Authenticated Buffer Overflow Vulnerability in the API Endpoint of HPE Networking Instant On Causes Denial-of-Service

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

A buffer overflow vulnerability exists in the API endpoint of HPE Networking Instant On that could allow an authenticated attacker with administrative privileges to cause a denial of service.
