CVE-2024-9539

Es besteht eine Schwachstelle in GitHub Enterprise Server. Dieser Fehler existiert wegen einer unsachgemäßen Validierung von Asset-URLs in der Komponente zur Dateiverarbeitung. Ein entfernter, authentifizierter Angreifer kann diese Schwachstelle ausnutzen, indem er eine bösartige SVG-Datei hochlädt und einen Benutzer dazu bringt, auf die Asset-URL zu klicken, was zum Abrufen von Metadateninformationen über den Benutzer führt. Diese Informationen können dann verwendet werden, um eine überzeugende Phishing-Seite zu erstellen.

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.
