Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the buffer overflow by requiring timely remediation through patching to Magma v1.9 or the fixing commit.
Requires validation of incoming NAS packets to prevent crafted inputs from triggering the buffer overflow in the decode_traffic_flow_template_packet_filter function.
Implements memory protection mechanisms such as address space layout randomization and stack canaries to mitigate exploitation of the buffer overflow vulnerability.
NVD Description
The Linux Foundation Magma <= 1.8.0 (fixed in v1.9 commit 08472ba98b8321f802e95f5622fa90fec2dea486) was discovered to contain a buffer overflow in the decode_traffic_flow_template_packet_filter function at /3gpp/3gpp_24.008_sm_ies.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted NAS packet.
Deeper analysisAI
CVE-2024-24419 is a buffer overflow vulnerability (CWE-120) in the Linux Foundation's Magma project, affecting versions up to and including 1.8.0. The flaw resides in the decode_traffic_flow_template_packet_filter function within the file /3gpp/3gpp_24.008_sm_ies.c. It enables attackers to trigger a Denial of Service (DoS) through a crafted NAS (Non-Access Stratum) packet and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). The issue was addressed in Magma v1.9 via commit 08472ba98b8321f802e95f5622fa90fec2dea486.
The vulnerability is exploitable remotely over the network with low attack complexity, requiring no authentication, privileges, or user interaction. An unauthenticated attacker can send a specially crafted NAS packet to the affected Magma instance, causing the buffer overflow and resulting in a DoS that severely impacts service availability without affecting confidentiality or integrity.
According to available advisories, mitigation requires updating to Magma v1.9 or applying the specified fixing commit. Further details on the vulnerability and remediation are provided at https://cellularsecurity.org/ransacked.
