https://notcve.org/view.php?id=CVE-2021-32703
Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.011, and 21.0.3, there was a lack of ratelimiting on the shareinfo endpoint. This may have allowed an attacker to enumerate potentially valid share tokens. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-375p-cxxq-gc9p https://github.com/nextcloud/server/pull/26945 https://hackerone.com/reports/1173684 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BVZS26RDME2DYTKET5AECRIZDFUGR2AZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J63NBVPR2AQCAWRNDOZSGRY5II4WS2CZ https://security.gentoo.org/glsa/202208-17 • CWE-307: Improper Restriction of Excessive Authentication Attempts CWE-799: Improper Control of Interaction Frequency •
CVSS: 8.8EPSS: 0%CPEs: 5EXPL: 0CVE-2021-32688 – Application specific tokens can change their own scope
https://notcve.org/view.php?id=CVE-2021-32688
Nextcloud Server is a Nextcloud package that handles data storage. Nextcloud Server supports application specific tokens for authentication purposes. These tokens are supposed to be granted to a specific applications (e.g. DAV sync clients), and can also be configured by the user to not have any filesystem access. Due to a lacking permission check, the tokens were able to change their own permissions in versions prior to 19.0.13, 20.0.11, and 21.0.3. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-48m7-7r2r-838r https://github.com/nextcloud/server/pull/27000 https://hackerone.com/reports/1193321 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BVZS26RDME2DYTKET5AECRIZDFUGR2AZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J63NBVPR2AQCAWRNDOZSGRY5II4WS2CZ https://security.gentoo.org/glsa/202208-17 • CWE-285: Improper Authorization CWE-552: Files or Directories Accessible to External Parties •

CVSS: 8.8EPSS: 0%CPEs: 5EXPL: 0CVE-2021-32679 – Filenames not escaped by default in controllers using DownloadResponse
https://notcve.org/view.php?id=CVE-2021-32679
Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.0.11, and 21.0.3, filenames where not escaped by default in controllers using `DownloadResponse`. When a user-supplied filename was passed unsanitized into a `DownloadResponse`, this could be used to trick users into downloading malicious files with a benign file extension. This would show in UI behaviours where Nextcloud applications would display a benign file extension (e.g. JPEG), but the file will actually be downloaded with an executable file extension. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-3hjp-26x8-mhf6 https://github.com/nextcloud/server/pull/27354 https://hackerone.com/reports/1215263 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BVZS26RDME2DYTKET5AECRIZDFUGR2AZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J63NBVPR2AQCAWRNDOZSGRY5II4WS2CZ https://security.gentoo.org/glsa/202208-17 • CWE-116: Improper Encoding or Escaping of Output •
CVSS: 5.3EPSS: 0%CPEs: 5EXPL: 0CVE-2021-32678 – Ratelimit not applied on OCS API responses
https://notcve.org/view.php?id=CVE-2021-32678
Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.0.11, and 21.0.3, ratelimits are not applied to OCS API responses. This affects any OCS API controller (`OCSController`) using the `@BruteForceProtection` annotation. Risk depends on the installed applications on the Nextcloud Server, but could range from bypassing authentication ratelimits or spamming other Nextcloud users. The vulnerability is patched in versions 19.0.13, 20.0.11, and 21.0.3. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-48rx-3gmf-g74j https://github.com/nextcloud/server/pull/27329 https://hackerone.com/reports/1214158 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BVZS26RDME2DYTKET5AECRIZDFUGR2AZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J63NBVPR2AQCAWRNDOZSGRY5II4WS2CZ https://security.gentoo.org/glsa/202208-17 • CWE-307: Improper Restriction of Excessive Authentication Attempts CWE-799: Improper Control of Interaction Frequency •
