CVE-1999-1389

Status: ModifiedHigh (7.5)—

US Robotics/3Com Total Control Chassis with Frame Relay between 3.6.22 and 3.7.24 does not properly enforce access filters when the "set host prompt" setting is made for a port, which allows attackers to bypass restrictions by providing the hostname twice at the "host: " prompt.

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).
