CVE-2022-45411 Explained : Impact and Mitigation

A critical vulnerability, CVE-2022-45411, has been identified in Mozilla Firefox ESR, Thunderbird, and Firefox software. This CVE allows for Cross-Site Tracing, potentially leading to unauthorized access to sensitive information.

Understanding CVE-2022-45411

This section delves into the nature of CVE-2022-45411 and its implications.

What is CVE-2022-45411?

CVE-2022-45411 refers to a Cross-Site Tracing vulnerability that arises when a server echoes a request back through the Trace method. This grants malicious actors the ability to execute Cross-Site Scripting (XSS) attacks and access authorization headers and cookies that are typically inaccessible to JavaScript. Despite browser security measures, servers using non-standard headers like X-Http-Method-Override can circumvent these protections, making the exploitation possible. Affected products include Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.

The Impact of CVE-2022-45411

The vulnerability poses a significant risk by allowing attackers to gain unauthorized access to sensitive information, compromising user data and system security.
