HP Support Assistant 9.55.10.0 Fixes Local Privilege Escalation
Tech GuruQuick Answer
The authority published HPSBGN04141 for HP Support Assistant releases before 9.55.10.0. HP disclosed a local privilege-escalation vulnerability that can affect confidentiality, integrity, and availability when an attacker already has low privileges and the required local conditions are present. Affected deployments should be matched to the authority's exact scope and moved to the supported fixed release.
Confirm Scope And Apply The Supported Fix
What to do now: Inventory HP Support Assistant releases before 9.55.10.0, match the exact affected release or feature, apply the authority-supported fixed build or service remediation, validate the dependent workflow, and preserve evidence.

What Changed
HP disclosed a local privilege-escalation vulnerability that can affect confidentiality, integrity, and availability when an attacker already has low privileges and the required local conditions are present.
What To Validate Now
- Inventory. Locate HP Support Assistant releases before 9.55.10.0 deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: HP Support Assistant versions earlier than 9.55.10.0. Do not infer applicability from product family or severity alone.
- Remediate. Apply HP Support Assistant 9.55.10.0 or later through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Use the exact supported release stream and repository. Test dependencies, clusters, integrations, and rollback before broad deployment; a CVSS rating or reachable feature is not evidence of exploitation.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
