1) Authentication Bypass by Capture-replay (CVE-ID: N/A)

CWE-ID: CWE-294 - Authentication Bypass by Capture-replay

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to impersonate other users.

The vulnerability exists due to authentication bypass by capture-replay in the login authentication mechanism when processing a stolen login token without protocol encryption. A remote attacker can replay captured login data to impersonate other users.

User interaction is required to capture a victim's login, such as by tricking the victim into joining an attacker-controlled server. Captured tokens expire after a limited time, typically within 2-3 days.
