Overview<\/strong><\/p>\n

This report covers the details of CVE-2025-6177, a high-severity privilege escalation vulnerability in MiniOS on Google ChromeOS. This vulnerability poses a significant threat to enrolled devices, potentially allowing a local attacker to gain root code execution. Addressing this issue is of paramount importance as it could lead to system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-6177
\nSeverity: High (CVSS 7.4)
\nAttack Vector: Local
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: System Compromise and Potential Data Leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Google ChromeOS | 16063.45.2 and potentially others<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the debug shell (VT3 console) of MiniOS in Google ChromeOS. This debug shell is accessible through specific key combinations during the entry to developer mode and MiniOS access. An attacker can exploit this vulnerability to gain root code execution, even when the developer mode is blocked by device policy or Firmware Write Protect (FWMP).<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

This is a conceptual example of how the vulnerability might be exploited. In this case, the attacker would need physical access to the device to trigger the debug shell and root code execution:<\/p>\n

# Attacker accesses the VT3 console\nCtrl+Alt+F2\n# Attacker enters root shell\nchronos\n# Attacker exploits the vulnerability to gain root access\nsudo \/bin\/bash<\/code><\/pre>\n
Mitigation Guidance<\/strong><\/p>\n
Users are advised to apply the vendor patch as soon as it becomes available. Until then, the use of Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can serve as temporary mitigation. It’s also advised to restrict physical access to devices and disable unnecessary debug features.<\/p>\n","protected":false},"excerpt":{"rendered":"
