HPE Private 5G Core: Access control vulnerability permits unauthorized access
Summary
A flaw in an unspecified system interface of HPE Private 5G Core (P5G Core) can allow an attacker to bypass authorization boundaries under certain conditions. A successful attack could allow unauthorized access to or modification of protected system information, with low impact on confidentiality and integrity. The CVSS base score is 6.5 (medium) and no privileges or user interaction are required, so the risk depends mainly on whether management or service interfaces are reachable from untrusted networks.
Affected
- HPE Private 5G Core (P5G Core), versions 1.26.1.4 and earlier (per CVE record; 0.0.0.0 is a placeholder lower bound)
Fixed in
- Unknown. The fixed release is not confirmed in the sources reviewed; check HPE bulletin HPESBNW05179 (Resolution section).
Workaround
- Unknown. No CVE-specific workaround was found.
- General hardening: restrict management interfaces to a dedicated layer 2 segment/VLAN and control access with firewall policies at layer 3 and above (not an HPE-stated mitigation for this CVE).
Exploitation
- No public technical details found; the vulnerable interface is not named.
- Secondary aggregator sites report no known exploitation and no public exploit code; the CISA KEV catalog should be re-checked.
- HPE's statement on exploitation could not be verified.
Our recommendation
- Identify whether P5G Core is deployed and which version is running.
- If version 1.26.1.4 or earlier is in use, plan an upgrade as soon as HPE publishes the fixed release in bulletin HPESBNW05179.
- Restrict P5G Core management and service interfaces to trusted networks and monitor them for unusual access.
- Re-check the CISA KEV catalog and the HPE bulletin regularly.
