This vulnerability allows for improper neutralization of input during web page generation, specifically in the Softaculous PageLayer plugin. The vulnerability is classified as Cross-site Scripting (XSS), enabling attackers to execute scripts in the context of the user’s browser, which can lead to data theft and session hijacking. With a CVSS score of 6.5, this vulnerability is deemed medium severity, indicating a notable risk to organizations leveraging the affected software.
Risk to organizations includes potential unauthorized access to sensitive information and manipulation of web content. Currently, there are no known public exploits for this vulnerability, but organizations should remain vigilant, as the risk of exploitation could increase. Given its impact, organizations should prioritize patching immediately.
As of the last update, the vulnerability status is deferred, which means it might not have been actively exploited in the wild. However, organizations should not take this as a sign to neglect remediation efforts.
Organizations using PageLayer version 1.9.4 or earlier are especially at risk. Immediate action is required to ensure that systems are secured against this vulnerability.
Vulnerability Details
The vulnerability is characterized by improper neutralization of input during web page generation, allowing for DOM-based XSS. The affected version is PageLayer: from n/a through <= 1.9.4. The CVSS score of 6.5 indicates that the attack vector is network-based, requiring low complexity and low privileges, with user interaction necessary for exploitation.
The vulnerability falls under the CWE-79 classification, which relates to improper input sanitization and reflects a common weakness in web applications.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly sanitize user inputs during the rendering of web pages. This oversight allows attackers to inject malicious scripts into web pages viewed by other users, potentially resulting in data theft, manipulation of web interfaces, or redirection to malicious sites.
The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it remotely without needing physical access to the affected system. The attack complexity is low, and it requires low privileges, indicating that even a non-privileged user could initiate an attack. User interaction is needed, as the attack relies on tricking the user into clicking on a malicious link or loading a compromised page.
The confidentiality, integrity, and availability impacts are all rated as low, indicating that while the potential for data exposure exists, the overall risk to the system’s operational capacity is minimal.
Risk & Impact Analysis
Real-world deployment risk for this vulnerability is significant, especially for organizations that rely heavily on web applications for user interaction. The potential for data breaches through XSS can lead to reputational damage, customer trust erosion, and financial losses.
This vulnerability poses a blast radius risk, particularly if exploited within large user bases, as the compromised scripts could affect multiple users simultaneously. Organizations should assess their current exposures and prioritize remediation efforts, especially considering the medium CVSS score.
Given the lack of public exploits and low EPSS score, organizations should still address this vulnerability in their patch cycles to avoid future risks. The urgency for remediation is marked as medium, indicating it should be scheduled within regular maintenance cycles.
