CVE-2024-1551

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 123 Firefox ESR versions prior to 115.8 Thunderbird versions prior to 115.8

Description The issue is related to the incorrect honoring of Set-Cookie response headers in multipart HTTP responses. If an attacker can control the Content-Type response header and part of the response body, they can inject Set-Cookie response headers that would be honored by the browser. This allows a remote attacker to inject arbitrary HTTP headers, such as Set-Cookie.

Recommendations For Firefox versions prior to 123, update to version 123 or later to resolve the issue. For Firefox ESR versions prior to 115.8, update to version 115.8 or later to resolve the issue. For Thunderbird versions prior to 115.8, update to version 115.8 or later to resolve the issue.
