CVE-2009-2814

Vulnerability

The Wiki Server component in Apple Mac OS X 10.5.8 contains a cross-site scripting (XSS) vulnerability. The flaw occurs when the server processes search requests that contain data not encoded in UTF-8. Insufficient input validation allows arbitrary HTML or script injection into the response page.

Exploitation

An unauthenticated remote attacker can craft a search request with non-UTF-8 encoded payload containing malicious script. The request is sent to the Wiki Server endpoint. No prior authentication or special privileges are required; the attacker only needs network access to the server. When a victim views the search results page, the injected script executes in the context of their browser.

Impact

Successful exploitation allows the attacker to execute arbitrary web script or HTML in the victim's browser session. This can lead to session hijacking, defacement, or other client-side attacks that compromise the confidentiality and integrity of the user's interaction with the Wiki Server.

Mitigation

The provided reference does not contain specific mitigation details for this CVE. No workaround is documented in the available sources. Given the age of the vulnerability, applying the latest security updates from Apple is recommended.
