AI Insight

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

Firefox session-restore vulnerability allows same-origin policy bypass and cross-site scripting via SessionStore data restoration.

Vulnerability

Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19 contain an unspecified vulnerability in the session-restore feature. The bug involves restoration of SessionStore data, which can be exploited to bypass the same-origin policy and inject content into documents from other domains, leading to cross-site scripting (XSS) attacks [1].

Exploitation

The attack vector is not fully disclosed in available references, but it likely requires an attacker to craft malicious SessionStore data that is restored by the browser. No direct user interaction beyond normal browsing and session restore is needed, as the vulnerability is triggered automatically during restore.

Impact

Successful exploitation allows an attacker to bypass the same-origin policy and inject arbitrary content into documents associated with other domains, leading to cross-site scripting (XSS) attacks. This could result in information disclosure, session hijacking, or arbitrary actions in the context of the target site.

Mitigation

Firefox 3.0.5 and 2.0.0.19, released on December 16, 2008, patch this issue [1]. Users should upgrade to these or later versions. No workarounds are available. This CVE is not listed in CISA's Known Exploited Vulnerabilities catalog.
