HIGH 7.5DOWNGRADE

CVE-2006-4545 is a high-severity flaw (CVSS 7.5) affecting modulebased cms. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

PHP remote file inclusion vulnerability in ModuleBased CMS Pre-Alpha allows remote attackers to execute arbitrary PHP code via the _SERVER parameter in (1) admin/avatar.php, (2) libs/archive.class.php, (3) libs/login.php, (4) libs/profiles.class.php, and (5) libs/profile/proccess.php. NOTE: CVE disputes this claim, as the _SERVER array and the _SERVER[DOCUMENT_ROOT] index are controlled by PHP and cannot be manipulated by an attacker

modulebased cms modulebased cms DOWNGRADE

Affected: pre-alpha

Fixed in: no fixed release known

Safe to downgrade to: a release before pre-alpha

1. Check installed version

apt-cache policy modulebased-cms || rpm -q modulebased-cms || modulebased-cms --version

2. No fixed release: DOWNGRADE to a release before pre-alpha (Debian / Ubuntu)

apt-cache madison modulebased-cms sudo apt install modulebased-cms=<VERSION_BEFORE_pre-alpha> sudo apt-mark hold modulebased-cms

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

dnf --showduplicates list modulebased-cms sudo dnf downgrade modulebased-cms-<VERSION_BEFORE_pre-alpha> sudo dnf versionlock add modulebased-cms

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.
