CVE-2021-22449

Status: ModifiedHigh (7.5)—

There is a logic vulnerability in Elf-G10HN 1.0.0.608. An unauthenticated attacker could perform specific operations to exploit this vulnerability. Due to insufficient security design, successful exploit could allow an attacker to add users to be friends without prompting in the target device.

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).
