CVE-2023-53982 is a high-severity flaw (CVSS 7.5) affecting pmb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

PMB 7.4.6 contains a SQL injection vulnerability in the id parameter of the storage module (categ=storage) of the opac_css/ajax.php endpoint that allows remote attackers to manipulate database queries. Attackers can exploit the unsanitized 'id' parameter by injecting conditional sleep statements to extract information or perform time-based blind SQL injection attacks.

sigb pmb DOWNGRADE

Affected: 7.4.6

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.4.6

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 7.4.6 (Debian / Ubuntu)

apt-cache madison pmb sudo apt install pmb=<VERSION_BEFORE_7.4.6> sudo apt-mark hold pmb

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

dnf --showduplicates list pmb sudo dnf downgrade pmb-<VERSION_BEFORE_7.4.6> sudo dnf versionlock add pmb

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.
