Given a reliable exploit primitive, this new process could be exploited again leading to arbitrary file read. References o Bug 1538028 # CVE-2023-23598: Arbitrary file read from GTK drag and drop on Linux Reporter: Tom Schuster Impact: high Description 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. References o Bug 1800425 # CVE-2023-23599: Malicious command could be hidden in devtools output on Windows Reporter: Vadim Impact: moderate Description 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. References o Bug 1777800 # CVE-2023-23600: Notification permissions persisted between Normal and Private Browsing on Android Reporter: Kazuki Nomoto of Waseda University Impact: moderate Description Per origin notification permissions were being stored in a way that didn't take into account what browsing context the permission was granted in. This lead to the possibility of notifications to be displayed during different browsing sessions. This bug only affects Firefox for Android. Other operating systems are unaffected. References o Bug 1787034 # CVE-2023-23601: URL being dragged from cross-origin iframe into same tab triggers navigation Reporter: Luan Herrera Impact: moderate Description Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which could lead to website spoofing attacks References o Bug 1794268 # CVE-2023-23602: Content Security Policy wasn't being correctly applied to WebSockets in WebWorkers Reporter: Dave Vandyke Impact: moderate Description 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. References o Bug 1800890 # CVE-2023-23603: Calls to <code>console.log</code> allowed bypasing Content Security Policy via format directive Reporter: Dan Veditz Impact: low Description 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. References o Bug 1800832 # CVE-2023-23604: Creation of duplicate <code>SystemPrincipal</code> from less secure contexts Reporter: Nika Layzell Impact: low Description 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. References o Bug 1802346 # CVE-2023-23605: Memory safety bugs fixed in Firefox 109 and Firefox ESR 102.7 Reporter: Mozilla developers Impact: high Description 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 run arbitrary code. References o Memory safety bugs fixed in Firefox 109 and Firefox ESR 102.7 # CVE-2023-23606: Memory safety bugs fixed in Firefox 109 Reporter: Mozilla developers Impact: high Description Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
