AlienVault OTX Vulnerabilities

AlienVault OTX Malware

Assertion failure in function ngap_build_downlink_nas_transport in file src/amf/ngap-build.c, the Access and Mobility Management Function (AMF) component, in Open5GS thru 2.7.5 allowing attackers to cause a denial of service or other unspecified impacts via repeated UE connect and disconnect message sequences.

CVE-2025-52288 is a vulnerability identified in the Access and Mobility Management Function (AMF) component of Open5GS, an open-source implementation of the 5G core network. The flaw arises from an assertion failure within the function ngap_build_downlink_nas_transport located in the source file src/amf/ngap-build.c. This assertion failure can be triggered by an attacker through repeated sequences of User Equipment (UE) connect and disconnect messages. The assertion failure indicates that the software encounters an unexpected state or condition during the processing of these messages, which can cause the AMF component to crash or behave unpredictably. The primary impact of this vulnerability is a denial of service (DoS), where the AMF service becomes unavailable, potentially disrupting 5G network operations. While the description mentions 'other unspecified impacts,' no further technical details or exploit code are currently available, and no known exploits have been observed in the wild. The vulnerability affects Open5GS versions up to 2.7.5, though specific affected versions are not explicitly listed. Since Open5GS is widely used for 5G core network implementations, this vulnerability could impact operators and organizations deploying private or public 5G networks using this software. The lack of a CVSS score and absence of a patch link indicate that remediation guidance may still be pending or under development. Given the nature of the vulnerability, exploitation requires the ability to send crafted UE connect/disconnect message sequences to the AMF, which may require network access or control over UE signaling traffic.
