Published: September 1, 2022 / Updated: October 20, 2022


Vulnerability identifier: #VU66919
CSH Severity: Medium
CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N]
CVE-ID: CVE-2022-3033
CWE-ID: CWE-200
Exploitation vector: Remote access
Exploit availability: No public exploit available

Vulnerability details

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

The vulnerability exists due to the way Thunderbird handles the meta tag having the http-equiv="refresh" attribute in email messages when the user replies to an email. A remote attacker can send a specially crafted email to the victim and force the application to initiate requests to an external URL regardless of the configuration to block remote content.

Combined with other HTML elements and attributes in the email, it is possible to execute arbitrary JavaScript code included into the malicious message in the context of the message compose document and read or modify the contents of the message compose document, including the quoted original message, which could potentially contain the decrypted plaintext of encrypted data in the crafted email.
