CVE-2023-29478

Estado: ModificadaCrítica (9.8)—💥 PoC

BiblioCraft before 2.4.6 does not sanitize path-traversal characters in filenames, allowing restricted write access to almost anywhere on the filesystem. This includes the Minecraft mods folder, which results in code execution.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
