AlienVault OTX Vulnerabilities

AlienVault OTX Malware

Open5GS v2.7.5, prior to commit 67ba7f92bbd7a378954895d96d9d7b05d5b64615, is vulnerable to a NULL pointer dereference when a multipart/related HTTP POST request with an empty HTTP body is sent to the SBI of either AMF, AUSF, BSF, NRF, NSSF, PCF, SMF, UDM, or UDR, resulting in a denial of service. This occurs in the parse_multipart function in lib/sbi/message.c.

CVE-2025-55904 is a medium severity vulnerability affecting Open5GS version 2.7.5 and earlier, prior to a specific commit (67ba7f92bbd7a378954895d96d9d7b05d5b64615). Open5GS is an open-source implementation of the 5G core network, widely used for research, development, and some production environments. The vulnerability arises from a NULL pointer dereference in the parse_multipart function located in lib/sbi/message.c. Specifically, when a multipart/related HTTP POST request with an empty HTTP body is sent to the Service-Based Interface (SBI) of any of the core network functions—namely AMF (Access and Mobility Management Function), AUSF (Authentication Server Function), BSF (Binding Support Function), NRF (Network Repository Function), NSSF (Network Slice Selection Function), PCF (Policy Control Function), SMF (Session Management Function), UDM (Unified Data Management), or UDR (Unified Data Repository)—the system attempts to dereference a NULL pointer. This results in a denial of service (DoS) condition, causing the affected network function to crash or become unresponsive. The vulnerability is classified under CWE-476 (NULL Pointer Dereference), which typically leads to application crashes or system instability. The CVSS v3.1 base score is 4.0 (medium), reflecting that the attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts only availability (A:L) without affecting confidentiality or integrity. No known exploits are reported in the wild, and no official patches are linked yet. However, the vulnerability poses a risk to the stability and availability of 5G core network functions if exploited, potentially disrupting mobile network services dependent on Open5GS deployments.
