CVE-2022-44311

Estado: ModificadaAlta (8.1)—💥 PoC

html2xhtml v1.3 was discovered to contain an Out-Of-Bounds read in the function static void elm_close(tree_node_t *nodo) at procesador.c. This vulnerability allows attackers to access sensitive files or cause a Denial of Service (DoS) via a crafted html file.

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.
