HPE Private 5G Core: Network processing flaw causes service disruption
Summary
HPE Private 5G Core, a software component for private cellular networks, is affected by a network processing vulnerability. A remote, unauthenticated attacker who can reach the network-facing component may cause a temporary service disruption, as only availability is affected. The CVE record does not describe the conditions that trigger the disruption, and the HPE advisory could not be read for this assessment.
Affected
- Private 5G Core: 0.0.0.0 to 1.26.1.4 (CVE record, CNA HPE)
- The lower bound 0.0.0.0 is a placeholder, not a verified start version.
- Not verified against HPE advisory HPESBNW05179, which may list different products or versions.
Fixed in
Unknown. No fixed version was found for this CVE. Do not assume that a fix exists.
Workaround
- No CVE-specific workaround found.
- Practical measure: restrict access to the network-facing Private 5G Core interfaces to trusted hosts only, and review firewall rules and management access.
- Confirm the measure against HPESBNW05179 before relying on it.
Exploitation
- Not known to be exploited. Secondary trackers do not list it in CISA KEV.
- No public exploit code has been confirmed at this time.
- NVD analysis pending.
Our recommendation
- Ask clients whether they run Private 5G Core and which version.
- Read HPE advisory HPESBNW05179 and confirm the affected and fixed versions.
- If affected and unpatched, restrict network access to the Private 5G Core interfaces to trusted hosts.
- Re-check KEV, NVD and the HPE advisory in a few days, as the record is new.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
