SQL Injection in XMB u2u_send_recp Function

IdentifiersCVE-2006-3994CWE-89

CVE-2006-3994 is an SQL injection vulnerability in the u2u_send_recp function within u2u.inc.php of XMB (Extreme Message Board) version 1.9.6 Alpha and earlier. The vulnerability arises because the u2uid parameter, received via POST to u2u.php, is used directly in SQL queries without proper sanitization, bypassing the application's protection scheme.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An attacker can exploit this vulnerability to execute arbitrary SQL commands on the backend database. This can lead to unauthorized data access, data modification, or potentially full compromise of the application and its data.

Mitigation

If you can’t patch tonight, do this now.

As an immediate mitigation, restrict access to u2u.php, implement web application firewall (WAF) rules to block malicious SQL injection attempts, and validate and sanitize all user input at the application level.

Remediation

Patch, then assume compromise.

Upgrade to a version of XMB where this vulnerability is patched. Ensure that all user-supplied input is properly sanitized and parameterized before being used in SQL queries, especially in the u2u_send_recp function.
