ICEcoder Command Injection via Unescaped Filesystem Path

Publication date: 2026-09-10

Last updated on: 2026-09-10

Assigner: VulnCheck

Description
ICEcoder through 8.1 passes an unescaped filesystem path into a shell command in lib/properties.php, allowing authenticated users to inject OS commands through directory names. Attackers can create directories with shell metacharacters in their names and access the Properties function to execute arbitrary commands as the web-server user via popen().

Executive Summary

CVE-2026-64837 is an OS command injection vulnerability in ICEcoder version 8.1. It occurs in lib/properties.php when the application uses a user-controlled filesystem path in a popen() call without proper shell escaping. Authenticated users can create directories with shell metacharacters in their names, such as 'pwn2;id'. When the Properties function processes this directory, it constructs a shell command like '/usr/bin/du -sb /var/www/html/pwn2;id', where the semicolon executes the 'id' command. This allows arbitrary OS command execution under the web-server user's privileges.

Detection Guidance

Check for ICEcoder installations, particularly version 8.0 or 8.1. Inspect the lib/properties.php file for the use of popen() with unescaped user-controlled paths. Look for directories with shell metacharacters in names. Use commands like 'find /var/www -name "*[;|&]*"' to detect suspicious directory names.

Impact Analysis

This vulnerability allows attackers to execute arbitrary commands on the server with the privileges of the web-server user. They could read or modify files, access sensitive data, or further compromise the host. Since ICEcoder's Terminal feature is not required for exploitation, disabling it does not mitigate the issue. The impact depends on the web server's privileges but could be severe.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements under GDPR (data protection) and HIPAA (health information privacy). Unauthorized command execution may result in data breaches, unauthorized modifications, or exfiltration of regulated data, potentially leading to legal penalties, fines, or reputational damage for organizations subject to these regulations.

Mitigation Strategies

Upgrade ICEcoder to a patched version if available. If not, modify lib/properties.php to escape paths using escapeshellarg() before passing to popen(). Alternatively, replace shell commands with pure PHP functions for directory size calculation. Disable the Properties feature if not needed.
