CVE-2001-1291
Estado: ModificadaCrítica (9.8)—💥 Exploit
The telnet server for 3Com hardware such as PS40 SuperStack II does not delay or disconnect remote attackers who provide an incorrect username or password, which makes it easier to break into the server via brute force password guessing.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 8.90%
- Percentil entre todas las CVEs puntuadas: 95
- Fecha de la puntuación: 8/10/2026
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.
