This vulnerability allows for Stored Cross-site Scripting (XSS) within the osuthorpe Easy Shortcode Buttons plugin. The issue affects versions from n/a through 1.2, with potential impacts on users and organizations utilizing this plugin in their WordPress installations. As the CVSS score is 6.5, this vulnerability is classified as medium severity, indicating that it requires attention but may not be immediately critical.
Risk to organizations includes the potential for unauthorized access to sensitive information, manipulation of web content, and possible website defacement. Attackers may leverage this vulnerability to execute arbitrary scripts in the context of the user’s browser, leading to session hijacking or phishing attacks. Organizations should prioritize remediation to prevent exploitation.
Currently, there is no public exploit confirmed for this vulnerability, but the ease of exploitation due to the low attack complexity and required user interaction means it remains a concern. Organizations should prioritize patching immediately.
Given the nature of this vulnerability, it is crucial for organizations to assess their use of the Easy Shortcode Buttons plugin and take necessary actions to mitigate risks.
Vulnerability Details
The vulnerability is a result of improper neutralization of input during web page generation, specifically allowing for Stored XSS. This vulnerability affects the osuthorpe Easy Shortcode Buttons plugin versions from n/a to 1.2. The official description indicates a risk of unauthorized script execution.
CVSS score is rated at 6.5, indicating a medium severity level. The attack vector is classified as network-based, while the attack complexity is low, requiring only low privileges and user interaction.
Impact scores indicate low confidentiality, integrity, and availability impacts. The common weakness enumeration (CWE) associated is CWE-79, which pertains to improper neutralization of input.
Technical Analysis
The root cause of this vulnerability stems from improper input validation, allowing an attacker to inject malicious scripts that get executed in users' browsers. The attack vector for this vulnerability is primarily network-based, which means attackers can exploit it remotely.
The attack complexity is low, suggesting that attackers with minimal skill can exploit this vulnerability. It requires low privileges, meaning that even users with basic access can potentially trigger the exploit. User interaction is required, as the malicious script must be activated by the user's actions.
The potential impacts include low confidentiality, integrity, and availability. Organizations must monitor for signs of exploitation and implement measures to prevent such attacks.
Risk & Impact Analysis
Real-world deployment of the vulnerable Easy Shortcode Buttons plugin poses risks of unauthorized access and exploitation. Attackers may use this vulnerability to steal sensitive user data, hijack sessions, or spread malware.
The blast radius for this vulnerability is significant, as it could affect a wide range of users if the plugin is widely adopted. Organizations that do not prioritize patching may find themselves increasingly vulnerable to attacks leveraging this weakness.
Given the CVSS score of 6.5 and the fact that it is not included in the Known Exploited Vulnerabilities (KEV) database, organizations should still address this vulnerability in their patch cycle to mitigate potential risks.
