Vulnerability from github – Published: 2021-08-30 17:22 – Updated: 2021-08-30 17:19

Summary

Improper Resource Shutdown or Release in TYPO3 extension

Details

Wrong usage of the TYPO3 FAL API results in copies of processed files being saved to the /var/transient/ folder of a TYPO3 website on every frontend request. This can result in Denial of Service, since the webspace may be filled up with image files simply by crafting a large amount of requests to the website.

Severity

7.5 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
