HPE Private 5G Core (AthonetOS): Unauthorized access and service integrity impact
Summary
A vulnerability in AthonetOS, the operating system of HPE Private 5G Core (formerly Athonet), may allow an unauthorized party to affect service operation or access protected system functions. According to the CVSS vector, the attack is possible over the network without privileges or user interaction and with low complexity. The vendor's description and the vector disagree on the impact type (integrity versus confidentiality), and the exact prerequisites are not yet documented.
Affected
- HPE Private 5G Core (P5G Core), all versions up to and including 1.26.1.4
- The lower bound 0.0.0.0 in the CVE record is a placeholder for all earlier versions.
Fixed in
- Unknown. The fixed version is not confirmed in the sources reviewed. See HPE bulletin HPESBNW05179en_us.
Workaround
- Unknown. No vendor workaround was found in the sources reviewed.
- Interim measure: restrict management and service interfaces to trusted networks and keep the core off the public internet.
Exploitation
- Not known to be exploited at the time of writing. CISA KEV status was not verified directly.
- No public proof of concept found.
- A public scanning template reportedly can find exposed instances.
Our recommendation
- Check whether any Private 5G Core or Athonet instance is in use.
- If in use, read HPE bulletin HPESBNW05179 for the fixed version and apply it, together with the sibling CVEs in the same bulletin.
- Confirm that core management and service interfaces are not reachable from the internet or untrusted networks.
- Recheck NVD and CISA KEV, as the CVE was published only recently and analysis is pending.
