Official description

Uncontrolled Search Path Element vulnerability in Pandora FMS on all allows Leveraging/Manipulating Configuration File Search Paths. This vulnerability allows access to files with sensitive information. This issue affects Pandora FMS: from 700 through 772.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Uncontrolled Search Path Element

The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.

How developers prevent this class of flaw

  • Hard-code the search path to a set of known-safe values (such as system directories), or only allow them to be specified by the administrator in a configuration file. Do not allow these settings to be modified by an external party. Be careful to avoid related weaknesses such as CWE-426 and CWE-428.
  • When invoking other programs, specify those programs using fully-qualified pathnames. While this is an effective approach, code that uses fully-qualified pathnames might not be portable to other systems that do not use the same pathnames. The portability can be improved by locating the full-qualified paths in a centralized, easily-modifiable location within the source code, and having the code refer to these paths.
  • Remove or restrict all environment settings before invoking other programs. This includes the PATH environment variable, LD_LIBRARY_PATH, and other settings that identify the location of code libraries, and any application-specific search paths.
