CVSS: 5.8EPSS: 0%CPEs: 136EXPL: 1CVE-2021-29425 – Possible limited path traversal vulnerabily in Apache Commons IO
https://notcve.org/view.php?id=CVE-2021-29425
In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value. En Apache Commons IO versiones anteriores a 2.7, Cuando se invoca el método FileNameUtils.normalize con una cadena de entrada inapropiada, como "//../foo" o "\\..\ foo", el resultado sería el mismo valor, por lo que posiblemente proporcionar acceso a archivos en el directorio principal, pero no más arriba (por lo tanto, salto de ruta "limited"), si el código de llamada usara el resultado para construir un valor de ruta • https://issues.apache.org/jira/browse/IO-556 https://lists.apache.org/thread.html/r01b4a1fcdf3311c936ce33d75a9398b6c255f00c1a2f312ac21effe1%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r0bfa8f7921abdfae788b1f076a12f73a92c93cc0a6e1083bce0027c5%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r0d73e2071d1f1afe1a15da14c5b6feb2cf17e3871168d5a3c8451436%40%3Ccommits.pulsar.apache.org%3E https://lists.apache.org/thread.html/r1c2f4683c35696cf6f863e3c107e37ec41305b1930dd40c17260de71%40%3Ccommits.pulsar.apache.org%3E https:/ • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

An issue was discovered in MediaWiki before 1.31.12 and 1.32.x through 1.35.x before 1.35.2. Users can bypass intended restrictions on deleting pages in certain "fast double move" situations. MovePage::isValidMoveTarget() uses FOR UPDATE, but it's only called if Title::getArticleID() returns non-zero with no special flags. Next, MovePage::moveToInternal() will delete the page if getArticleID(READ_LATEST) is non-zero. Therefore, if the page is missing in the replica DB, isValidMove() will return true, and then moveToInternal() will unconditionally delete the page if it can be found in the master. • https://lists.debian.org/debian-lts-announce/2021/05/msg00003.html https://lists.debian.org/debian-lts-announce/2021/05/msg00006.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/26UJGHF7LJDOCQN6A3Z4PM7PYRKENJHE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2OMSV7B2TCFBOCICN3B4SMQP5HVRJQIT https://phabricator.wikimedia.org/T272386 https://security.gentoo.org/glsa/202107-40 https://www.debian.org/security/2021/dsa-4889 •
