GHSA-8m5h-hrqm-pxm2
No affected components available
Impact
The default implementation of Validator.getValidDirectoryPath(String, String, File, boolean) may incorrectly treat the tested input string as a child of the specified parent directory. This potentially could allow control-flow bypass checks to be defeated if an attack can specify the entire string representing the 'input' path.
Patches
This vulnerability is patched in release 2.3.0.0 of ESAPI. See https://github.com/ESAPI/esapi-java-legacy/releases/tag/esapi-2.3.0.0 for details.
Workarounds
Yes; in theory, one could write the own implementation of the Validator interface. This would most easily be done by sub-classing a version of the affected DefaultValidator class and then overriding the affected getValidDirectoryPath() to correct the issue. However, this is not recommended.
