Dabei geht es um die Funktion gen_rsa_keys der Datei common/crypto.py. Durch das Manipulieren mit unbekannten Daten kann eine inadequate encryption strength-Schwachstelle ausgenutzt werden. Die Umsetzung des Angriffs kann dabei \u00fcber das Netzwerk erfolgen. Die Komplexit\u00e4t eines Angriffs ist eher hoch. Das Ausnutzen gilt als schwierig. Dieses Produkt verzichtet auf eine Versionierung und verwendet stattdessen Rolling Releases. Deshalb sind keine Details zu betroffenen oder zu aktualisierende Versionen vorhanden."

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.
