How to Fix CVE-2019-11512
To remediate this vulnerability, upgrade all affected Contao/contao dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade contao/contao to 4.4.39Upgrade contao/contao to 4.7.5Upgrade contao/core-bundle to 4.4.39Upgrade contao/core-bundle to 4.7.5Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for contao/contaoHow to Check if You Are Affected
To determine whether your application is affected by CVE-2019-11512, inspect your project dependencies for Contao/contao:
inspect dependencies for contao/contaoAnalyze the terminal output to locate any version of Contao/contao in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.39), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Contao/contao, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
