Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU66919
Risk: Medium
CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-3033
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe 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.
Install updates from vendor's website.
