Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-1286: Improper Validation of Syntactic Correctness of Input, where the product receives input that is expected to be well-formed - i.e., to comply with a certain syntax - but it does not validate or incorrectly validates that the input complies with the syntax. In Typo3/cms backend, software state validation or input boundaries are circumvented during processing.
