Summary

A flaw was found in OpenSCAP. When decomposing a Source DataStream (SDS) file, the application does not properly validate relative file path attributes, leading to a path traversal vulnerability. An attacker can exploit this flaw by tricking a user or automated system into decomposing a crafted datastream containing directory traversal sequences. Successful exploitation allows unauthorized file creation or modification outside the intended target directory with the permissions of the executing process.

Risk Assessment

An attacker could create or modify files outside the intended directory, potentially compromising system integrity, overwriting configuration files, or escalating privileges. This requires tricking a user or system into processing a malicious file.

Recommendation

Update OpenSCAP to a version containing the path validation fix. Avoid processing untrusted datastream files.
