CVE-2024-46292 is a high-severity flaw (CVSS 7.5) affecting modsecurity. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A buffer overflow in modsecurity v3.0.12 allows attackers to cause a Denial of Service (DoS) via a crafted input inserted into the name parameter. NOTE: this is disputed by the Supplier because it cannot be reproduced. Also, the product's documentation indicates that it is not guaranteed to be usable with very large values of SecRequestBodyNoFilesLimit (which are required by the claimed issue).

trustwave modsecurity DOWNGRADE

Affected: 3.0.12

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.0.12

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.0.12 (Debian / Ubuntu)

apt-cache madison modsecurity sudo apt install modsecurity=<VERSION_BEFORE_3.0.12> sudo apt-mark hold modsecurity

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

dnf --showduplicates list modsecurity sudo dnf downgrade modsecurity-<VERSION_BEFORE_3.0.12> sudo dnf versionlock add modsecurity

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.
