CVE-2024-8392 is a Local File Inclusion vulnerability classified under CWE-98 affecting the WordPress Post Grid Layouts with Pagination – Sogrid plugin in all versions up to 1.5.2. The vulnerability arises from improper control of the filename used in an include or require statement within the plugin's PHP code, specifically via the 'tab' parameter. Authenticated attackers with Administrator-level privileges can manipulate this parameter to include arbitrary files from the server, which can contain malicious PHP code. This enables execution of arbitrary code on the web server, potentially leading to full system compromise. The vulnerability also allows bypassing access controls and accessing sensitive information stored on the server. Additionally, the flaw can be exploited through CSRF techniques, which means an attacker can trick an authenticated administrator into triggering the exploit without their direct intent. The vulnerability does not require user interaction beyond authentication but does require high privileges, limiting the attacker scope to those with admin access. The CVSS 3.1 score of 7.2 reflects network attack vector, low attack complexity, high privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No patches or fixes are currently listed, so mitigation relies on access control and monitoring until updates are released.

The impact of CVE-2024-8392 is significant for organizations using the affected WordPress plugin. Successful exploitation can lead to remote code execution on the web server, allowing attackers to execute arbitrary PHP code, which can compromise the entire hosting environment. This can result in data breaches, defacement, malware deployment, or pivoting to internal networks. Since the vulnerability requires administrator-level access, the primary risk is from insider threats or compromised admin accounts. However, the ability to exploit via CSRF increases risk by enabling attackers to leverage social engineering to exploit trusted users. The compromise of WordPress sites using this plugin can affect website availability, integrity of content, and confidentiality of stored data. Organizations relying on this plugin for content display or e-commerce may face operational disruption and reputational damage. The lack of known public exploits currently reduces immediate widespread threat but does not eliminate risk, especially in targeted attacks.

To mitigate CVE-2024-8392, organizations should immediately restrict administrator-level access to trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of account compromise. Monitoring and logging administrative actions on WordPress sites can help detect suspicious activities indicative of exploitation attempts. Until an official patch or update is released by the plugin vendor, consider disabling or removing the vulnerable plugin if feasible. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the 'tab' parameter or unusual file inclusion attempts. Educate administrators about the risk of CSRF attacks and encourage safe browsing practices to avoid social engineering exploitation. Regularly back up website data and server configurations to enable recovery in case of compromise. Once a patch is available, apply it promptly and verify the update resolves the vulnerability. Additionally, conduct periodic security assessments of WordPress plugins and themes to identify and remediate vulnerabilities proactively.
