Title

Request smuggling in aiohttp

Summary

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel). These bugs have been addressed in commit `d5c12ba89` which has been included in release version 3.8.6. Users are advised to upgrade. There are no known workarounds for these issues.

CVE-2023-47627

In Oracle Siebel CRM existieren mehrere Schwachstellen. Durch Ausnutzung dieser Schwachstellen kann ein entfernter, anonymer oder authentisierter Angreifer die Vertraulichkeit, Integrität und Verfügbarkeit gefährden. Für die Ausnutzung dieser Schwachstellen ist keine Benutzerinteraktion notwendig. Oracle veröffentlicht keine weiteren Details zu diesen Schwachstellen (außer der Information in der Risiko Matrix im Oracle Advisory zum Critical Patch Update, siehe Link unten in diesem Advisory). Aufgrund der knappen Informationslage erfolgt die Bewertung der Schadenshöhe ausschließlich auf Basis der CVSS Impact Matrix. Der Maximalwert für diese Produkte ist "HIGH" für "Confidentiality", "Integrity" und "Availability" über alle Schwachstellen aggregiert und bewirkt damit eine Bewertung mit dem Wert "HOCH" für die Schadenshöhe.
