CVE-2025-47273

Public on

Last Modified: UTC

Moderate Moderate Impact What does this mean?
7.1 CVSS v3 Base Score

Description

A path traversal vulnerability in the Python setuptools library allows attackers with limited system access to write files outside the intended temporary directory by manipulating package download URLs. This flaw bypasses basic filename sanitization and can lead to unauthorized overwrites of important system files, creating opportunities for further compromise. While it doesn't expose data or require user interaction, it poses a high integrity risk and is especially concerning in environments that rely on automated package handling or internal tooling built on setuptools.

Statement

Red Hat Product Security has rated this vulnerability "Moderate" based on the impact of the damage caused by a successful exploitation and the pre-requisites.

  • Exploitation requires that the attacker have limited code execution access to a Python environment where they can trigger the vulnerable PackageIndex.download() function—this might be via a script, plugin, or automated job. Full admin rights aren't needed but a user with no access at all will be unable to exploit this vulnerability.
  • The vulnerability impacts the integrity of the system within the same security boundary—it does not enable access or compromise across trust boundaries (e.g., from one container to another or from user space to kernel).
  • Successful exploitation only allows the attacker to "create" new files. The vulnerability does not provide access to existing files and by an extension to any confidential information.
  • Arbitrary file writes can overwrite critical config files, executables, or scripts. This can lead to persistent code execution, system misconfiguration, or unauthorized behavior, especially in automated environments. While overwriting critical files could theoretically lead to service disruption, the vulnerability in isolation does not inherently cause denial of service. The exploit doesn't target availability directly, and in many cases, systems may continue running.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authorities (CNA) source for its products and services (see Red Hat classifications ).

CVSS v3 Score Breakdown Red Hat NVD

Attack Vector Network Network
Attack Complexity Low Low
Privileges Required Low Low
User Interaction None None

Frequently Asked Questions

Why is Red Hat's CVSS v3 score or Impact different from other vendors?

 For open source software shipped by multiple vendors, the CVSS base scores may vary for each vendor's version depending on the version they ship, how they ship it, the platform, and even how the software is compiled. This makes scoring of vulnerabilities difficult for third-party vulnerability databases such as NVD that only provide a single CVSS base score for each vulnerability. Red Hat scores reflect how a vulnerability affects our products specifically.

For more information, see https://access.redhat.com/solutions/762393.

My product is listed as "Under investigation" or "Affected", when will Red Hat release a fix for this vulnerability?
  • "Under investigation" doesn't necessarily mean that the product is affected by this vulnerability. It only means that our Analysis Team is still working on determining whether the product is affected and how it is affected.
  • "Affected" means that our Analysis Team has determined that this product is affected by this vulnerability and might release a fix to address this in the near future.

What can I do if my product is listed as "Will not fix"?

 A "will not fix" status means that a fix for an affected product version is not planned or not possible due to complexity, which may create additional risk.

Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
  • Upgrade to a supported product version that includes a fix for this vulnerability (recommended).
  • Apply a mitigation (if one exists).
  • Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.

What can I do if my product is listed as "Fix deferred"?

 A deferred status means that a fix for an affected product version is not guaranteed due to higher-priority development work.

Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
  • Apply a mitigation (if one exists).
  • Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
  • Red Hat Engineering focuses on addressing high-priority issues based on their complexity or limited lifecycle support. Therefore, lower-priority issues will not receive immediate fixes.

What is a mitigation?

 A mitigation is an action that can be taken to reduce the impact of a security vulnerability, without deploying any fixes.

I have a Red Hat product but it is not in the above list, is it affected?

 The listed products were found to include one or more of the components that this vulnerability affects. These products underwent a thorough evaluation to determine their affectedness by this vulnerability. Note that layered products (such as container-based offerings) that consume affected components from any of the products listed in this table may be affected and are not represented.

Why is my security scanner reporting my product as vulnerable to this vulnerability even though my product version is fixed or not affected?

 In order to maintain code stability and compatibility, Red Hat usually does not rebase packages to entirely new versions. Instead, we backport fixes and new features to an older version of the package we distribute. This can result in some security scanners that only consider the package version to report the package as vulnerable. To avoid this, we suggest that you use an approved vulnerability scanner from our This content is not included.Red Hat Vulnerability Scanner Certification program.

My product is listed as "Out of Support Scope". What does this mean?

 When a product is listed as "Out of Support Scope", it means a vulnerability with the impact level assigned to this CVE is no longer covered by its current support lifecycle phase. The product has been identified to contain the impacted component, but analysis to determine whether it is affected or not by this vulnerability was not performed. The product should be assumed to be affected. Customers are advised to apply any mitigation options documented on this page, consider removing or disabling the impacted component, or upgrade to a supported version of the product that has an update available.
