This vulnerability allows improper neutralization of input during web page generation, specifically resulting in a Cross-site Scripting (XSS) vulnerability in the Porto theme. The issue affects versions from n/a up to and including 7.6.2. As a result, attackers may leverage this vulnerability to execute malicious scripts in the context of users' browsers.
The CVSS score for this vulnerability is 7.1, classified as high severity. This score indicates that the vulnerability is exploitable over the network with low complexity and does not require elevated privileges. However, it does necessitate user interaction, which could increase the likelihood of exploitation.
Risk to organizations includes potential data theft, session hijacking, and unauthorized actions taken by the attacker on behalf of the user. Organizations should prioritize patching immediately.
As of now, there is no known exploit available in the wild, but the existence of the vulnerability itself poses a significant risk, especially if it gains attention from malicious actors.
Organizations should address this vulnerability in their priority patch cycle to mitigate risks associated with reflected XSS attacks.
Vulnerability Details
The improper neutralization of input during web page generation vulnerability allows reflected XSS in the Porto theme. The issue affects versions from n/a to <= 7.6.2.
The CVSS score of 7.1 indicates a high severity level, reflecting the potential impact of exploitation. The vulnerability is classified under CWE-79.
Technical Analysis
The root cause of this vulnerability lies in inadequate input validation that allows attackers to inject malicious scripts into web pages rendered for end users. The attack vector is network-based, and the complexity is low, meaning that the exploit can be executed easily by attackers with minimal skills.
No privileges are required for exploitation, but user interaction is necessary, as the victim must click on a crafted link or visit a malicious page. The impact on confidentiality, integrity, and availability is low, but the potential for data theft and unauthorized actions remains significant.
Risk & Impact Analysis
Real-world deployment of the Porto theme may expose organizations to considerable risks, especially in environments handling sensitive data. The potential for data theft, unauthorized access, and manipulation of user sessions presents a considerable threat.
Organizations using this theme should assess their current exposure and consider the blast radius of a successful attack, which could affect all users interacting with the compromised application.
Given the CVSS score and the urgency of this vulnerability, organizations should address this issue in their priority patch cycle to mitigate the associated risks.
