What This Vulnerability Is

A vulnerability was found in rickxy Hospital Management System up to 88a4290d957dc5bdde8a56e5ad451ad14f7f90f4. Affected is an unknown function of the file /backend/admin/his_admin_account.php. The manipulation of the argument ad_dpic results in unrestricted upload. The attack can be executed remotely. The exploit has been made public and could be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable.

The National Vulnerability Database assigned this issue a CVSS base score of 7.3, placing it in the HIGH category. The identifier CVE-2026-6602 was published on 2026-04-20T04:16:58.933.

Who Is Affected

Based on the vulnerability data published by NVD, the following products and configurations are identified as affected:

  • Specific affected products are listed in the NVD entry. Review the CPE data for your stack.

If your organization uses any of the above, this vulnerability applies to your environment. Even if your specific version is not listed, review the full CPE match data to confirm.

What Attack Traffic Looks Like

Illustrative patterns for defensive detection. Not a working exploit.

File upload attacks place executable content in web-accessible directories. Watch for:

POST /upload HTTP/1.1
Content-Type: multipart/form-data
filename="shell.php"
filename="image.php.jpg"
filename="exploit.jsp"
filename="cmd.aspx"

How to Detect It

Sigma Rule

title: Executable File Upload to Web Directory
id: auto-cwe434-detection
status: experimental
description: Detects upload of potentially executable files to web-accessible directories.
logsource:
  category: webserver
detection:
  selection:
    cs-uri-stem|contains: '/upload'
    cs-method: 'POST'
  keywords:
    cs-uri-query|re: '\.(php|jsp|aspx|cgi|pl|py|sh|exe|bat|cmd)'
  condition: selection or keywords
level: high

IOC Hunt List

  • New .php/.jsp/.aspx/.cgi files in upload or media directories
  • Files with double extensions (image.php.jpg) in web-accessible paths
  • Web server process executing shell commands after file upload requests
  • Unusual POST requests to upload endpoints with large Content-Length

What to Do About It

Here is what we recommend, in order of priority:

  1. Check your exposure. Determine whether the affected software or component is present in your environment. Asset inventories and software composition analysis (SCA) tools are the fastest route.
  2. Apply the patch. If a vendor patch or updated version is available, apply it. Check the references below for vendor advisories.
  3. Mitigate if patching is not immediate. If you cannot patch right now, evaluate whether network segmentation, access control changes, or configuration adjustments reduce the attack surface for this specific vulnerability.
  4. Monitor for exploitation. Check whether proof-of-concept exploit code exists. The CISA Known Exploited Vulnerabilities catalog tracks actively exploited CVEs.
  5. Document your response. Record what you checked, when you patched, and what residual risk remains. This matters for compliance and for incident response if this vulnerability is exploited later.

Triage Quick Start

Run as administrator. Collect artifacts before applying patches or making changes:

# Linux/Unix systems
tar czf /tmp/triage-$(hostname)-$(date +%s).tgz \
  /var/log/syslog /var/log/auth.log /var/log/messages \
  /var/log/secure /var/log/apache2/ /var/log/nginx/ \
  /etc/passwd /etc/shadow \
  /root/.bash_history \
  /home/*/.bash_history \
  /tmp/ /var/tmp/ 2>/dev/null

# Windows systems (PowerShell)
# Compress-Archive -Path C:\Windows\System32\winevt\Logs\*,C:\inetpub\logs\* -DestinationPath C:\triage.zip

Why This Matters for Companies Without Security Teams

A CVSS score of 7.3 means this vulnerability is straightforward to exploit, likely to cause significant damage, or both. For startups and small companies operating without a dedicated security team, vulnerabilities at this severity level represent real operational risk rather than theoretical concern.

The challenge is not awareness. Vulnerability databases are public. The challenge is triage: understanding whether a given CVE affects your specific stack, and knowing what to do about it before an attacker does. If you lack the internal capacity to perform that assessment, an external review of your exposure is a concrete next step.

Sherlock Forensics provides vulnerability assessment and penetration testing for organizations that need to understand their attack surface without building a full internal security function.
