No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (Hewlett Packard Enterprise (HPE)) lists Hewlett Packard Enterprise (HPE) ClearPass Policy Manager (CPPM) versions 6.14.0 up to and including 6.14.0 and 6.11.0 up to and including 6.11.15 as affected. No release containing a fix is confirmed on record.

A vulnerability in a client interface of HPE Networking ClearPass Policy Manager could allow an unauthenticated remote attacker to conduct a DOM-based cross-site scripting (XSS) attack against a user of the affected client interface. Successful exploitation could allow an attacker to execute arbitrary script code in a victim's browser context within the affected client interface.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
