CVE-2018-1243

Estado: ModificadaAlta (7.5)—

Dell EMC iDRAC6, versions prior to 2.91, iDRAC7/iDRAC8, versions prior to 2.60.60.60 and iDRAC9, versions prior to 3.21.21.21, contain a weak CGI session ID vulnerability. The sessions invoked via CGI binaries use 96-bit numeric-only session ID values, which makes it easier for remote attackers to perform bruteforce session guessing attacks.

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).
