VAR-202007-0755
Vulnerability from variot - Updated: 2023-12-18 13:12A PIN management problem was discovered on Yubico YubiKey 5 devices 5.2.0 to 5.2.6. OpenPGP has three passwords: Admin PIN, Reset Code, and User PIN. The Reset Code is used to reset the User PIN, but it is disabled by default. A flaw in the implementation of OpenPGP sets the Reset Code to a known value upon initialization. If the retry counter for the Reset Code is set to non-zero without changing the Reset Code, this known value can be used to reset the User PIN. To set the retry counters, the Admin PIN is required. Yubico YubiKey 5 An unspecified vulnerability exists in the device.Information may be tampered with. Yubico YubiKey 5 is a multi-protocol security key device from Yubico, Sweden.
The OpenPGP implementation in Yubico YubiKey 5 5.2.0 to 5.2.6 has an access control error vulnerability. The vulnerability stems from the network system or product improperly restricting access to resources from unauthorized roles
