A type confusion vulnerability has been identified in Free5GC version 4.2.0, specifically within an unknown function of the APER component. This vulnerability allows for remote exploitation, although it is characterized by high complexity and difficulty. The issue arises because Free5GC accepts non-printable strings in fields that are defined as requiring printable strings, such as the RANNodeName in the NGSetupRequest. This discrepancy could lead to crashes or bugs when the improperly formatted data is processed later.
Users are advised to update to the patched version of Free5GC, which is available on the Free5GC GitHub repository.
