A stored XSS vulnerability was discovered in BlogHub, a plugin in the CMS October. This article explores the vulnerability, its impact, and current status in detail. <\/p>\n\n\n\n
BlogHub<\/a> is a feature-rich plugin for the content management system October. The plugin features promotable tags, comment fields, custom meta fields, basic statistics, a views counter, and more. <\/p>\n\n\n\n This plugin is specifically designed to extend the features of October\u2019s blog plugin that is, RainLab.Blog<\/a>. The latest available version for this plugin is BlogHub v 1.3.9 released on January 21st, 2024. <\/p>\n\n\n\n A stored XSS or cross-site scripting<\/a> is a type of injection attack where a malicious code is directly injected into a vulnerable web application. It is also known as persistent XSS or second-order XSS. The vulnerability allows the attacker to execute malicious payloads into legitimate web applications. <\/p>\n\n\n\n XSS vulnerabilities are one of the most common vulnerabilities detected in websites and web applications. It usually occurs when a website uses user input within the output it generates without validating or encoding it.<\/p>\n\n\n\n Attackers send malicious scripts via XSS to a vulnerable web application section. The web app, having no way of knowing that the script shouldn\u2019t be trusted, executes it every time a user views it. Thus, resulting in the attacker gaining access to sensitive information within the user\u2019s browser. <\/p>\n\n\n\n The stored XSS vulnerability was found in the comments section of the BlogHub plugin. When a malicious XSS payload is added to the comments section, it persists and affects any user that visits the section in the CMS October\u2019s blogs. <\/p>\n\n\n\n The exploitation of the stored XSS vulnerability in the BlogHub plugin can result in the transmission of private data such as session cookies, tokens, and information to malicious actors leading to session hijacks. <\/p>\n\n\n\n Malicious payloads can be injected by attackers into the BlogHub comment section which when accessed by users could lead to unauthorized access to user accounts. <\/p>\n\n\n\n Malicious hackers can create phishing pages and link them to the vulnerable comment section. This would trick users into divulging sensitive information or downloading malicious files. <\/p>\n\n\n\n Once harmful scripts are inserted into the vulnerable website, attackers can tamper with the website\u2019s content by deleting, or editing it to manipulate users. <\/p>\n\n\n\n The stored XSS vulnerability was detected during a routine scan of the BlogHub plugin. The same was reported to the developers with recommendations to mitigate and patch the vulnerability and avoid its exploitation.<\/p>\n\n\n\n Based on the report provided relevant security patches were released by its developers. This was done through strict input sanitization.<\/p>\n\n\n\n To mitigate the stored XSS vulnerability and its possible impact, it is necessary to update your BlogHub plugin to the latest version released on January 21st, 2024, BlogHub plugin v1.3.9<\/a>. This version has the relevant security patches to secure your website from this vulnerability. <\/p>\n","protected":false},"excerpt":{"rendered":" A stored XSS vulnerability was discovered in BlogHub, a plugin in the CMS October.
