AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Cross-site scripting (XSS) vulnerability in MediaWiki 1.3.4 and earlier via the 'raw' page output mode allows remote attackers to inject arbitrary web script or HTML.

Vulnerability

The vulnerability is a cross-site scripting (XSS) flaw in the 'raw' page output mode of MediaWiki versions 1.3.4 and earlier. When a page is requested in raw mode, user-supplied input is not properly sanitized, allowing injection of arbitrary web script or HTML. [1]

Exploitation

An attacker can exploit this by crafting a malicious URL that triggers the raw output mode and includes injected script. No authentication is required; the attacker only needs to convince a victim to visit the crafted link. [1]

Impact

Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the victim's browser, potentially leading to session hijacking, defacement, or theft of sensitive information. [1]

Mitigation

The vulnerability is fixed in MediaWiki 1.3.5 and later. Users should upgrade to the latest version. No workaround is mentioned in the available references. [2]
