Name of the Vulnerable Software and Affected Versions
OpenSC (affected versions not specified)
Description
A flaw was found in OpenSC packages that allows a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Use of a Broken Cryptographic Algorithm
