Description

This security bulletin contains information about 1 vulnerability.


1) Information disclosure (CVE-ID: CVE-2022-45414)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the way quoted certain HTML tags are handled within the email client. If a Thunderbird user quoted from an HTML email, for example by replying to the email, and the email contained either a VIDEO tag with the POSTER attribute or an OBJECT tag with a DATA attribute, a network request to the referenced remote URL was performed, regardless of a configuration to block remote content. An image loaded from the POSTER attribute was shown in the composer window. A remote attacker trick the victim into replying to a specially crafted email and force Thunderbird to initiate requests, potentially revealing sensitive information, such as IP address of the victim.
