DescriptionCVE.org

Bludit CMS prior to commit 6732dde contains a reflected cross-site scripting vulnerability in the search plugin that allows unauthenticated attackers to inject arbitrary JavaScript by crafting a malicious search query. Attackers can execute malicious scripts in the browsers of users who visit crafted URLs containing the payload, potentially stealing session cookies or performing actions on behalf of affected users.

AnalysisAI

Reflected cross-site scripting in Bludit CMS search plugin allows unauthenticated attackers to inject arbitrary JavaScript through malicious search queries. When users visit attacker-crafted URLs containing the XSS payload, malicious scripts execute in their browsers, enabling session cookie theft and actions performed on behalf of victims. Publicly available exploit code exists; patch available via commit 6732dde.

Technical ContextAI

Bludit CMS is a flat-file content management system. The vulnerability resides in the search plugin's input validation mechanism, which fails to properly sanitize or encode user-supplied search query parameters before reflecting them in HTTP responses. This is a classic reflected XSS (CWE-79) where attacker-controlled input flows directly into the HTML output without context-appropriate encoding. The vulnerability affects all versions prior to commit 6732dde, as indicated by the CPE wildcard (cpe:2.3:a:bludit:bludit:*). The fix involves proper output encoding or input validation in the search functionality.

RemediationAI

Upgrade Bludit CMS to a version incorporating commit 6732dde or later; exact released version number not specified in advisory, so administrators should pull the latest development branch or wait for the next stable release that includes this commit. As immediate workaround, disable the search plugin entirely if not critical to operations, or implement Web Application Firewall (WAF) rules to block search requests containing common XSS payload patterns (script tags, event handlers, JavaScript: URLs). Additionally, enforce Content Security Policy (CSP) headers with strict script-src directives to mitigate impact if XSS executes despite input filtering. Apply httponly and secure flags to session cookies to prevent JavaScript-based theft. Note that disabling the search plugin removes functionality, and WAF bypass is possible with obfuscated payloads, so patching remains the primary fix.
