CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2021-21323 – Regression in DNS leakage from Tor windows
https://notcve.org/view.php?id=CVE-2021-21323
Brave is an open source web browser with a focus on privacy and security. In Brave versions 1.17.73-1.20.103, the CNAME adblocking feature added in Brave 1.17.73 accidentally initiated DNS requests that bypassed the Brave Tor proxy. Users with adblocking enabled would leak DNS requests from Tor windows to their DNS provider. (DNS requests that were not initiated by CNAME adblocking would go through Tor as expected.) This is fixed in Brave version 1.20.108 Brave es un navegador web de código abierto que se centra en la privacidad y la seguridad. • https://github.com/brave/brave-browser/issues/13527 https://github.com/brave/brave-browser/security/advisories/GHSA-mqjf-9x5g-2rv6 https://github.com/brave/brave-core/commit/12fe321eaad8acc1cbd1d70b4128f687777bcf15 https://github.com/brave/brave-core/pull/7769 https://hackerone.com/reports/1077022 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The implementation of Brave Desktop's privacy-preserving analytics system (P3A) between 1.1 and 1.18.35 logged the timestamp of when the user last opened an incognito window, including Tor windows. The intended behavior was to log the timestamp for incognito windows excluding Tor windows. Note that if a user has P3A enabled, the timestamp is not sent to Brave's server, but rather a value from:Used in last 24hUsed in last week but not 24hUsed in last 28 days but not weekEver used but not in last 28 daysNever usedThe privacy risk is low because a local attacker with disk access cannot tell if the timestamp corresponds to a Tor window or a non-Tor incognito window. La implementación del sistema de análisis de preservación de la privacidad de Brave Desktop (P3A) versiones entre 1.1 y 1.18.35, registró la marca de tiempo de la última vez que el usuario abrió una ventana de incógnito, incluyendo las ventanas Tor. El comportamiento previsto era registrar la marca de tiempo para las ventanas de incógnito, excluidas las ventanas Tor. • https://hackerone.com/reports/1024668 • CWE-312: Cleartext Storage of Sensitive Information •
