Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

MERCUSYS Mercury X18G 1.0.5 devices allow Directory Traversal via ../ in conjunction with a loginLess or login.htm URI (for authentication bypass) to the web server, as demonstrated by the /loginLess/../../etc/passwd URI.Show less

spring-boot-actuator-logview in a library that adds a simple logfile viewer as spring boot actuator endpoint. It is maven package "eu.hinsch:spring-boot-actuator-logview". In spring-boot-actuator-logview before version 0.2.13 there is a directory traversal vulnerability. The nature of this library is to expose a log file directory via admin (spring boot actuator) HTTP endpoints. Both the filename to view and a base folder (relative to the logging folder root) can be specified via request parameters. While the filename parameter was checked to prevent directory traversal exploits (so that `filename=../somefile` would not work), the base folder parameter was not sufficiently checked, so that `filename=somefile&base=../` could access a file outside the logging base directory). The vulnerability has been patched in release 0.2.13. Any users of 0.2.12 should be able to update without any issues as there are no other changes in that release. There is no workaround to fix the vulnerability other than updating or removing the dependency. However, removing read access of the user the application is run with to any directory not required for running the application can limit the impact. Additionally, access to the logview endpoint can be limited by deploying the application behind a reverse proxy.Show less

Apache Flink 1.5.1 introduced a REST handler that allows you to write an uploaded file to an arbitrary location on the local file system, through a maliciously modified HTTP HEADER. The files can be written to any location accessible by Flink 1.5.1. All users should upgrade to Flink 1.11.3 or 1.12.0 if their Flink instance(s) are exposed. The issue was fixed in commit a5264a6f41524afe8ceadf1d8ddc8c80f323ebc4 from apache/flink:master.Show less

A vulnerability has been reported to affect earlier QNAP devices running QTS 4.3.4 to 4.3.6. Caused by improper limitations of a pathname to a restricted directory, this vulnerability allows for renaming arbitrary files on the target system, if exploited. QNAP have already fixed this vulnerability in the following versions: QTS 4.3.6.0895 build 20190328 (and later) QTS 4.3.4.0899 build 20190322 (and later) This issue does not affect QTS 4.4.x or QTS 4.5.x.Show less

An authenticated path traversal vulnerability exists during package installation in Umbraco CMS <= 8.9.1 or current, which could result in arbitrary files being written outside of the site home and expected paths when installing an Umbraco package.Show less

DEXT5Upload 2.7.1262310 and earlier is affected by Directory Traversal in handler/dext5handler.jsp. This could allow remote files to be downloaded via a dext5CMD=downloadRequest action with traversal in the fileVirtualPath parameter (the attacker must provide the correct fileOrgName value).Show less

Flamingo (aka FlamingoIM) through 2020-09-29 allows ../ directory traversal because the only ostensibly unpredictable part of a file-transfer request is an MD5 computation; however, this computation occurs on the client side, and the computation details can be easily determined because the product's source code is available.Show less

Multiple directory traversal vulnerabilities in TerraMaster TOS <= 4.2.06 allow remote authenticated attackers to read, edit or delete any file within the filesystem via the (1) filename parameter to /tos/index.php?editor/fileGet, Event parameter to /include/ajax/logtable.php, or opt parameter to /include/core/index.php.Show less

A RCE vulnerability exists in Raysync below 3.3.3.8. An unauthenticated unauthorized attacker sending a specifically crafted request to override the specific file in server with malicious content can login as "admin", then to modify specific shell file to achieve remote code execution(RCE) on the hosting server.Show less
