CVE-2022-32256

Status: ModifiedMedium (6.5)—

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.1). The affected application consists of a web service that lacks proper access control for some of the endpoints. This could lead to low privileged users accessing privileged information.

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).
