CVE-2022-47757 is a critical-severity flaw (CVSS 9.8) affecting imo. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In imo.im 2022.11.1051, a path traversal vulnerability delivered via an unsanitized deeplink can force the application to write a file into the application's data directory. This may allow an attacker to save a shared library under a special directory which the app uses to dynamically load modules. Loading the library can lead to arbitrary code execution.

imo imo DOWNGRADE

Affected: 2022.11.1051

Fixed in: no fixed release known

Safe to downgrade to: a release before 2022.11.1051

1. Check installed version

apt-cache policy imo || rpm -q imo || imo --version

2. No fixed release: DOWNGRADE to a release before 2022.11.1051 (Debian / Ubuntu)

apt-cache madison imo sudo apt install imo=<VERSION_BEFORE_2022.11.1051> sudo apt-mark hold imo

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list imo sudo dnf downgrade imo-<VERSION_BEFORE_2022.11.1051> sudo dnf versionlock add imo

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
