CVE-ID: CVE-2022-39249

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

Exploit availability: No

Description

3) Insufficient verification of data authenticity

EUVDB-ID: #VU67745

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-39250

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass SAS verification.

The vulnerability exists due to checking and signing user identities and devices in two separate steps, and inadequately fixing the keys to be signed between these steps. A remote attacker cooperating with a malicious home server can interfere with the verification flow between two users, injecting its own cross-signing user identity in place of one of the users’ identities, leading to the other device trusting/verifying the user identity under the control of the home server instead of the intended one.

Mitigation
