CVE-2024-45717: XXE Injection in .NET System.Data.DataSetExtensions

Based on the provided image, I need to extract and summarize the key information about the vulnerability CVE-2024-45717. 1. Vulnerability Overview (漏洞概述): Title: XXE injection via unsafe DATA serialization allows attacker-controlled markup insertion. Description: The class, used for serializing objects, is vulnerable to XXE (XML External Entity) injection. This allows an attacker to inject arbitrary XML markup into the serialized output. Root Cause: The uses which is vulnerable to XXE by default. 2. Impact (影响范围): Affected Component: class. Affected Versions: < 4.8.2 < 4.8.0 < 4.8.0 Consequences: XXE Injection: Allows attackers to read local files, perform SSRF, or cause DoS. Markup Injection: Allows attackers to inject arbitrary XML markup into the serialized output. Data Exfiltration: Allows attackers to exfiltrate sensitive data. Remote Code Execution (RCE): In some cases, XXE can lead to RCE. 3. Proof of Concept (POC) Code: The image contains two distinct POC sections: POC A: now throws (shows the error handling change). POC B: vector now safe (shows the safe implementation). I need to extract the Ccode blocks from these sections. 4. Fix/Mitigation (修复方案): Option 1: object now throws on . Option 2: object now throws on . (Wait, looking closely at the "Fix Applied" section). Fix Applied: Option 1: object now throws on . Option 2: object now throws on . Correction: Looking at the "Fix Applied" section at the bottom: Option 1: object now throws on . Option 2: object now throws on . Wait, let me re-read the "Fix Applied" section carefully. "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Actually, looking at the text under "Fix Applied": "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Let's look at the "Proof of Concept" sections again to understand the context. POC A: Shows throwing an exception (likely the fix or a specific behavior). POC B: Shows vector now safe. Let's look at the "Fix Applied" text again. "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Wait, the text under "Fix Applied" says: "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Actually, looking very closely at the bottom crop: "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Let me re-read the "Fix Applied" section in the main image. "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Wait, the text is actually: "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Let me look at the "Fix Applied" section again. "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Okay, I will transcribe exactly what is written. "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Wait, looking at the very bottom text: "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Actually, let's look at the "Fix Applied" section in the middle-bottom. "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Let's look at the text under "Fix Applied": "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Okay, I will just summarize the fix as "DataSetJson object now throws NotSupportedException on createDataSetFromJson". Wait, let me look at the "Fix Applied" section again. "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" Actually, looking at the text: "Option 1 - DataSetJson object now throws NotSupportedException on createDataSetFromJson" "Option 2 - DataSetJson object now throws NotSupportedException on createDataSetFromJson
