CVE-2018-1943

Estado: ModificadaMedia (5.4)—

IBM Cloud Private 3.1.0 and 3.1.1 is vulnerable to HTTP HOST header injection, caused by improper validation of input. By persuading a victim to visit a specially-crafted Web page, a remote attacker could exploit this vulnerability to inject arbitrary HTTP headers, which will allow the attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking. IBM X-Force ID: 153385.

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).
