SQL Injection in YesWiki Bazar Module Entry Management

YesWiki is a wiki system written in PHP. Prior to version 4.6.1, YesWiki bazar module contains a SQL injection vulnerability in tools/bazar/services/EntryManager.php at line 704. The $data['id_fiche'] value (sourced from $_POST['id_fiche']) is concatenated directly into a raw SQL query without any sanitization or parameterization. This issue has been patched in version 4.6.1.

Casky was already ahead

This CVE exploits attack patterns that Casky's 301matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

YesWiki, a PHP-based wiki system, contains a critical SQL injection vulnerability in its bazar module prior to version 4.6.1. The vulnerability exists in EntryManager.php where the id_fiche parameter from POST requests is directly concatenated into SQL queries without sanitization or parameterization. This allows unauthenticated or authenticated attackers to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion of database contents. Organizations running YesWiki versions before 4.6.1 that expose the bazar module to untrusted users face immediate risk of data compromise and should prioritize upgrading to the patched version.

Casky's 301 mapped security skills leverage Claude's extended reasoning to detect the attack patterns associated with this vulnerability across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance via reconnaissance patterns). Practitioners using Casky would identify detection signals including: SQL error messages in web application logs, anomalous database query patterns with injected SQL syntax, unexpected POST parameter values containing SQL keywords or escape sequences in bazar module endpoints, and database access attempts with elevated privileges from the application service account. The platform's skill mapping would flag suspicious patterns in EntryManager.php function calls, parameter handling inconsistencies, and raw query construction without prepared statements—enabling security teams to correlate these indicators with active exploitation attempts and implement targeted defensive measures.
