CVE-2026-85746
Noticias y reportajes en Orbitaley
MariaDB server es un fork de MySQL server desarrollado por la comunidad. Desde la 10.6.1 hasta la 10.6.28, la 10.11.19, la 11.4.13, la 11.8.9, la 12.3.3 y la 13.0.2, ST_AsText puede escribir más allá de un búfer de salida asignado al convertir GeometryCollections muy anidadas, porque la serialización WKT recursiva no tiene en cuenta los bytes consumidos ni reserva espacio suficiente. Un atacante remoto con pocos privilegios puede enviar un objeto GIS especialmente diseñado para corromper la memoria y, potencialmente, lograr la ejecución de código si se combina con otra vulnerabilidad. Este problema se ha corregido en las versiones 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3 y 13.0.2.

Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1210Exploitation of Remote Serviceslateral movement90 %
Vector AV:N/PR:L/UI:N indica red con privilegios bajos; la corrupción de memoria en ST_AsText permite posible ejecución de código, pero solo combinada con otra vulnerabilidad.
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.

From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, ST_AsText can write beyond an allocated output buffer when converting deeply nested GeometryCollections because recursive WKT serialization does not account for bytes consumed or reserve sufficient space. A low-privileged remote attacker can submit a specially crafted GIS object to corrupt memory and potentially achieve code execution when combined with another vulnerability. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2."
