This vulnerability allows for stored Cross-site Scripting (XSS) within the Posts Footer Manager plugin developed by Data443 Risk Mitigation, Inc. This issue affects versions up to 2.1.0. Exploiting this vulnerability can lead to unauthorized script execution in the context of the affected web application, posing significant risks to user data and application integrity.
The CVSS score for this vulnerability is 5.9, indicating a medium severity level. Organizations should be aware that even medium-severity vulnerabilities can be exploited under certain conditions, especially given the nature of XSS attacks, which can lead to further attacks like session hijacking or data theft.
Currently, this vulnerability is classified as deferred, meaning that while it has been identified, the urgency for immediate remediation may not be as high as other critical vulnerabilities. However, organizations should still assess the risk it poses to their specific environment.
Given the exploitability of this vulnerability, organizations using the affected versions of the Posts Footer Manager should prioritize patching immediately to protect against potential XSS attacks.
Vulnerability Details
The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation, leading to stored XSS. The affected product is the Posts Footer Manager from Data443 Risk Mitigation, Inc., with the vulnerable versions being from n/a through 2.1.0.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L, indicating that the attack vector is network-based, the attack complexity is low, and high privileges are required to exploit it.
Technical Analysis
The root cause of this vulnerability lies in the inadequate sanitization of user input, allowing attackers to inject malicious scripts that are then stored and executed when users access affected pages. The attack vector is network-based, requiring the attacker to have high privileges and user interaction to exploit the vulnerability.
The attack complexity is low, as it does not require extensive knowledge or resources to execute. However, user interaction is required for the attack to be successful, as the user must visit the page where the malicious script is stored.
The impact on confidentiality, integrity, and availability is classified as low, but the potential for significant user data exposure or corruption exists, which can lead to broader implications for organizational security.
Risk & Impact Analysis
Risk to organizations includes potential data breaches, unauthorized access to user accounts, and loss of user trust. Given the nature of XSS attacks, attackers may leverage this vulnerability to conduct phishing attempts or steal sensitive information.
The urgency for remediation should be evaluated based on the specific deployment context. Organizations should address this vulnerability in their priority patch cycle to mitigate the associated risks.
