A potential security vulnerability has been identified in the HP Support Assistant for versions prior to 9.55.10.0. The vulnerability could potentially allow a local attacker to escalate privileges due to insufficient access controls.
Articles & Coverage 1
AnalysisAI
Local privilege escalation in HP Support Assistant versions prior to 9.55.10.0 allows an authenticated local attacker to gain elevated privileges on affected Windows hosts through insufficient access controls (CWE-269, improper privilege management). The flaw is not remotely reachable and requires the attacker to already hold low-privileged local access plus satisfaction of a specific attack precondition (expressly flagged as AT:P in the CVSS 4.0 vector), which constrains reliable exploitation; no public exploit code and no confirmed active exploitation were identified at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Requires local access with low but existing privileges (PR:L) to an HP Windows PC running HP Support Assistant before version 9.55.10.0; no user interaction is needed (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a locally-exploitable privilege escalation (CWE-269, improper privilege management) in HP Support Assistant, a utility pre-installed on HP consumer and small-business Windows PCs. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade HP Support Assistant to version 9.55.10.0 or later, as documented in HP Security Bulletin HPSBGN04141 (https://support.hp.com/us-en/document/ish_15677182-15677204-16/hpsbgn04141); update via the built-in updater or by downloading the current installer from HP Support. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every Windows endpoint running HP Support Assistant and record its version, prioritizing the build to 9.55.10.0 or later; where the tool is not business-required, remove it outright, and where it is retained, confirm standard users hold no local administrative rights so the precondition for escalation is harder to satisfy. …
