Lucee CVE-2024-55354 Security Advisory April 2025

High
zspitzer published GHSA-8r7v-h3xv-fvr4 Apr 8, 2025

Package

Lucee Server

Affected versions

< 5.4.7.3, < 6.1.1.18

Patched versions

5.4.7.3, 6.1.1.118

Description

Impact

Lucee is vulnerable to a protection mechanism failure that can let an attacker run code that would be expected to be blocked and access resources that would be expected to be protected.

This patch is strongly recommended for multi-tenant and shared hosting environments.

To be clear, this is not a Lucee Admin vulnerability and the majority of Lucee installations will not be vulnerable.

If you are using your own VPS / Server, i.e you have root or Administrator access, it is unlikely you are using shared hosting, if in doubt contact your Hosting provider / System Admin to confirm.

Patches

Lucee 6.1.1.118 and newer already support this mitigation

The mitigation has been backported to the 5.4.7.3 LTS stable release.

Workarounds

This behaviour can be disabled by setting the following Java System Property or Environment Variable and restarting Lucee

· System property: -Dlucee.compiler.block.bytecode=true
· Environment variable: LUCEE_COMPILER_BLOCK_BYTECODE=true

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
