CVE-2023-23119

Status: ModifiedMedium (5.9)—

The use of the cyclic redundancy check (CRC) algorithm for integrity check during firmware update makes Ubiquiti airFiber AF2X Radio firmware version 3.2.2 and earlier vulnerable to firmware modification attacks. An attacker can conduct a man-in-the-middle (MITM) attack to modify the new firmware image and bypass the checksum verification.

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).
