CVE-2022-26579Public exploit

Unsigned application installation via signature verification bypass

Published Dec 16, 2022 · Updated Oct 27, 2024

Insufficient signature verification in PAX A930 PayDroid 7.1.1 Virgo V04.3.26T1 20210419 allows local users to install unsigned packages. The package installation path accepts an APK copied into /data/app with attacker-set permissions after the terminal reboots, without enforcing an authorized application signature. Exploitation requires shell access and root privileges; it permits unauthorized application installation on the payment terminal.
