CVE-2017-20223

Status: AnalyzedCritical (9.3)—

Telesquare SKT LTE Router SDT-CS3B1 firmware version 1.2.0 contains an insecure direct object reference vulnerability that allows attackers to bypass authorization and access resources by manipulating user-supplied input parameters. Attackers can directly reference objects in the system to retrieve sensitive information and access functionalities without proper access controls.

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).

🎯 ATT&CK techniques
