Security readout for executives and security teams
Plain-English summary
CVE-2021-0077 is a local privilege-escalation issue in the Intel VTune Profiler installer before version 2021.1.1. A user who already has authenticated local access may be able to gain higher privileges because of insecure inherited permissions.
Executive priority
Treat this as a targeted endpoint hardening issue, not an internet-facing emergency. Prioritize affected developer or shared systems because local privilege escalation can turn limited access into broader control.
Technical view
The CVE describes insecure inherited permissions in the Intel VTune Profiler installer before 2021.1.1. The attack path is local and authenticated. The provided sources do not include CVSS, CWE, detailed affected platforms, exploit details, or evidence of active exploitation.
Likely exposure
Exposure is most likely on developer, performance engineering, or lab systems where Intel VTune Profiler before 2021.1.1 is installed or installer artifacts remain accessible.
Exploitation context
No provided source reports active exploitation, and the CVE is not listed as KEV. Risk depends on whether an attacker already has local authenticated access to an affected system.
Researcher notes
The public bundle is sparse: no CVSS vector, CWE, platform matrix, or exploit status is provided. Analysis should stay anchored to local authenticated escalation through installer permission inheritance and Intel’s version boundary.
Mitigation direction
- Upgrade Intel VTune Profiler to version 2021.1.1 or later.
- Review Intel advisory INTEL-SA-00518 for official remediation details.
- Restrict local access on systems where vulnerable versions remain.
- Remove unused VTune installations or installer remnants.
- Monitor affected systems for unexpected privilege or permission changes.
Validation and detection
- Inventory systems for Intel VTune Profiler installations.
- Confirm installed VTune versions are 2021.1.1 or later.
- Review installer directories for inherited permissions exposure.
- Prioritize shared developer systems and performance testing hosts.
- Document any exception where upgrade is not immediately possible.
