OpenSC before 0.11.5 uses weak permissions (ADMIN file control information of 00) for the 5015 directory on smart cards and USB crypto tokens running Siemens CardOS M4, which allows physically proximate attackers to change the PIN.
Weaknesses in this category are related to the design and implementation of data confidentiality and integrity. Frequently these deal with the use of encoding techniques, encryption libraries, and hashing algorithms. The weaknesses in this category could lead to a degradation of the quality data if they are not addressed.
