A reflected cross-site scripting (XSS) vulnerability in the AdvancedSearch functionality of Silverpeas Core before version 6.4.6 allows attackers to execute arbitrary JavaScript in the context of a user's browser via crafted input.
AnalysisAI
Reflected cross-site scripting (XSS) in Silverpeas Core before version 6.4.6 allows unauthenticated remote attackers to execute arbitrary JavaScript in users' browsers via malicious input to the AdvancedSearch functionality. The vulnerability requires user interaction (clicking a crafted link) and affects confidentiality and integrity with partial technical impact. Publicly available exploit code exists, and CISA SSVC assessment confirms proof-of-concept availability, though this vulnerability is not yet confirmed in active widespread exploitation.
Technical ContextAI
The vulnerability resides in the AdvancedSearch feature of Silverpeas Core, a digital workplace collaboration platform. The root cause is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation), indicating that user-supplied input is not properly sanitized or escaped before being reflected back to the client in HTML responses. Silverpeas processes search parameters without adequate output encoding, allowing attackers to inject arbitrary HTML and JavaScript that executes with the privileges of the authenticated user viewing the search results. The attack vector is network-based, complexity is low, and no privileges are required to craft the malicious payload, though successful exploitation depends on a legitimate user interacting with the attacker-controlled link.
RemediationAI
Upgrade Silverpeas Core to version 6.4.6 or later, which includes the fix referenced in GitHub pull request #1421. This is the primary and vendor-confirmed remediation. For organizations unable to upgrade immediately, implement compensating controls: disable or restrict access to the AdvancedSearch functionality via network or application-level access controls (e.g., restrict search endpoints to authenticated internal users only, block external access to /search endpoints); deploy a Web Application Firewall (WAF) configured with XSS detection rules to filter malicious input patterns in search parameters; and enforce Content Security Policy (CSP) headers to prevent inline script execution and limit script sources to trusted origins. Note that WAF-based mitigations may impact legitimate search functionality if overly restrictive, and CSP deployment requires thorough testing to avoid breaking application features. These workarounds do not eliminate the underlying vulnerability and are temporary measures pending patch deployment.
