Introduction: As a Threat Intelligence Analyst at Tamer Elgayar Corporate, I was assigned a high-priority task to investigate recent vulnerabilities affecting Apache and MySQL, as our company is launching a new webserver "Enzel ya Metdala3". The goal was to identify critical CVEs from the last few months, analyze their potential impact on our infrastructure, and provide actionable insights for mitigation..

Objective: The main objectives of this task were to:

  • Research at least three recent CVEs impacting Apache and MySQL.
  • Assess how these vulnerabilities could affect our organization.
  • Identify available proof-of-concept (PoC) exploits where applicable.
  • Provide recommendations to strengthen the security of our webserver prior to launch.

Let's get Started!

CVE-2025–30065->CVE-2025–30065 | CVE

Title:

Apache Parquet Java: Arbitrary code execution in the parquet-avro module when reading an Avro schema from a Parquet file metadata, Published: 2025–04–01.

Description:

A vulnerability exists in the parquet-avro component of Apache Parquet, which is responsible for converting and reading data between Parquet files and Avro schemas. Versions 1.15.0 and earlier contain a flaw in the schema parsing process, allowing an attacker to supply a malicious Avro file that can lead to arbitrary code execution during data processing. Users are strongly advised to upgrade to version 1.15.1, which fully addresses the issue.

CVE-2025–62611-> CVE Record: CVE-2025–62611

Title:

aiomysql allows arbitrary access to client files through vulnerability of a malicious MySQL server, Published: 2025–10–22.

Description:

aiomysql is a Python library that provides asynchronous (asyncio-based) access to MySQL databases. Before version 0.3.0, the library did not properly validate client-side settings before sending local files, allowing a rogue MySQL server to request and obtain arbitrary files from the client machine using a forged LOAD_LOCAL packet. This vulnerability was patched in version 0.3.0. Related to CVE-2019–2503.
