CVE-2024-56283 is a vulnerability in the plainware Locatoraid Store Locator plugin, specifically versions up to and including 3.9.50. The issue stems from insecure deserialization of untrusted data, which allows an attacker to perform object injection. Deserialization vulnerabilities occur when applications deserialize data without properly validating or sanitizing it, enabling attackers to inject malicious objects that can alter program flow or execute arbitrary code. In this case, the Locatoraid Store Locator plugin processes serialized data inputs that can be manipulated by an attacker to inject crafted objects. This can lead to severe consequences such as remote code execution, privilege escalation, or data manipulation depending on the plugin's privileges and integration. The vulnerability does not require authentication, meaning any unauthenticated attacker with access to the vulnerable input vector can attempt exploitation. Although no known exploits have been reported in the wild yet, the lack of patches and the nature of the vulnerability make it a significant risk. The plugin is commonly used in WordPress environments to provide store locator functionality, often integrated into e-commerce or retail websites, increasing the potential attack surface. The absence of a CVSS score requires an assessment based on impact and exploitability factors, which indicate a high severity level. The vulnerability was published on January 7, 2025, with the initial reservation on December 18, 2024, by Patchstack, a known security research entity. No official patches or mitigation links have been provided at this time, emphasizing the need for proactive defensive measures.

The potential impact of CVE-2024-56283 is significant for organizations using the Locatoraid Store Locator plugin. Successful exploitation can lead to remote code execution, allowing attackers to execute arbitrary commands on the affected server. This compromises confidentiality by potentially exposing sensitive data, integrity by allowing unauthorized data modification, and availability by enabling denial-of-service conditions or system crashes. Since the plugin is often deployed on public-facing websites, attackers can exploit this vulnerability remotely without authentication, increasing the risk of widespread attacks. The impact extends to the broader ecosystem, including e-commerce platforms, retail chains, and any business relying on store locator functionality. Compromise of these systems could result in data breaches, website defacement, malware distribution, or lateral movement within corporate networks. The lack of known exploits currently provides a window for organizations to remediate before active exploitation occurs, but the risk remains high given the ease of exploitation and potential damage.

1. Monitor for official patches or updates from plainware and apply them immediately once released. 2. In the absence of patches, restrict access to the plugin's input endpoints by implementing web application firewall (WAF) rules that block suspicious serialized data or unexpected input patterns. 3. Employ strict input validation and sanitization to prevent untrusted data from being deserialized. 4. Disable or limit the use of PHP object deserialization in the plugin if configurable, or use safer serialization formats such as JSON where possible. 5. Conduct code audits and penetration testing focused on deserialization vulnerabilities within the plugin and related components. 6. Isolate the plugin environment using containerization or sandboxing to limit the impact of potential exploitation. 7. Monitor logs and network traffic for unusual activity indicative of exploitation attempts. 8. Educate development and security teams about the risks of insecure deserialization and best practices for secure coding. 9. Consider temporary removal or replacement of the plugin if immediate patching is not feasible and risk is unacceptable.
