Description
Pingvin Share X is a secure and easy self-hosted file sharing platform. From 1.14.1 to 1.16.2, a critical authentication bypass vulnerability allows an attacker who has obtained a valid username and password to skip the second-factor authentication (TOTP) requirement entirely. Although, an attacker still needs the user's password to reach this stage. This vulnerability is fixed in 1.16.3.

AI Analysis

Impact

A critical authentication bypass flaw allows an attacker who knows a valid username and password to skip the required TOTP second‑factor authentication. The vulnerability requires the attacker to already possess valid user credentials, which can be obtained through credential compromise or social engineering. Once bypassed, the attacker can access the file sharing platform with full privileges, compromising confidential data and integrity of stored files.

Affected Systems

Pingvin Share X self‑hosted file sharing platform, versions 1.14.1 through 1.16.2, provided by smp46.

Risk and Exploitability

The CVSS score of 9.1 indicates a high‑severity flaw. Although no EPSS score is available, the absence of a KEV listing does not diminish the seriousness of the issue. Exploitation requires valid credentials, making the attack vector credential‑dependent but feasible for attackers who have already stolen or guessed passwords. Given the severity and the potential for unfettered access, the risk remains substantial.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Pingvin Share X to version 1.16.3 or later to apply the vendor‑issued fix.
  • Verify that the configuration enforces two‑factor authentication for all accounts and disable any setting that permits password‑only logins.
  • Audit login logs for unexpected or repeated successful logins that bypass TOTP and, if needed, reset credentials for affected accounts.
