CVE-2015-2868

Status: ModifiedCritical (9.8)—

An exploitable remote code execution vulnerability exists in the Trane ComfortLink II firmware version 2.0.2 in DSS service. An attacker who can connect to the DSS service on the Trane ComfortLink II device can send an overly long REG request that can overflow a fixed size stack buffer, resulting in 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).
