CVE-2024-37502 is a security vulnerability classified as deserialization of untrusted data found in the wpweb WooCommerce Social Login plugin, specifically affecting all versions up to and including 2.6.3. Deserialization vulnerabilities occur when an application deserializes data from untrusted sources without proper validation or sanitization, allowing attackers to manipulate the serialized data to execute arbitrary code or cause unexpected behavior. In this case, the WooCommerce Social Login plugin processes serialized data related to user login or social authentication features. An attacker can craft malicious serialized payloads and send them to the plugin, which then deserializes this data insecurely. This can lead to remote code execution, privilege escalation, or other attacks compromising the WordPress site. The vulnerability does not require user interaction but does require the attacker to send malicious requests to the vulnerable endpoint. Although no public exploits have been reported yet, the nature of deserialization vulnerabilities typically makes them highly dangerous. The vulnerability affects a widely used WordPress plugin that integrates social login capabilities into WooCommerce, a popular e-commerce platform. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. The vulnerability was published on July 9, 2024, and was reserved in early June 2024. No patches or fixes are linked yet, indicating users should monitor vendor updates closely.

The impact of CVE-2024-37502 is potentially severe for organizations using WooCommerce Social Login on their WordPress e-commerce sites. Successful exploitation could allow attackers to execute arbitrary code on the web server, leading to full site compromise. This could result in theft of customer data, including personal and payment information, defacement of websites, insertion of malicious content, or use of the compromised server as a pivot point for further attacks. The integrity of the e-commerce platform and customer trust would be significantly damaged. Availability could also be affected if attackers disrupt services or deploy ransomware. Since WooCommerce powers a large portion of online stores globally, the scope of affected systems is broad. The ease of exploitation is moderate to high given that no authentication or user interaction is explicitly required, only the ability to send crafted requests to the vulnerable plugin. Organizations without timely patching or mitigations are at risk of targeted or opportunistic attacks, especially as exploit code may emerge in the future.

1. Immediately monitor for updates or patches released by wpweb for WooCommerce Social Login and apply them as soon as available. 2. If patches are not yet available, consider temporarily disabling the WooCommerce Social Login plugin to eliminate the attack surface. 3. Implement web application firewall (WAF) rules to detect and block suspicious serialized payloads or anomalous requests targeting the social login endpoints. 4. Conduct thorough input validation and sanitization on any data processed by the plugin, if custom modifications are possible. 5. Restrict access to the plugin’s endpoints by IP whitelisting or authentication where feasible. 6. Regularly audit logs for unusual activity related to social login requests. 7. Educate site administrators on the risks of deserialization vulnerabilities and the importance of timely patching. 8. Maintain regular backups of the website and database to enable recovery in case of compromise. 9. Consider deploying runtime application self-protection (RASP) tools that can detect and block exploitation attempts in real time.
