CVE-2026-29103

Estado: AnalizadaAlta (7.2)—

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. A Critical Remote Code Execution (RCE) vulnerability exists in SuiteCRM 7.15.0 and 8.9.2, allowing authenticated administrators to execute arbitrary system commands. This vulnerability is a direct Patch Bypass of CVE-2024-49774. Although the vendor attempted to fix the issue in version 7.14.5, the underlying flaw in ModuleScanner.php regarding PHP token parsing remains.

Leer descripción completaMostrar menos

The scanner incorrectly resets its internal state ($checkFunction flag) when encountering any single-character token (such as =, ., or ;). This allows attackers to hide dangerous function calls (e.g., system(), exec()) using variable assignments or string concatenation, completely evading the MLP security controls. Versions 7.15.1 and 8.9.3 patch the issue.

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.

RCE en servicio remoto autenticado (PR:H) por fallo de parseo en ModuleScanner.php. Administrador ejecuta comandos arbitrarios, escalando desde acceso administrativo a control total del sistema.

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.
