CVE-2023-37008 Details
Description
Open5GS MME versions <= 2.6.4 contain a buffer overflow in the ASN.1 deserialization function of the S1AP handler. This buffer overflow causes type confusion in decoded fields, leading to invalid parsing and freeing of memory. An attacker may use this to crash an MME or potentially execute code in certain circumstances.
A buffer overflow vulnerability has been identified in the Open5GS MME component, specifically in versions through 2.6.4. The issue arises within the S1AP handler's ASN.1 deserialization function, where improper handling of message lengths can lead to memory corruption. This vulnerability causes type confusion in the decoded fields, allowing for invalid parsing and manipulation of memory. An attacker could exploit this vulnerability to crash the MME or potentially execute arbitrary code under certain conditions.
Users can upgrade to Open5GS version 2.7.0 or later, where this vulnerability has been fixed.
