3DescriptionCVE.org
A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection.
AnalysisAI
Tar archive extraction allows hidden file injection by local authenticated users through crafted malicious archives, bypassing pre-extraction inspection mechanisms and enabling introduction of attacker-controlled files. The vulnerability affects Red Hat Enterprise Linux versions 6 through 10, requires local access and user interaction (extraction action), and presents a moderate integrity risk (CVSS 5.0) with no confirmed active exploitation or public proof-of-concept at time of analysis.
Technical ContextAI
The vulnerability exists in the tar utility's handling of archive contents during extraction. It is classified as CWE-434 (Unrestricted Upload of File with Dangerous Type), indicating a failure to properly validate or restrict file types and paths during archive extraction. The flaw allows an attacker to craft a specially formatted tar archive containing hidden files (likely leveraging tar's support for special file naming, path traversal sequences, or metadata manipulation) that evade conventional pre-extraction scanning tools. When a local user extracts such an archive with their privileges, the malicious files are written to unintended locations on the filesystem, bypassing detection mechanisms that examine the archive before extraction begins.
RemediationAI
Apply the security update provided by Red Hat for your RHEL version through standard package management (yum or dnf). Check https://access.redhat.com/security/cve/CVE-2026-5704 for the specific patched tar package version corresponding to your RHEL release. Until patching is complete, implement procedural controls: restrict archive extraction to trusted sources only, require administrative review before extracting archives from external origins, and educate users to avoid extracting archives from untrusted parties. Consider using alternative archive extraction tools with stricter validation if available for your workflows, though the underlying issue may affect system tar more broadly.
