CVE-2015-20121

Estado: AnalizadaAlta (8.8)—

Next Click Ventures RealtyScript 4.0.2 contains SQL injection vulnerabilities that allow unauthenticated attackers to manipulate database queries by injecting arbitrary SQL code through the GET parameter 'u_id' in /admin/users.php and the POST parameter 'agent[]' in /admin/mailer.php. Attackers can exploit time-based blind SQL injection techniques to extract sensitive database information or cause denial of service through sleep-based payloads.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

SQL injection en aplicación web expuesta (AV:N, PR:N, UI:N) accesible sin autenticación permite extraer datos sensibles de BD (T1005) o manipularlos (T1565.001), y DoS mediante payloads sleep-based (T1499.004). CWE-89 y RealtyScript 4.0.2 confirman inyección SQL.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
