CVE-2026-73719

Status: ModifiedHigh (7.2)—

An arbitrary file write vulnerability exists in the API of HPE Networking Fabric Composer and could allow an authenticated administrative user to escalate privileges. Successful exploitation of this vulnerability may enable the attacker to execute arbitrary system commands with root privileges on the underlying operating system.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

AV:N y PR:H en API indica explotación remota con privilegios administrativos (T1210). La vulnerabilidad de escritura arbitraria permite escalar a root y ejecutar comandos del sistema (T1068+T1059).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
