CVE-2017-7823
CVSS v2.0
8.3
High
| Vector | AV:N/AC:M/Au:N/C:P/I:P/A:C |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 56
Firefox ESR versions prior to 52.4
Thunderbird versions prior to 52.4
Description
The content security policy (CSP) "sandbox" directive did not create a unique origin for the document, causing it to behave as if the "allow-same-origin" keyword were always specified. This could allow a Cross-Site Scripting (XSS) attack to be launched from unsafe content. The vulnerability is related to the implementation of the Content Security Policy (CSP) mechanism in Mozilla browsers, which failed to protect the structure of web pages using the sandbox directive, potentially allowing a remote attacker to perform cross-site scripting attacks.
Recommendations
For Firefox versions prior to 56, update to version 56 or later.
For Firefox ESR versions prior to 52.4, update to version 52.4 or later.
For Thunderbird versions prior to 52.4, update to version 52.4 or later.
