CVE-2020-26068

Status: ModifiedMedium (6.5)—

A vulnerability in the xAPI service of Cisco Telepresence CE Software and Cisco RoomOS Software could allow an authenticated, remote attacker to generate an access token for an affected device. The vulnerability is due to insufficient access authorization. An attacker could exploit this vulnerability by using the xAPI service to generate a specific token. A successful exploit could allow the attacker to use the generated token to enable experimental features on the device that should not be available to users.

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).
