HPE Private 5G Core: Authentication and session management flaw allows continued access
Summary
Hewlett Packard Enterprise Private 5G Core (P5G Core) contains a flaw in its authentication and session management. In certain account or session state changes, access may not be fully terminated. A remote user with prior legitimate access could keep access to protected resources beyond the intended period. The advisory does not describe the trigger conditions.
Affected
- Hewlett Packard Enterprise Private 5G Core (P5G Core) versions 0.0.0.0 to 1.26.1.4 (per CVE record; 0.0.0.0 is a placeholder for all versions)
Fixed in
- Unknown. The vendor advisory could not be verified. Do not assume that 1.26.1.3 or later fixes this issue.
Workaround
- Unknown. No vendor workaround could be verified.
- Interim measure: enforce timely revocation of accounts and sessions and restrict management and user interfaces to trusted networks.
Exploitation
- No public proof of concept known (secondary source).
- Not known to be exploited; not listed in CISA KEV (secondary sources, not directly verified).
Our recommendation
- Check whether P5G Core is deployed in your environment. If not, no action is needed.
- Ask HPE support or check security bulletin hpesbnw05179en_us for the fixed release and workaround, then patch promptly.
- Until a fix is applied, review and enforce account and session revocation (offboarding, role changes, session expiry) and restrict access to trusted networks.
- Review access logs for sessions that remain active after an account was disabled.
- Treat this as high priority if P5G Core is in use; priority is low for SMEs without it.
