CVE-2022-31784

Status: ModifiedCritical (9.8)—

A vulnerability in the management interface of MiVoice Business through 9.3 PR1 and MiVoice Business Express through 8.0 SP3 PR3 could allow an unauthenticated attacker (that has network access to the management interface) to conduct a buffer overflow attack due to insufficient validation of URL parameters. A successful exploit could allow arbitrary code execution.

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).
