On January 16, 2025, a critical vulnerability was identified in the MercadoLibre Integration plugin (version <= 1.1), classified as a Cross-Site Request Forgery (CSRF) vulnerability. This vulnerability allows stored cross-site scripting (XSS), posing a significant risk to organizations utilizing this plugin. With a CVSS score of 7.1, this high-severity vulnerability necessitates immediate attention and remediation to prevent potential exploitation.
The vulnerability is characterized by low attack complexity and requires no privileges for exploitation, making it accessible to a wide range of attackers. User interaction is required, as the attack vector is network-based, heightening the risk for organizations dependent on this integration for their e-commerce operations.
Risk to organizations includes unauthorized access and manipulation of user data, which could lead to data breaches or further attacks. Given the prevalent use of the MercadoLibre Integration plugin, organizations should prioritize patching immediately to safeguard against potential threats.
Currently, there is no public exploit confirmed, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, given the nature of the vulnerability and its potential impact, security teams should remain vigilant.
Organizations should remain proactive in their security posture, ensuring that all systems are updated and that security measures are in place to mitigate risks associated with this vulnerability.
Vulnerability Details
The Cross-Site Request Forgery (CSRF) vulnerability in the MercadoLibre Integration plugin allows for stored XSS. This issue affects all versions up to and including 1.1. The CVSS score for this vulnerability is 7.1, classifying it as high severity due to the potential for significant impact on confidentiality, integrity, and availability.
The vulnerability is classified under CWE-352, which pertains to Cross-Site Request Forgery. The plugin's reliance on user interaction for exploitation further complicates its threat landscape, making it imperative for users to be aware of the risks involved.
Technical Analysis
The root cause of this vulnerability lies in inadequate validation of user inputs, allowing attackers to manipulate requests to the MercadoLibre Integration plugin. The attack vector is network-based, and the attack complexity is classified as low. No privileges are required to exploit this vulnerability, making it particularly dangerous.
User interaction is necessary for successful exploitation, as the attacker must trick the victim into executing an action that triggers the CSRF attack. The impact on confidentiality, integrity, and availability is assessed to be low, but the potential for misuse warrants immediate remediation.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is substantial, particularly for organizations that rely heavily on the MercadoLibre Integration for e-commerce activities. Attackers may leverage this vulnerability to gain unauthorized access, leading to data breaches or further compromises within the organization.
With a CVSS score of 7.1, this vulnerability falls into the high severity category, necessitating immediate action from security teams. The blast radius potential is significant due to the widespread use of the plugin, thus organizations should address this vulnerability in their priority patch cycle.
