Lifecycle Timeline
1DescriptionNVD
An issue was discovered in Wind River VxWorks 6.9 and 7. The function `tarExtract` implements TAR file extraction and thereby also processes files within an archive that have relative or absolute file paths. A developer using the "tarExtract" function may expect that the function will strip leading slashes from absolute paths or stop processing when encountering relative paths that are outside of the extraction path, unless otherwise forced. This could lead to unexpected and undocumented behavior, which in general could result in a directory traversal, and associated unexpected behavior.
AnalysisAI
An issue was discovered in Wind River VxWorks 6.9 and 7. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
Technical ContextAI
This vulnerability is classified as Path Traversal (CWE-22), which allows attackers to access files and directories outside the intended path. An issue was discovered in Wind River VxWorks 6.9 and 7. The function `tarExtract` implements TAR file extraction and thereby also processes files within an archive that have relative or absolute file paths.

This could lead to unexpected and undocumented behavior, which in general could result in a directory traversal, and associated unexpected behavior. Affected products include: Windriver Vxworks.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate and canonicalize file paths. Use chroot or sandboxing. Reject input containing path separators or '../' sequences.
