CVE-2018-9445

Status: ModifiedMedium (6.8)—Exploit
Severity6.8Medium · CVSS 3.0
Exploitation probability0.82 %higher than 57% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitAvailablePublished on Exploit-DB

In readMetadata of Utils.cpp, there is a possible path traversal bug due to a confused deputy. This could lead to local escalation of privilege when mounting a USB device with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android-6.0 Android-6.0.1 Android-7.0 Android-7.1.1 Android-7.1.2 Android-8.0 Android-8.1 Android ID: A-80436257.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
