Summary
Niklas Baumstark discovered that a compromised web child process of Firefox
could disable web security opening restrictions, leading to a new child
process being spawned within the file:// context. An attacker could
potentially exploits this to obtain sensitive information. (CVE-2023-23597)
Tom Schuster discovered that Firefox was not performing a validation check
on GTK drag data. An attacker could potentially exploits this to obtain
sensitive information. (CVE-2023-23598)
Vadim discovered that Firefox was not properly sanitizing a curl command
output when copying a network request from the developer tools panel. An
attacker could potentially exploits this to hide and execute arbitrary
commands. (CVE-2023-23599)
Luan Herrera discovered that Firefox was not stopping navigation when
dragging a URL from a cross-origin iframe into the same tab. An attacker
potentially exploits this to spoof the user. (CVE-2023-23601)
Dave Vandyke discovered that Firefox did not properly implement CSP policy
when creating a WebSocket in a WebWorker. An attacker who was able to
inject markup into a page otherwise protected by a Content Security Policy
may have been able to inject an executable script. (CVE-2023-23602)
Dan Veditz discovered that Firefox did not properly implement CSP policy
on regular expression when using console.log. An attacker potentially
exploits this to exfiltrate data from the browser. (CVE-2023-23603)
Nika Layzell discovered that Firefox was not performing a validation check
when parsing a non-system html document via DOMParser::ParseFromSafeString.
An attacker potentially exploits this to bypass web security checks.
(CVE-2023-23604)
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2023-23605,
CVE-2023-23606)

Memory safety bugs fixed in Firefox 109 and Firefox ESR 102.7
Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and Firefox ESR 102.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to…

Content Security Policy wasn't being correctly applied to WebSockets in WebWorkers
A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy connect-src header to be ignored. This could lead to connections to restricted origins from inside WebWorkers. This vulnerability affects Firefox < 109, Fi…
-
Medium 6.5
Calls to console.log allowed bypassing Content Security Policy via format directive
Regular expressions used to filter out forbidden properties and values from style directives in calls to `console.log` weren't accounting for external URLs. Data could then be potentially exfiltrated from the browser. This vulnerability affects Firefox < 109,…
-
Medium 6.5
Creation of duplicate SystemPrincipal from less secure contexts
A duplicate `SystemPrincipal` object could be created when parsing a non-system html document via `DOMParser::ParseFromSafeString`. This could have lead to bypassing web security checks. This vulnerability affects Firefox < 109.

Unscored —
Logic bug in process allocation allowed to read arbitrary files
A compromised web child process could disable web security opening restrictions, leading to a new child process being spawned within the `file://` context. Given a reliable exploit primitive, this new process could be exploited again leading to arbitrary file…
-
Unscored —
Arbitrary file read from GTK drag and drop on Linux
Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to `DataTransfer.setData`. This vulnerability affects Firefox …
-
Unscored —
Malicious command could be hidden in devtools output on Windows
When copying a network request from the developer tools panel as a curl command the output was not being properly sanitized and could allow arbitrary commands to be hidden within. This vulnerability affects Firefox < 109, Firefox ESR < 102.7, and Thunderbird …
-
Unscored —
URL being dragged from cross-origin iframe into same tab triggers navigation
Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which could lead to website spoofing attacks This vulnerability affects Firefox < 109, Firefox ESR < 102.7, and Thunderbird < 102.7.
