CVE-2023-28368

Status: ModifiedMedium (5.7)—

TP-Link L2 switch T2600G-28SQ firmware versions prior to 'T2600G-28SQ(UN)_V1_1.0.6 Build 20230227' uses vulnerable SSH host keys. A fake device may be prepared to spoof the affected device with the vulnerable host key.If the administrator may be tricked to login to the fake device, the credential information for the affected device may be obtained.

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).
