Summary

SciTokens C++ before version 1.4.1 is vulnerable to authorization bypass in path-based scope validation. The enforcer uses simple prefix comparison without path-segment boundaries, allowing a token scoped to one path to authorize access to sibling paths with the same prefix.

Risk Assessment

An attacker can gain unauthorized access to resources they should not have access to, violating access control.

Recommendation

Update scitokens-cpp to version 1.4.1 or later.

Original NVD description (English source)

SciTokens C++ is a minimal library for creating and using SciTokens from C or C++. Prior to version 1.4.1, scitokens-cpp is vulnerable to an authorization bypass in path-based scope validation. The enforcer used a simple string-prefix comparison when checking whether a requested resource path was covered by a token's authorized scope path. Because the check did not require a path-segment boundary, a token scoped to one path could incorrectly authorize access to sibling paths that merely started with the same prefix. This issue has been patched in version 1.4.1.
