Security readout for executives and security teams
Plain-English summary
CVE-2020-7260 is a local code execution issue in the McAfee Application and Change Control installer before 8.3. If an attacker can compromise the folder used to run the installer, the installer may load attacker-controlled code. This is mainly a risk during installation or maintenance workflows on systems using affected MACC releases.
Executive priority
Treat this as a high-priority hardening and upgrade item where MACC is deployed. The business risk is strongest on managed endpoints and deployment workflows, because a local attacker could turn an installer run into code execution with high integrity and availability impact.
Technical view
The issue is a DLL side-loading vulnerability in the MACC installer prior to 8.3. CVSS 3.1 is 7.3 high: local attack vector, low complexity, low privileges, no user interaction, unchanged scope, low confidentiality impact, and high integrity and availability impact. The CVE maps to CWE-264.
Likely exposure
Exposure is most likely on Windows systems where McAfee Application and Change Control 8.x or 8.2.x installers are present or executed from writable or compromised folders. The source bundle does not provide CPEs, install prevalence, or broader platform details.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires local access and control over the folder from which the vulnerable installer runs. The available evidence supports local arbitrary code execution, not remote unauthenticated exploitation.
Researcher notes
Evidence is limited to the CVE record and McAfee advisory reference. The vulnerability is local DLL side loading through a compromised execution folder. No exploit code, active exploitation claim, CPE list, or detailed patch text is included in the provided bundle.
Mitigation direction
- Upgrade MACC environments away from installer versions prior to 8.3 per vendor guidance.
- Review McAfee advisory SB10313 for the authoritative fixed-version and upgrade details.
- Run installers only from trusted, access-controlled directories.
- Remove outdated MACC installer packages from shared or user-writable locations.
- Limit local user write access to software deployment folders.
Validation and detection
- Inventory MACC versions and installer packages across endpoints and deployment shares.
- Identify any MACC 8.x or 8.2.x installers retained in writable folders.
- Confirm installer execution paths are trusted and access-controlled.
- Review endpoint telemetry for unexpected code execution during MACC installation events.
- Check whether remediation aligns with McAfee advisory SB10313.
