CVE-2019-20059 is a high-severity flaw (CVSS 8.8) affecting yetishare. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

payment_manage.ajax.php and various *_manage.ajax.php in MFScripts YetiShare 3.5.2 through 4.5.4 directly insert values from the sSortDir_0 parameter into a SQL string. This allows an attacker to inject their own SQL and manipulate the query, typically extracting data from the database, aka SQL Injection. NOTE: this issue exists because of an incomplete fix for CVE-2019-19732.

mfscripts yetishare UPGRADE

Affected: >= 3.5.2 and <= 4.5.4

Fixed in: newer than 4.5.4

Safe to downgrade to: a release before 3.5.2

1. Check installed version

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

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.5.2 (Debian / Ubuntu)

apt-cache madison yetishare sudo apt install yetishare=<VERSION_BEFORE_3.5.2> sudo apt-mark hold yetishare

dnf --showduplicates list yetishare sudo dnf downgrade yetishare-<VERSION_BEFORE_3.5.2> sudo dnf versionlock add yetishare

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.
