CVE-2025-54785

8.8 HIGH

📋 TL;DR

SuiteCRM versions 7.14.6 and 8.8.0 contain an insecure deserialization vulnerability where user input is passed directly to PHP's unserialize() function without proper validation. This allows attackers to execute arbitrary code, potentially leading to complete system compromise. All organizations running these vulnerable SuiteCRM versions are affected.

💻 Affected Systems

Products:
  • SuiteCRM
Versions: 7.14.6 and 8.8.0
Operating Systems: All platforms running PHP
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of affected versions are vulnerable regardless of configuration

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to full system takeover, data exfiltration, ransomware deployment, and cryptomining operations

🟠

Likely Case

Privilege escalation, sensitive data exposure, and unauthorized access to CRM data

🟢

If Mitigated

Limited impact if proper input validation and WAF rules are in place

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Insecure deserialization vulnerabilities are commonly exploited and weaponization is likely given the high CVSS score

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 7.14.7 and 8.8.1

Vendor Advisory: https://github.com/SuiteCRM/SuiteCRM/security/advisories/GHSA-53cp-mpfw-qj67

Restart Required: No

Instructions:

1. Backup your SuiteCRM installation and database. 2. Download the patched version (7.14.7 or 8.8.1) from the official SuiteCRM repository. 3. Follow the SuiteCRM upgrade documentation for your version. 4. Verify the upgrade completed successfully.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement custom input validation to sanitize user input before deserialization

WAF Rule Implementation

all

Deploy web application firewall rules to block serialized object payloads

🧯 If You Can't Patch

  • Isolate SuiteCRM instance from internet access and restrict to internal network only
  • Implement strict network segmentation and monitor for suspicious deserialization attempts

🔍 How to Verify

Check if Vulnerable:

Check SuiteCRM version in admin panel or by examining the version.php file in the installation directory

Check Version:

grep 'suitecrm_version' /path/to/suitecrm/version.php

Verify Fix Applied:

Verify version is 7.14.7 or 8.8.1 or higher, and test input validation on user-supplied data

📡 Detection & Monitoring

Log Indicators:

  • Unusual PHP unserialize() calls
  • Suspicious POST requests with serialized data
  • Unexpected file creation or process execution

Network Indicators:

  • HTTP requests containing serialized PHP objects
  • Unusual outbound connections from SuiteCRM server

SIEM Query:

source="suitecrm.logs" AND ("unserialize" OR "O:" OR "a:" OR "s:" OR "i:") AND status=200
