CWE-95Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')

Description

Common consequences· 5

• Confidentiality — Read Files or Directories, Read Application Data
  The injected code could access restricted data / files.
• Access Control — Bypass Protection Mechanism
  In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
• Access Control — Gain Privileges or Assume Identity
  Injected code can access resources that the attacker is directly prevented from accessing.
• Integrity / Confidentiality / Availability / Other — Execute Unauthorized Code or Commands
  Code injection attacks can lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing. Additionally, code injection can often result in the execution of arbitrary code or at least modify what code can be executed.
• Non-Repudiation — Hide Activities
  Often the actions performed by injected control code are unlogged.

Potential mitigations· 4

• [Architecture and Design, Implementation]If possible, refactor your code so that it does not need to use eval() at all.
