Normally, the `--command` argument of `flatpak run` expects to be given a command to run in the specified Flatpak app, optionally along with some arguments. However it is possible to instead pass `bwrap` arguments to `--command=`, such as `--bind`. It's possible to pass an arbitrary `commandline` to the portal interface `org.freedesktop.portal.Background.RequestBackground` from within a Flatpak app. When this is converted into a `--command` and arguments, it achieves the same effect of passing arguments directly to `bwrap`, and thus can be used for a sandbox escape. The solution is to pass the `--` argument to `bwrap`, which makes it stop processing options. This has been supported since bubblewrap 0.3.0. All supported versions of Flatpak require at least that version of bubblewrap. xdg-desktop-portal version 1.18.4 will mitigate this vulnerability by only allowing Flatpak apps to create .desktop files for commands that do not start with --. The vulnerability is patched in 1.15.8, 1.10.9, 1.12.9, and 1.14.6." } ], "source": { "advisory": "GHSA-phv6-cpc2-2fgj", "discovery": "UNKNOWN" } }, "adp": [ { "title": "CISA ADP Vulnrichment", "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-32462", "role": "CISA Coordinator", "options": [ { "Exploitation": "None" }, { "Automatable": "No" }, { "Technical Impact": "Total" } ], "version": "2.0.3", "timestamp": "2024-04-20T04:00:12.336436Z" } } } ], "affected": [ { "cpes": [ "cpe:2.3:a:flatpak:flatpak:*:*:*:*:*:*:*:*" ], "vendor": "flatpak", "product": "flatpak", "versions": [ { "status": "affected", "version": "1.15.0", "lessThan": "1.15.8", "versionType": "semver" } ], "defaultStatus": "unknown" } ], "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-04T17:51:25.150Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T02:13:39.161Z" }, "title": "CVE Program Container", "references": [ { "name": "https://github.com/flatpak/flatpak/security/advisories/GHSA-phv6-cpc2-2fgj", "tags": [ "x_refsource_CONFIRM", "x_transferred" ], "url": "https://github.com/flatpak/flatpak/security/advisories/GHSA-phv6-cpc2-2fgj" }, { "name": "https://github.com/flatpak/flatpak/commit/72016e3fce8fcbeab707daf4f1a02b931fcc004d", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/flatpak/flatpak/commit/72016e3fce8fcbeab707daf4f1a02b931fcc004d" }, { "name": "https://github.com/flatpak/flatpak/commit/81abe2a37d363f5099c3d0bdcd0caad6efc5bf97", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/flatpak/flatpak/commit/81abe2a37d363f5099c3d0bdcd0caad6efc5bf97" }, { "name": "https://github.com/flatpak/flatpak/commit/b7c1a558e58aaeb1d007d29529bbb270dc4ff11e", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/flatpak/flatpak/commit/b7c1a558e58aaeb1d007d29529bbb270dc4ff11e" }, { "name": "https://github.com/flatpak/flatpak/commit/bbab7ed1e672356d1a78b422462b210e8e875931", "tags": [ "x_refsource_MISC", "x_transferred" ], "url": "https://github.com/flatpak/flatpak/commit/bbab7ed1e672356d1a78b422462b210e8e875931" }, { "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ZFNSCFJVMAQK5AF55JBN7OSJP3CREDBD/", "tags": [ "x_transferred" ] }, { "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IB6VQAF5S2YOBULDHPUKPOEIKONOP5KO/", "tags": [ "x_transferred" ] }, { "url": "http://www.openwall.com/lists/oss-security/2024/04/18/5", "tags": [ "x_transferred" ] } ] } ] } }
