wp-admin access to trusted IP addresses and implement database activity monitoring for slow queries exceeding 5-10 seconds (detection-focused control, doesn't prevent exploitation but enables incident response). Note that version 1.13.18 provides FALSE protection-administrators must verify they're running 1.13.19+ via WordPress admin dashboard or wp-content/plugins/geo-mashup/geo-mashup.php version header.
