CVE-2022-45173
CWE-287Published: April 14, 2023· Updated: Jun 17, 2026
Official Description
An issue was discovered in LIVEBOX Collaboration vDesk through v018. A Bypass of Two-Factor Authentication can occur under the /api/v1/vdeskintegration/challenge endpoint. Because only the client-side verifies whether a check was successful, an attacker can modify the response, and fool the application into concluding that the TOTP was correct.
Risk Analysis
This vulnerability in LIVEBOX Collaboration vDesk allows an attacker to bypass two-factor authentication by manipulating client-side responses. Because the application relies on the client to verify success, an attacker can trick the system into accepting an incorrect TOTP, resulting in a critical 9.8 CVSS rating.
No public exploit is known, and the vulnerability is not in the KEV catalog. It is remotely exploitable.
Update vDesk to a version later than v018 to enforce server-side authentication verification.
Technical Analysis
CVE-2022-45173 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
