CVE-2026-25108 — FileZen Command Injection
Technical analysis of CVE-2026-25108, a critical FileZen OS command injection vulnerability allowing unauthenticated remote attackers to execute arbitrary system commands.
Buffer Overflow — When Memory Boundaries Are Exceeded
A buffer overflow is a memory corruption vulnerability that occurs when data exceeds the allocated memory boundary, potentially allowing attackers to overwrite adjacent memory and execute arbitrary code. This SECMONS glossary entry explains how buffer overflows occur, their impact, and how defenders should interpret related CVEs.
Deserialization Vulnerability — Unsafe Object Reconstruction Leading to Code Execution
A deserialization vulnerability occurs when untrusted data is deserialized without proper validation, potentially allowing attackers to manipulate object behavior or achieve remote code execution. This SECMONS glossary entry explains how insecure deserialization works, why it is dangerous, and how defenders should mitigate it.
File Inclusion (LFI/RFI) — Executing or Exposing Files via Improper Input Handling
File Inclusion vulnerabilities, including Local File Inclusion (LFI) and Remote File Inclusion (RFI), allow attackers to include unintended files in application execution flow. This SECMONS glossary entry explains how file inclusion works, how it differs from path traversal, and how defenders should mitigate it.
Sandbox Escape — Breaking Out of Application Isolation Boundaries
A sandbox escape occurs when an attacker bypasses application isolation mechanisms to execute code outside a restricted environment. This SECMONS glossary entry explains how sandboxing works, how escapes occur, and why sandbox escape vulnerabilities significantly increase exploitation impact.
Web Shell — Malicious Server-Side Backdoor for Remote Control
A Web Shell is a malicious script deployed on a web server that allows attackers to execute commands remotely. This SECMONS glossary entry explains how web shells are deployed, why they are difficult to detect, and how defenders can identify and remove them.
