This vulnerability allows for improper neutralization of input during web page generation, resulting in Cross-site Scripting (XSS) vulnerabilities in the bPlugins Button Block plugin. Specifically, the vulnerability can lead to stored XSS attacks, which could be leveraged by attackers to execute malicious scripts in the context of users' browsers. The affected versions are from n/a through 1.1.9.
The CVSS score for this vulnerability is 6.5, categorizing it as medium severity. This indicates a moderate risk to organizations, as the vulnerability can be exploited by attackers with low attack complexity and minimal privileges required. User interaction is also necessary, making it essential for organizations to understand the implications.
Risk to organizations includes potential unauthorized access to sensitive information and the ability to manipulate web content. The exploitation of this vulnerability could have significant implications, especially in environments that utilize the bPlugins Button Block for user-generated content.
Organizations should prioritize patching immediately. The urgency is heightened due to the potential for stored XSS attacks, which can compromise user data and application integrity.
Vulnerability Details
The official CVE description outlines that the vulnerability exists in the bPlugins Button Block plugin, affecting versions from n/a through 1.1.9. The primary vulnerability type is classified under CWE-79, indicating improper neutralization of input. The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L.
The CVSS score of 6.5 indicates a medium severity, with a base severity rating provided by Patchstack. The attack vector is classified as network-based, and the attack complexity is low, allowing attackers to exploit this vulnerability relatively easily.
The affected product is the bPlugins Button Block, which is widely utilized in WordPress. The vulnerability was published on January 9, 2025, and has been marked as modified in the vulnerability database.
Technical Analysis
The root cause of this vulnerability stems from the improper handling of user input, which allows attackers to inject malicious scripts that can be stored and later executed in other users' browsers. The attack vector is via the network, and the complexity is low because it does not require advanced skills to exploit.
The vulnerability requires low privileges, making it accessible to a wide range of potential attackers. User interaction is required, as the attack relies on tricking users into executing the malicious payload.
Regarding impacts, the confidentiality and integrity of the affected systems may be compromised, as attackers can manipulate the data seen by users. However, the availability impact is rated as low, meaning that the service itself is unlikely to go down due to this vulnerability.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant, particularly for organizations that utilize the bPlugins Button Block for user-generated content. Attackers may leverage this vulnerability to execute malicious scripts, potentially leading to data theft, session hijacking, or other malicious activities.
The blast radius potential is concerning, as successful exploitation could impact all users interacting with the affected plugin. Organizations must consider the implications of stored XSS vulnerabilities, as they can be used to compromise user accounts and gain unauthorized access to sensitive information.
Given the moderate CVSS score of 6.5, organizations should address this vulnerability in their priority patch cycle. The urgency is further emphasized by its potential for exploitation in the wild, necessitating immediate attention.
