Summary
Problem
The plaintext value of $GLOBALS['SYS']['encryptionKey'] was displayed in the editing forms of the TYPO3 Install Tool user interface. This allowed attackers to utilize the value to generate cryptographic hashes used for verifying the authenticity of HTTP request parameters. Exploiting this vulnerability requires an administrator-level backend user account with system maintainer permissions.

Impact
CVE-2024-25119 has a CVSS score of 4.9 (Medium). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (8.7.57, 9.5.46, 10.4.43, 11.5.35, 12.4.11, 13.0.1); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
Update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described.
Frequently Asked Questions
- What is CVE-2024-25119? CVE-2024-25119 is a medium-severity security vulnerability in typo3/cms-core (composer), affecting versions >= 8.0.0, <= 8.7.56. It is fixed in 8.7.57, 9.5.46, 10.4.43, 11.5.35, 12.4.11, 13.0.1.
- How severe is CVE-2024-25119? CVE-2024-25119 has a CVSS score of 4.9 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of typo3/cms-core are affected by CVE-2024-25119? typo3/cms-core (composer) versions >= 8.0.0, <= 8.7.56 is affected.
- Is there a fix for CVE-2024-25119? Yes. CVE-2024-25119 is fixed in 8.7.57, 9.5.46, 10.4.43, 11.5.35, 12.4.11, 13.0.1. Upgrade to this version or later.
- Is CVE-2024-25119 exploitable, and should I be worried? Whether CVE-2024-25119 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-25119 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
