AlienVault OTX Malware

open5gs

A vulnerability has been found in Open5GS up to 2.7.6. Affected by this vulnerability is an unknown functionality of the component GTPv2 Bearer Response Handler. Such manipulation leads to denial of service. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The name of the patch is 98f76e98df35cd6a35e868aa62715db7f8141ac1. A patch should be applied to remediate this issue.

CVE-2025-15528 is a denial of service vulnerability found in Open5GS, an open-source implementation of the 5G core network. The vulnerability affects versions 2.7.0 through 2.7.6 and resides in the GTPv2 Bearer Response Handler component. GTPv2 (GPRS Tunneling Protocol version 2) is critical for signaling and bearer management in 4G and 5G networks. The flaw allows an attacker to remotely send specially crafted messages to the vulnerable component, causing it to malfunction and crash or become unresponsive, resulting in denial of service. The attack requires no authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction required, and low impact on availability. The vulnerability has been publicly disclosed, and a patch is available identified by the commit hash 98f76e98df35cd6a35e868aa62715db7f8141ac1. While no active exploitation in the wild has been reported, the public availability of the exploit code increases the likelihood of future attacks. Open5GS is widely used by telecom operators and research institutions for 5G core network deployments, making this vulnerability a significant concern for critical telecommunications infrastructure.
