Description

Insufficient input sanitization in ejson2env

Summary

The ejson2env tool has a vulnerability related to how it writes to stdout. Specifically, the tool is intended to write an export statement for environment variables and their values. However, due to inadequate output sanitization, there is a potential risk where variable names or values may include malicious content, resulting in additional unintended commands being output to stdout. If this output is improperly utilized in further command execution, it could lead to command injection vulnerabilities, allowing an attacker to execute arbitrary commands on the host system.

Details

The vulnerability exists because environment variables are not properly sanitized during the decryption phase, which enables malicious keys or encrypted values to inject commands.

Impact

An attacker with control over .ejson files can inject commands in the environment where source $(ejson2env) or eval ejson2env are executed.

Mitigation

  • Update to a version of ejson2env that sanitizes the output during decryption or
  • Do not use ejson2env to decrypt untrusted user secrets or
  • Do not evaluate or execute the direct output from ejson2env without removing nonprintable characters.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is high, an attacker needs administrative privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: High — administrative rights are needed first.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.

Weakness class

CVE-2025-48069 is classified as CWE-78: OS Command Injection. Untrusted input reaches a shell command without neutralisation, so an attacker can run arbitrary operating system commands.
