Official description
Directory Traversal vulnerability in lsgwr spring boot online exam v.0.9 allows an attacker to execute arbitrary code via the FileTransUtil.java component.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Path Traversal: '/dir/../filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize /dir/../filename sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
