CRITICAL 9.8REMOTEUPGRADE

CVE-2009-1936 is a critical-severity flaw (CVSS 9.8) affecting cpcommerce. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

_functions.php in cpCommerce 1.2.x, possibly including 1.2.9, sends a redirect but does not exit when it is called directly, which allows remote attackers to bypass a protection mechanism to conduct remote file inclusion and directory traversal attacks, execute arbitrary PHP code, or read arbitrary files via the GLOBALS[prefix] parameter, a different vector than CVE-2003-1500.

cpcommerce project cpcommerce UPGRADE

Affected: >= 1.2.0 and <= 1.2.9

Fixed in: newer than 1.2.9

Safe to downgrade to: a release before 1.2.0

1. Check installed version

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

2. UPGRADE to newer than 1.2.9 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade cpcommerce

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade cpcommerce

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 1.2.0 (Debian / Ubuntu)

apt-cache madison cpcommerce sudo apt install cpcommerce=<VERSION_BEFORE_1.2.0> sudo apt-mark hold cpcommerce

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list cpcommerce sudo dnf downgrade cpcommerce-<VERSION_BEFORE_1.2.0> sudo dnf versionlock add cpcommerce

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.

Public exploits and detection

Public code exists for this CVE. Treat unpatched systems as at risk, and only run PoCs in a lab.
