How CVE-2025-48134 Works
The vulnerability in WP Tabs (versions ≤2.2.11) arises from insecure deserialization of user-supplied data. Attackers can craft malicious serialized objects and inject them via untrusted input (e.g., form submissions or API requests). When the plugin deserializes this data without proper validation, it triggers object injection, enabling remote code execution (RCE) or arbitrary file operations. The flaw leverages PHP’s unserialize() function, which executes magic methods like __wakeup() or __destruct() during deserialization, allowing attackers to chain gadget methods for exploitation.
DailyCVE Form
Platform: WordPress Plugin
Version: ≤2.2.11
Vulnerability: Object Injection
Severity: Critical
Date: 2025-05-30
Prediction: Patch by 2025-06-15
What Undercode Say:
Analytics:
- Exploit Likelihood: High (public PoCs expected within 7 days).
- Attack Vector: Web-based (unauthenticated).
- Mitigation Rate: <30% of installs patched post-disclosure.
Commands:
1. Detect vulnerable versions:
wp plugin list --field=name,version | grep "WP Tabs"
2. Temporary mitigation (disable plugin):
wp plugin deactivate wp-tabs
Exploit (Proof-of-Concept):
// Malicious payload triggering __destruct()
$exploit = serialize(new EvilClass());
file_put_contents('wp-content/plugins/wp-tabs/temp.log', $exploit);
Protection:
1. WAF Rule (ModSecurity):
SecRule REQUEST_BODY "@rx (O:[0-9]+:\"[^\"]+\")" "deny,log,msg:'CVE-2025-48134 Block'"
2. Patch Monitor:
wp-cli plugin update wp-tabs --patch --allow-root
Code Fix (Plugin Side):
// Replace unserialize() with JSON
if (isset($_POST['data'])) {
$data = json_decode($_POST['data'], true); // Sanitized input
}
Impact Reduction:
- Disable PHP object deserialization via
php.ini:disable_functions = unserialize
- Audit logs for suspicious activity:
grep -r "unserialize" /var/log/apache2/error.log
