Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Flaw remediation directly addresses the path traversal vulnerability in archive extraction by requiring updates to a supported version like 6.5.1.

SA-22 Unsupported System Components good match

prevent

Prohibits use of unsupported system components like Fedora Repository 3.8.1, which is unmaintained and vulnerable to Zip Slip exploitation.

SI-10 Information Input Validation good match

prevent

Information input validation enforces checks on archive paths during extraction to block path traversal attempts outside intended directories.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1100 Web Shell Persistence

A Web shell is a Web script that is placed on an openly accessible Web server to allow an adversary to use the Web server as a gateway into a network.

Why these techniques?

Path traversal in public-facing Fedora Repository archive extraction enables authenticated upload of crafted zip to write executable JSP web shell for RCE via unauthenticated GET.

Deeper analysisAI

CVE-2025-23011 is a path traversal vulnerability, referred to as "Zip Slip," affecting Fedora Repository version 3.8.1. The flaw exists in the component responsible for extracting uploaded archives, enabling files to be written to arbitrary locations outside the intended extraction directory.

A remote, authenticated attacker can exploit this vulnerability by uploading a specially crafted archive. Upon extraction, the archive can place an arbitrary JSP file in a location executable via an unauthenticated GET request, potentially allowing remote code execution. The vulnerability has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-23.

Fedora Repository 3.8.1, released on 2015-06-11, is no longer maintained, and mitigation requires migrating to a currently supported version such as 6.5.1 as of 2025-01-23.
