Remote-Code-Execution
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.
Command Injection — Executing Arbitrary System Commands via Application Input
Command Injection is a vulnerability that allows attackers to execute arbitrary operating system commands by manipulating application input. This SECMONS glossary entry explains how command injection works, its impact, how it differs from SQL injection, and how defenders can prevent it.
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.
Exploit Chain — Linking Multiple Vulnerabilities for Full Compromise
An Exploit Chain is a sequence of vulnerabilities or techniques combined to achieve full system compromise. This SECMONS glossary entry explains how exploit chains work, why single CVSS scores may underestimate risk, and how defenders should assess chained exploitation.
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.
Remote Code Execution (RCE) — What It Means and Why It’s One of the Most Dangerous Vulnerability Impacts
Remote Code Execution (RCE) allows an attacker to execute arbitrary code on a target system from a remote location. This SECMONS glossary entry explains how RCE occurs, how it differs from other impacts, how it is typically exploited, and why RCE-class vulnerabilities demand immediate attention.
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.
CVE-2021-44228 — Log4Shell Remote Code Execution in Apache Log4j
CVE-2021-44228 (Log4Shell) is a critical remote code execution vulnerability in Apache Log4j 2 that enabled unauthenticated attackers to execute arbitrary code via JNDI lookups. This record provides verified technical analysis, exploitation context, impact assessment, and defensive guidance.
