Lifecycle Timeline
4DescriptionCVE.org
A vulnerability has been identified in the Acer Agent Service component included with NitroSense and PredatorSense. Insufficient access controls within a privileged service may allow an authenticated local user to perform unauthorized registry operations. In certain situations, this could lead to privilege escalation or compromise of the affected system.

AnalysisAI
Local privilege escalation in the Acer Agent Service bundled with Acer NitroSense and PredatorSense lets an authenticated local user on an affected Windows laptop perform unauthorized registry operations through insufficiently controlled access in the service, potentially obtaining higher privileges and compromising the machine. The issue is rated CVSS 7.4 (CVSS v4.0 AV:L/AC:L/AT:N/PR:L/UI:N with High impact across confidentiality, integrity and availability, including subsequent-system impact), and our assessment aligns with a CVSS v3.1 vector of AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, so the practical prerequisite is that the attacker already holds a low-privilege local account on a host where the OEM utility and its privileged service are installed and running. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an already-authenticated local user on a Windows system where Acer's NitroSense or PredatorSense software (and its bundled privileged Acer Agent Service) is installed - i.e., Acer Nitro/Predator gaming laptops with the OEM utility running. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine local privilege-escalation issue but not an urgent, mass-exploitable one. … 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 | Patch status is not confirmed in the available data: no exact fixed version, GitHub commit, or patch reference was supplied, so rather than assuming a fix does not exist, check the Acer advisory at https://community.acer.com/en/kb/articles/19872 and update NitroSense and PredatorSense through Acer Care Center or the vendor's support page to the latest available build, confirming with Acer support that the Acer Agent Service component has been replaced if no version is documented. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows endpoints running Acer NitroSense or PredatorSense (including consumer-grade laptops used by staff) to establish the affected population, and confirm that personnel operate with standard, non-administrative accounts so the prerequisite low-privilege foothold cannot be combined with broad local admin rights; also open a support case with Acer to obtain a remediation timeline, since no vendor patch is currently available. …
