VAR-202211-0122

Vulnerability from variot - Updated: 2023-12-18 13:46

The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. By using special elements such as ".." and "/" separators, attackers can escape outside of the restricted location to access files or directories that are elsewhere on the system. Hitachi Vantara's Vantara Pentaho Exists in a past traversal vulnerability.Information may be obtained

CVE-2021-45448 (GCVE-0-2021-45448)

Vulnerability from cvelistv5 – Published: 2022-11-02 15:12 – Updated: 2025-05-02 15:48

Title

Pentaho Business Analytics Server - Pentaho Analyzer plugin exposes a service endpoint for templates which allows a user supplied path to access resources that are out of bounds.

Summary

Pentaho Business Analytics Server versions before 9.2.0.2 and 8.3.0.25 using the Pentaho Analyzer plugin exposes a service endpoint for templates which allows a user-supplied path to access resources that are out of bounds. The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. By using special elements such as ".." and "/" separators, attackers can escape outside of the restricted location to access files or directories that are elsewhere on the system.

Severity

7.1 (High)
