Executive Summary

HaPe PKH version 1.1 contains an arbitrary file upload vulnerability that allows authenticated attackers to bypass file type validation and upload malicious files.

Attackers can upload PHP files through multiple endpoints such as aksi_foto.php, aksi_user.php, and aksi_kecamatan.php.

This enables the execution of arbitrary code on the server, potentially compromising the system.

Detection Guidance

This vulnerability can be detected by checking for the presence of uploaded PHP files in directories related to the HaPe PKH application, especially through the endpoints aksi_foto.php, aksi_user.php, and aksi_kecamatan.php.

You can look for suspicious PHP files in upload directories such as /hape-pkh/gambar-konten/ which may indicate exploitation attempts.

Suggested commands to detect potential exploitation include:

• Using find command on the server to locate PHP files in upload directories: find /path/to/hape-pkh/ -type f -name "*.php"
• Checking web server logs for POST requests to aksi_foto.php, aksi_user.php, and aksi_kecamatan.php endpoints that may indicate file uploads.
• Using network monitoring tools to detect unusual HTTP POST requests to these endpoints.

Mitigation Strategies

Immediate mitigation steps include restricting or disabling file uploads through the vulnerable endpoints (aksi_foto.php, aksi_user.php, and aksi_kecamatan.php) until a patch or fix is applied.

Implement strict server-side validation to ensure only allowed file types are accepted, preventing PHP or other executable files from being uploaded.

Review and remove any suspicious PHP files found in upload directories to prevent code execution.

Limit user privileges to reduce the risk of authenticated attackers exploiting the vulnerability.

Monitor server logs and network traffic for signs of exploitation attempts.
