Inappropriate coding practices - relative path command

Description​

Files are found that reference executables within the system that make use of relative path definition. When a binary that makes use of relative paths is executed, they call the executables of environment variables or PATH, which an attacker can manipulate, being able to compromise the system completely.

Impact​

Obtain uncontrolled privileges.

Recommendation​

Using absolute paths for calling executables.

Threat​

Authenticated attacker with local access to the compromised system.

Expected Remediation Time​

⌚ 60 minutes.
