CVE-2024-52430 is a vulnerability identified in the Lis Video Gallery plugin developed by bublick, affecting versions up to and including 0.2.1. The issue is a deserialization of untrusted data vulnerability that allows object injection attacks. Deserialization vulnerabilities occur when an application deserializes data from untrusted sources without proper validation or sanitization, enabling attackers to inject malicious objects. In this case, the Lis Video Gallery plugin improperly processes serialized data, which can be crafted by an attacker to manipulate the application’s behavior. Object injection can lead to severe consequences such as remote code execution, privilege escalation, or data tampering, depending on the application context and the payload delivered. Although no exploits have been reported in the wild yet, the vulnerability is publicly disclosed and documented in the CVE database. The lack of a CVSS score indicates that the vulnerability is newly published and has not yet undergone formal severity assessment. However, given the nature of deserialization vulnerabilities and their history of exploitation, this flaw poses a significant risk. The vulnerability affects WordPress sites using the Lis Video Gallery plugin, which is used to manage and display video content. Attackers targeting vulnerable installations could compromise the affected systems by injecting malicious serialized objects, potentially leading to full system compromise or data breaches.

The potential impact of CVE-2024-52430 is substantial for organizations using the Lis Video Gallery plugin. Successful exploitation could allow attackers to execute arbitrary code on the web server, leading to full system compromise. This can result in unauthorized access to sensitive data, defacement of websites, deployment of malware, or use of compromised servers as pivot points for further attacks within an organization’s network. The integrity and availability of the affected web applications could be severely disrupted, causing operational downtime and reputational damage. Since the vulnerability involves object injection through deserialization, it may also facilitate privilege escalation or bypass of security controls. Organizations relying on WordPress-based video galleries for content delivery, marketing, or customer engagement are particularly at risk. The absence of known exploits in the wild currently reduces immediate threat levels but does not eliminate the risk, as attackers often develop exploits rapidly after public disclosure. The scope of affected systems is limited to those running the vulnerable plugin versions, but given WordPress’s widespread use, the number of potentially affected sites could be significant.

1. Immediately disable the Lis Video Gallery plugin if it is not essential to your operations until a patch is released. 2. Monitor official vendor channels and security advisories for updates or patches addressing CVE-2024-52430 and apply them promptly once available. 3. Implement strict input validation and sanitization on all data inputs, especially those involving serialized data, to prevent injection of malicious objects. 4. Restrict access to the plugin’s functionalities and serialized data endpoints to trusted users and IP addresses only, using web application firewalls (WAFs) or access control lists (ACLs). 5. Employ runtime application self-protection (RASP) or intrusion detection systems (IDS) to detect and block suspicious deserialization attempts. 6. Conduct regular security audits and code reviews focusing on serialization/deserialization logic in custom plugins or themes. 7. Maintain up-to-date backups of affected systems to enable rapid recovery in case of compromise. 8. Educate development and security teams about secure deserialization practices and the risks of object injection vulnerabilities.
