CVE-2020-36852

Estado: AplazadaCrítica (9.1)—

The Custom Searchable Data Entry System plugin for WordPress is vulnerable to unauthenticated database wiping in versions up to, and including 1.7.1, due to a missing capability check and lack of sufficient validation on the ghazale_sds_delete_entries_table_row() function. This makes it possible for unauthenticated attackers to completely wipe database tables such as wp_users.

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.
