CVE-2024-14044: Buffer Overflow in Open5GS
CVE-2024-14044 is a medium severity buffer overflow vulnerability in Open5GS versions 2.7.0 and 2.7.1. It affects the Diameter Rx Handler component, specifically the function pcrf_rx_aar_cb in the file src/pcrf/pcrf-rx-path.c. The vulnerability arises from improper handling of the arguments num_of_media_component and num_of_sub, which can lead to a buffer overflow. The flaw can be exploited remotely without user interaction and requires low privileges. A public exploit exists. Upgrading to Open5GS version 2.7.2 addresses this issue.
AI Analysis
Technical Summary
This vulnerability in Open5GS up to version 2.7.1 involves a buffer overflow in the Diameter Rx Handler's pcrf_rx_aar_cb function due to manipulation of the num_of_media_component and num_of_sub arguments. The overflow can be triggered remotely, potentially allowing an attacker to cause memory corruption. The issue is fixed in version 2.7.2, with the patch identified by commit 87b4e4535c77ded627cdb6f4e4e2e3ea761f40b7. The CVSS 4.0 base score is 5.3, reflecting medium severity with network attack vector, low attack complexity, no user interaction, and limited confidentiality, integrity, and availability impacts.
Potential Impact
The buffer overflow vulnerability can be exploited remotely by an attacker with low privileges and no user interaction, potentially leading to memory corruption. The CVSS score indicates limited impact on confidentiality, integrity, and availability. There are no known exploits in the wild at this time, but a public exploit is available, which could increase risk if leveraged.
Mitigation Recommendations
Upgrade Open5GS to version 2.7.2 or later, which contains the official fix for this vulnerability. No other mitigations are specified or required as the patch fully addresses the issue.
