The Vivo V7 device with a build fingerprint of vivo/1718/1718:7.1.2/N2G47H/compil11021857:user/release-keys allows any app co-located on the device to set system properties as the com.android.phone user. The com.qualcomm.qti.modemtestmode app (versionCode=25, versionName=7.1.2) that contains an exported service named com.qualcomm.qti.modemtestmode.MbnTestService that allows any app co-located on the device to provide key-value pairs to set certain system properties. Notably, system properties with the persist.* prefix can be set which will survive a reboot. On the Vivo V7 device, when the persist.sys.input.log property is set to have a value of yes, the user's screen touches be written to the logcat log by the InputDispatcher for all apps. The system-wide logcat log can be obtained from external storage via a different known vulnerability on the device. The READ_EXTERNAL_STORAGE permission is necessary to access the log files containing the user's touch coordinates. With some effort, the user's touch coordinates can be mapped to key presses on a keyboard.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
