Authentication Bypass in the PAPI Protocol of AOS-8 Allows Unauthorized Administrative Access

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 vulnerability has been identified in the PAPI protocol of AOS-8 that could potentially allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data.
